Danger due to electric current

• It is forbidden to carry out work on live device parts. The degree of protection for the open device is
• IP00! Potentially fatal voltages can be touched directly.
• When the motor runs independently due to air flowing through or if it continues to run down after being turned off, dangerous voltages of over 50 V can arise on the motor internal connections through operation of the generator.
• The safe isolation from the supply must be checked using a two-pole voltage detector.
• Even after disconnecting the mains voltage, life-threatening charges can appear between the protective ground “PE” and the mains connection.
• The protective earth is conducting high discharge currents (dependent on the switching frequency, current-source voltage and motor capacity). Earthing in compliance with EN specifications shall therefore be observed even for testing and trial conditions (EN 50 178, Art. 5.2.11). Without earthing, dangerous voltages can be present on the motor housing.
• Maintenance work may only be carried out by suitably qualified personnel.

Waiting period at least 3 minutes!

• Through use of capacitors, danger of death exists even after switching off the device through directly touching the energized parts or due to parts that have become energized due to faults.
• The controller housing may only be removed or opened when the power line has been switched off and a period of 5 minutes has elapsed since switching it off.

Attention, automatic restart!

• The fan/motor may switch on and off automatically for functional reasons.
• After power failure or mains disconnection an automatic restart of the fan takes place after voltage return!
• Wait for the fan to come to a complete standstill before approaching it!

Danger of being sucked in!
Do not wear loose or hanging clothing, jewellery, etc., tie together long hair and cover it.
Warning
High temperatures can occur on the motor surfaces and on the controller housing!
Even after switching off, dangerous temperatures can still occur in and on the device.

Product overview

3.1 Area of application/Notes on use
The fans / motors are not ready-for-use products, but conceived as components for ventilation systems (type designation see rating plate).
The fans may not be operated until they are installed in line with their intended use. The supplied and certified guard grille of ZIEHL-ABEGG SE fans is designed in accordance with DIN EN ISO 13857 Table 4 (from the age of 14 up). In the event of deviations, further structural protective measures must be taken for safe operation.

• Any use below -10 °C is dependent on not being subjected to unusual, sudden or mechanical loads or stresses on the material (see minimal permissible ambient temperature).
• Corrosion is possible at the cutting edges on sendzimir galvanised parts.

Warning
If the motor/fan is used in applications where a ignitable atmosphere can form in the event of a fault, e.g. due to leakage, the user must assess the risks of ignition and take appropriate precautions to prevent ignition.

3.2 Functional description
PMblue stands for fans with PM motors in connection with highest efficiency. Highly efficient electroni-cally switched motors with permanent solenoids and mounted PMIcontrol frequency inverters are used. Electronic commutation and speed control of the permanent magnet excited synchronous motor take place without a position sensor.
By transferring the motor and fan parameters to the frequency inverter, optimum operation at every operating point is possible thus giving you a drive system of maximum efficiency.
The devices are constructed in accordance with the general requirement in EN 61800-2 for adjustable speed electrical power systems and is intended for one- quadrant drives.
This assembly manual describes combinations of fans and frequency inverters in different models and frame sizes.
3.3 Frequency inverter with UL certification
Information
The attached frequency inverter PMIcontrol has a UL certification and bears the corresponding quality mark (see name plate on frequency inverter). This UL certification relates only to the frequency inverter, not to the complete fan.

3.4 Temperature management
The service life of devices with power electronics is decisively dependent on the ambient temper-atures. The longer electronic components are exposed to high ambient temperatures, the faster the deterioration and the more probable the failures.
The power electronics protects itself against excessive temperatures by active temperature manage-ment (power reduction).
3.5 Note on the ErP directive
ZIEHL-ABEGG SE wishes to point out that, based on the directive (EU) no. 327/2011 of the Commis-sion of 30th of March 2011 for enforcing directive 2009/125/EC (hereinafter referred to as ErP directive), the operational area of certain fans within the EU is bound by certain prerequisites.
The fan may only be used within the EU when it meets the requirements of the ErP directive.
If the said fan does not have a CE mark (cf. especially the rating plate), use of this product within the EU is not admissible.
All ErP-relevant information comprises measurements which are determined using a standardised measurement set-up. More details can be obtained from the manufacturer.
Further information about the ErP directive (Energy related Products- Directive) can be found on www.ziehl-abegg.de search key: “ErP”.

Mounting

4.1 General notes
Warning

• Mounting is only to be undertaken by trained service personnel. The system manufacturer or the machine builder and/or the user is responsible that the inherent installation and security information are harmonized with the valid standard and guidelines (EN ISO12100 / 13857).

• Check the fan for damage, e.g. cracks, dents or damage to the electric cables, before assembly.
  Start-up is not allowed in the case of transport damage!

• Wear safety clothing / shoes and cut-resistant safety gloves when handling!

• At a weight greater than 25 kg for men / 10 kg for women, the fan should be lifted out by two persons (according to REFA). The values may differ from country to country.

• Lift the fan out of the packaging with a lifting gear (lifting beam). Attachment points are solely the holes on the housing flange, motor bed, support plate, motor suspensions, fastening brackets and any crane eyes of the fan (depending on the shape of the fan).

• The chain/rope may not touch the impeller and the possibly mounted frequency inverter when lifting with the lifting beam, otherwise damage is possible.

• The custom designs must suit the prevailing conditions.

• Take into account easy access for cleaning and maintaining the fan.

• Before installing the fan, make sure the safety distances are maintained compliant with EN ISO 13857 or in household equipment according to EN 60335
  – If the mounting height (danger area) above the reference plane is greater than or equal to 2700 mm and is not reduced by auxiliary means such as chairs, ladders, working platforms or floor space on vehicles, a guard grille is not necessary on the fan.
  – If the fan is located in danger zone, then the manufacturer or operator shall ensure that hazards shall be prevented by appropriare protective constuctions which meet the requirements to EN ISO 13857.

• Tighten the fastenings with the specified torques.

• Drilling chips, screws and other foreign bodies must not be located inside the device! Before the first switch-on, remove any items that may be present (drilling chips, screws and other foreign objects) from the intake area – risk of injury from any objects that may fly out!

• For fans, the alignment must be adhered to during operation, e.g. if this is indicated by “Oben/Top”.

WARNING
Parts of the rotor or the entire rotor coming loose in case of a fault (e.g. excessive vibrations) can result in personal injury and material damage.
Use guard grilles or suitable design measures for critical applications (e.g. refrigerating systems with refrigerant subject to the ordinance on hazardous substances).

4.2 Permissible position of the mounted frequency inverter
Only a horizontal position of the device is allowed, because only in this position specified housing protection class IP54 is ensured. 4.3 Erecting the equipment Design ER
Use screws, for example, of strength class 8.8 according to DIN EN ISO 4014 to fasten the fan.
Secure the screws with a suitable screw lock.
Tighten the fastenings with the specified torques ( Table).
After an operating time of approx. 1 hr. re-check the torque of the screwed connection with the necessary MA.

Permissible tightening torques MA

Thread size| M6| M8| M10
Property class 8.8, friction coefcient µges = 0.12| 9.5 Nm| 23 Nm| 40 Nm

Ensure that the clearance (gap) “a” see fig. between the fan impeller and the stationary housing section is constant. Distortion due to uneven surface may lead to fan failure.
Information

• Every screwing case is different. If the strength class of the screws differs from strength class 8.8, you must determine the adapted tightening torque by appropriate screw tests.

• Structure-borne noise decoupling of the complete centrifugal fan is recommended to avoid transmission of disturbing vibrations. (Spring or damping elements are not usually parts of the standard scope of supply). The assignment of the spacing dimensions of the damping elements can be taken from the catalogues on our home page under www.ziehl-abegg.de in the section Download – Ventilation and Control Engineering.

• Erect in the open air only if this is expressly mentioned and confirmed in the ordering information.
  There is a risk of damage to the bearings if the fan remains stopped in a moist environment. Avoid corrosion by suitable protective measures. Roofing is required.

• Corrosion is possible at the cutting edges on sendzimir galvanised parts.

Warning

• Connect all contact points securely to the foundation or plant. If not fastened sufficiently, there is a risk of the fan tipping over or coming loose – danger of injury!
• The screwed connection that connects the impeller to the hub may never be loosened for any work on the fan! The impeller and hub form a commonly balanced assembly which may only be disassembled and installed as a complete unit. Merely loosening this screwed connection can lead to imbalance and therefore to vibrations even if the screws are connected again correctly before recommissioning!
• Blocking or braking the fan by, say, pushing objects into it is forbidden. This leads to heated surfaces and damage to the impeller.
• Making your own alterations/conversions on the fan module is unacceptable – safety risk!
• Please note the following for all types of centrifugal fans:
  – Avoid structural damage or stress with installation. Make sure the surface is flat and even.
  – Add-on parts (depending on the design: flanges, fastening brackets, frames, rails, support plates, etc.) must lie flat on the contact surfaces.
  – Do not use force, do not lever, do not bend.
  – Do not bend fan roller or fan wheel and blades – imbalance!
  – Important: Deformations and misalignments must not result in the striking or grinding of rotating parts!

4.4 Optimal installation distances according to for RH../ ER../ GR.. fans

• Impeller blade external-diameter : Ø DSa
• Distance on suction side: LA ≥ 0.5 x DSa *
• Distance on pressure side: LD for C/Cpro ≥ 1 x DSa, LD for ZAbluefin ≥ 0.8 x DSa
• Housing wall distances: A = 1.8 x DSa (A = B)
• In the case of disturbance flow (per example curved pipe at the suction side, flaps etc.) LA ≥ 1 x DSa

4.5 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to operate the motor/fan for at least 2 hours every month at 80-100 % of maximum speed to remove any moisture that has penetrated inside.
4.6 Connection cable & junction box
Information
In demanding environments (wet rooms, outdoor installation), connecting cables must have water draining pipe elbows. If a terminal box is mounted near to the fan, this must be installed lower than the mounted PMIcontrol to ensure that water cannot penetrate through the connecting cables.
4.7 Cable inlet
Warning
Only use lines which can guarantee a permanent seal around the cable glands (pressure-resistant, dimensionally-stable, round-centred jacket; e.g. by means of gusset filling)! Lines with filling fleece are not permissible because moisture can penetrate due to the capillary effect!
Remove the terminal compartment cover. All 6 cable entry points are in a sealed condition at delivery (each 3 on long side). Remove plastic fastener depending on the need and insert appropriate cable glands (not in scope of delivery). The manufacturer’s specifications for tightening torque and sealing area must be observed! Entry points that are not used must remain sealed!
Insert cables properly and ensure tightness of the cable glands.
Attach the cover of terminal compartment again carefully after connection (see Electrical Installa-tion).Cable inlet (locking screws made of metal)

The connection must be fused depending on the used cable, the type of routing, the operating conditions and according to the standards applicable on site. The specification for the maximum admissible line fuse of the device must be observed (see technical data).
Possible components for the line protection (recommendation):

• Safety fuses of operating class gG (whole range fuse cartridges for general applications according to EN 60269-1).
• Line protection switch with characteristic C (according to EN 60898-1).

5.4.4 UL note: Short-circuit protection for attached frequency inverter
Short-circuit protection for branch circuits (NEC, CEC)
Danger due to electric current
This power conversion equipment is suitable for connection to electric circuits that cannot supply more than a certain symmetrical current effective.
Please note the additional information under appendix / UL specifications / UL: Short Circuit Current Rating.
5.4.5 Leakage current, securely attached, protective earth conductor
Danger due to electric current
The maximum leakage current depends on the type of device and the connected mains voltage (see Technical Data). With regard to fixed connection and the type of PE conductor connection, the specification for the leakage current must be observed under consideration of the locally valid standards (for Europe see EN 50178 Section 5.2.11 or 5.3.2.1 etc.).
Minimum cross-section for PE conductor for fixed connection = 1.5 mm2!
5.4.6 Operating in IT-System
The described version is intended for use in the IT system, please note the following points.
Danger due to electric current

• In the IT-System the neutral point of voltage supply is not grounded; in the case of a short-circuit between a phase (e.g. L1) and protective earth PE becomes the protective earth potential = phase.
• Between the mains connection of the device and the protective earth PE is in no case a higher voltage permissible than the indicated line voltage of the device!
• Capacitors are installed between the housing potential and the intermediate circuit to reduce radio interference voltages. This must be considered for the choice of insulation monitoring device!

5.4.7 Operation in Grounded Delta System
A device must be selected which allows operation on the existing network type. In Delta System with earthed line phase the maximum voltage between a phase and the protective earth is as high as the voltage between two phases.
In the versions described here, the specified voltage supply (see Technical Data) is permitted at the maximum between the mains connection and the PE con- ductor and they are therefore suitable for use in a Grounded Delta System!
5.5 Systemas with residual-current-operated protective device
Danger due to electric current
For an installation of r.c.d. protection, it shall be observed that this must be of “universal-current sensitivity” (type B). In accordance with EN 50 178, Section. 5.2. other types of current-operated protective devices may not be used. To ensure as high a degree of reliability as possible, we recommend a tripping current of 300 mA.
Residual current circuit breaker (type B)

5.6 Motor protection
Motor protection is provided by the temperature sensors installed in the motor “ TP” (PTC).
When a connected temperature sensor responds or there is an interruption between the two terminals “TB/TP” the device switches off and does not switch back on.
Relais “K1” is de-energized, terminals “13” – “14” interrupted. The signal lamp flashes in code |15| ( Diagnostics / faults).
Switch back on after the drive has cooled down, i.e. in case of a connection between the terminals “TB/TP”, by switching the line voltage off and back on
5.7 Analog input “E1” for setting fan speed
The device has an analog input for setting the fan speed. Connection “E1” / “GND” (Analog In 1).
The internal jumper “E1.1” is factory set in the position for a 0…10 V or PWM speed setting signal.
For a 0…20 mA signal the plug “E1.1” must be replugged.
Danger due to electric current

• Do not replug the jumper under voltage, observe the safety instructions!
• Make sure the signal has the correct polarity!
• Never apply line voltage to analog inputs!

Possibilities for speed setting

0…10 V (factory setting)
Control via external setting signal 0…10 V
or
Speed setting by external potenziometer (10 kΩ) at terminals “+10 V” and “GND” pick of-off at terminal “E1”Diagram setting signal and motor speednM Motor speed
100 % Rated speed
Analog In 1 Speed setting signal 0…10 V / 0…100 % PWM
The motor always starts with at least 10 % of the rated speed as soon as a speed setting signal above 0 % is applied (a lower speed is not possible in principle). The motor stops at 0 % setting signal.
Between 1 % and 10 % setting signal the speed stays at approx. 10 % rated speed providing that the setting “Min. speed ”is “0” rpm (adjustable by auxiliary modules).
5.8 Output voltage 10 V
Voltage supply e.g. for speed setting by external potentiometer.
Connection: 10 V – GND, max. load see Technical data und connection diagram.
Warning

• NEVER connect the voltage outputs of several devices together!
• NEVER connect voltage outputs in the device to each other!

5.9 Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices e.g. a sensor (max. current load see technical data).
In case of overload or short circuit (24 V – GND), the external power supply is shut down (multi-fuse).
The device performs a Reset and continues operation.
Warning

• Never connect the voltage outputs of several devices together!
• Never connect voltage outputs in the device to each other!

5.10 Digital input “D1” for enable (device ON / OFF)
Electronic switch off via floating contact at terminals “D1” – “+24V” (input resistance and voltage range see Technical data).
Function factory setting for “D1”:

• Device “ON” for closed contact.
• Device “OFF” with opened contact.

Activation via floating contacts, a low voltage of approx. 24 V DC is connected.
Danger due to electric current

• No disconnection (no potential isolation in accordance with VBG4 §6) in remote control of the device!
• Never apply line voltage to the digital input!

5.11 Relay outputs “K1”
An external fault indicator is available over the potential-free contact of the built-in relays (max. contact rating Technical data and connection diagram).
Function factory setting for “K1”:

• For operation the relay is energized, connections “13” and “14” are bridged. For fault the relay is de- energized ( Diagnostics / faults).
• When switching off via enable (D1 = Digital In 1), the relay remains energized.

5.12 Status output “OC” (Open-Collector)
Depending on the operating state of the device, the output “OC” is switched to GND potential for a certain number of pulses (output available depending on the model).
The status of the device can be displayed by this digitally coded signal.
Explanation of flash codes see Diagnostic / Status Out with flash code.

Wiring with external LED
With the output voltage “+10 V” a standard LED / low-power LED can be controlled by using a pull-up resistor.
This lights when the output “Status Out OC” (OC = Open-Collector) is on GND potential.
The details of which pull-up resistor needs to be used depend on the specification on the LED that is used. Display by LED in 5-step potentiometer type ZSG-5 (Part.-No. 349073)
In the case of the speed setting via the 5-step potentiometer, the status display can be done via the integrated LED (for connection see operating instructions ZSG-5). 5.13 Potential at control voltage connections
The30connections30for the control voltage (< 30 V) relate to the common GND potential (exception:
relay contacts are potential-free). There is a potential isolation between the connections for the control voltage and the PE conductor. It must be ensured that the maximum external voltage at the con-nections for the control voltage cannot exceed 30 V (between the GND and PE conductor terminals). A connection to the PE conductor potential can be made if required; fit a bridge between the GND terminal and the PE connection (terminal for shield).
5.14 Option add-on modules An additional module can be retrofitted in the slot provided if required (mounting operating instructions of the additional modules).
The range of additional modules is constantly being extended and adapted to market requirements.
The currently available additional modules can be requested from ZIEHL-ABEGG.

Parameter memory ZAstick

6.1 Notes / Safety
ZAstick is a plug-on parameter memory on which all the necessary inverter settings of the respective fan are stored. This enables fast and simple commissioning and energetically and acoustically optimal operation of the fan.
With PMblue and AMblue fans the ZAstick is already in the slot provided in the terminal compartment of the inverter upon delivery. I.e. these products are pre-programmed at the factory! Opening the inverter to plug in or unplug the ZAstick is only allowed with the power line switched off and after waiting at least 5 minutes (see safety instructions)! The following information or presettings can be found on the stick:

• Max. operating point related to the fan (e.g. max. speed)
• Functions of the signal inputs and signal outputs.
• Extended motor data (not changeable!)

6.2 Function
After the inverter is supplied with voltage, it checks whether there is a ZAstick in the slot provided.
If a ZAstick is detected, the inverter searches for matching data records, lads these and saves them internally as a factory setting. The procedure lasts a few seconds and is ended with a single flashing code of the status LED ( table).
Information
This installation procedure already takes place prior to delivery for PMblue and AMblue fans.
The stick can then be left in the slot or removed at any time. However, it is recommended to leave it plugged into the device to avoid losing it.
Warning
It is not allowed to use a ZAstick that is intended for another fan!
The fan could be parametrised with a speed which exceeds the maximum permissible speed of the fan impeller! This can damage or destroy the impeller!
Status LED frequency inverter

Information

• If there are already data records on the frequency inverter, these will be overwritten when the operating voltage is applied when using another ZAstick!
• User settings which were made, for example, with an auxiliary module, remain stored in the frequency inverter.
• The factory setting can be restored by entering a PIN. A communication module is required for this; the parameter storage medium ZAstick must not be plugged into the slot.

6.3 Designation
The printed number and the data matrix code on the ZAstick correspond to the confirmation number of the fan.
The identical number can be found on the fan rating plate so that a correct assignment is ensured.
6.4 Transfer of parameters sets
If the frequency inverter has to be replaced, due to a defect for example, the ZAstick is plugged into the new, unparametrised frequency inverter.
The new frequency inverter loads the necessary parameters in the first-time commissioning and is immediately ready for use.

Commissioning

Warning

• During commissioning, unexpected and hazardous conditions can arise in the entire installation due to defective adjustments, defective components or incorrect electrical connections. Remove all persons and objects from the hazardous area.
• Do not start the fan until all safety instructions (EN 50110, IEC 60364-1)have been checked, the fan is out of range (EN ISO 13857)and danger can be ruled out.
• A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.

7.1 Before first-time start-up
Observe the following points before the initial start-up:

1. Installation and electrical connection have been properly completed?
2. Has any leftover installation material and other foreign material been removed from the fan area?
3. That safety devices -if necessary- are mounted (EN ISO 13857)?
4. The impeller is out of reach?
5. Are the drain holes (as far as available) open or respectively closed according to the suitable installation position?
6. Connection data complies with the specifications on the rating plate?

7.2 During start-up
Observe the following points during start-up:

1. Check the direction of rotation, see rotation direction arrow on the fan blade, impeller base plate, support plates on suction side or rating plate.

2. Ensure even, low-vibration running. Significant vibrations due to uneven running, e.g. due to transport damage or improper handling, can lead to damage and subsequently to failure.

3. ZIEHL-ABEGG SE fans are delivered balanced in compliance with DIN ISO 21940-11 for the corresponding fan category as set out in ISO 14694. After installation, check the fan for mechanical vibrations and resonances in accordance with ISO 14694. If the limit values for the corresponding fan category are exceeded during start-up, see section f, the entire system must be checked and the vibrations reduced.
   System start-up is not allowed until the limit values are observed.
   a. Time frame for checking the vibration values:
   • On a new system or a new device
   – If necessary in the event of factory acceptance.
   – At the installation site at the time of proper start-up of the system or device at the latest.
   b. Measuring device and sensors:
   • It is recommended that measurement is performed with a resolution based on the r.m.s. (root-mean-square value), a measurement interval of 1 s and a ramp- up time of 180 s.
   • At the same time, precisely timed measurement of the speeds is necessary so that the vibration values can be assigned to the speed.
   • Perform the measurement over the entire fan speed range.
   • Perform the measurement in all 3 axes, see Point c.
   c. Direction of vibration amplitude d. Measuring point on fan
   • Bei ECblue fans mit external rotor motors
   – At the stator fixing screw opposite the cable inlet, see arrow.• On AMblue and PMblue fans with internal rotor motors
   – At the fixing screw for the A-side bearing bracket, see arrow.
   e. The fans are classified in the following categories in accordance with the standard and the power consumption: • ≤ 3,7 kW in BV-2
   • > 3,7 kW in BV-3
   f. Limit value r.m.s. for vibration amplitude during start-up within the customer operating speeds:
   • Max. 5.6 mm/s, in compliance with ISO 14694 Table 5 Start-up / BV-2.
   • Max. 4.5 mm/s, in compliance with ISO 14694 Table 5 Start-up / BV-3.

4. For example, vibrations in the system may have the following causes:
   • Transport and handling of the fans can lead to a change in the balance of the fan.
   • The air feed and resulting turbulence, e.g. obstructions, deflections, branches, flaps.
   • Operation at a prohibited fan operating point, e.g. demolition operation in a flat characteristic curve range.
   • Insufficiently rigid fan mounting surfaces, e.g. mounting walls.
   • Vibration transmitted by adjacent components, e.g. compressors, adjacent fans.
   • Flow-related influences from adjacent fans.

5. If resonance vibrations occur that cannot be prevented by the design, it is possible to mask out certain speed ranges for the operation area of the fan, see Motor setup. Passing through this resonant range as quickly as possible is allowed. Operation of the fan in the resonant range is not allowed.

8.3 Brake function and behaviour in rotation by air current
The PM motor of the fan is operated without a position encoder. In principle, the fan impeller should stand still when starting and must not turn in the wrong direction.
At applied line voltage, enable and a setting signal above “0”, the speed control is active and the speed is stable even under load fluctuations.
Brake function

• If the line voltage is switched on while the fan is rotating in reverse (wrong direction), e.g. by suction or draught, the fan is decelerated. However, under some circumstances it might not be possible to bring the fan to a standstill and start it with the correct direction of rotation.

• If the motor is not controlled with line voltage applied, i.e. without enable or with enable with setting signal “0”, the brake function becomes active to hold the motor until start (holding brake).

• The brake function also becomes active to bring the fan to a standstill if this is rotating without control in the correct direction with a speed of below 4 % of the rated speed. If the braking current exceeds an internal limit, the braking process is interrupted to protect the motor and inverter.
  Further braking attempts are made after a short time.

• When driven in correct direction of rotation and with enable with a setting signal above 10 %, the motor is started whilst the fan is rotating.

Behaviour in strong drive in reverse direction (e.g. suction)
The braking effect with applied line voltage is limited, strong reverse acting forces can lead to rotational movement despite the holding brake.
From a certain level (fan-dependent) it is no longer possible to start the fan in the correct direction.
Information

• Do not switch off the line voltage so that the braking function can prevent rotation of the fan in reverse (wrong) direction and safe starting is possible.
• If the application requires safe starting after switching on the line voltage, too strong an air current (suction effect) in reverse direction must be prevented by suitable measures.
• Special settings are possible which can lead to deviations from the above functional description.

Service work

9.1 Maintenance/servicing
Warning

• Please read the Safety instructions chapter before working on the fan!

• Before working on the fan, this must be disconnected from the power supply and secured against switching back on!

• No maintenance work at running fan!

• Allow maintenance work to be carried out by trained specialists only.

• Any faults detected in the electric system/modules/operating equipment must be corrected immediately. If these faults are not corrected, the device/system is potentially very dangerous. The device/system must therefore not be operated when it is faulty.

• Wear safety clothing / shoes and cut-resistant safety gloves when handling!

• Please observe the safety regulations and the worker´s protection rules by all maintenance and service work (EN 50 110, IEC 60364-1).

• Fuses must always be only replaced; never repaired or bridged. The specifications for the maximum series fuse must always be adhered to (see Technical data). Only fuses cited in the electrical circuit diagram may be used.

• Generator operation can produce dangerous voltages (see safety instructions)!

• Keep the airways of the fan free – danger because of objects dropping out!

• Watch out for vibration free motion!

• The impeller is subject to natural wear depending on the area of application and the conveying medium. Deposits on the impeller can lead to imbalance and damage (danger of permanent fracture). The impeller can burst!

• If highly aggressive media for which the product is not suited are conveyed, the severe corrosion may result in the impeller breaking. Any impellers corroded in this way must be replaced immediately.

• Deposits on the motor, particularly on the cooling vanes and in recesses on the rotor, can lead to reduced cooling performance and the motor switching off prematurely. For this reason, remove deposits quickly (see chapter: Cleaning).

• Maintenance interval in accordance with the degree of contamination of the impeller!

• Check the fan at regular intervals (recommendation: every 6 months) for mechanical oscillations.
  Observe the limits specified in ISO 14694 and, if they are exceeded, implement remedial measures (e.g. rebalancing by specialist staff).

• Check the impeller, in particular the weld-seams, for possible cracks.

• Repair, e.g. by welding is prohibited!

• Bolted-on impellers and/or wings may only be replaced by authorised ZIEHL-ABEGG SE staff. The manufacturer shall not be liable for damage caused through improper repair work.

• Please consult our service department with regard to changing the bearing as for all other damage (e.g. to the coil).

• Regular inspection and possibly cleaning is necessary to prevent imbalance and blockage of the drain holes due to ingress of dirt.

• When opening cable glands on the fan / motor, check the condition of the threaded connections and seals. Always replace defective or brittle threaded connections and seals.

Information
Confirmation number for inquiries or in service cases see rating plate.
State the additionally engraved confirmation number (available depending on the motor build) if the rating plate is no longer legible. This can be found under the affixed rating plate or on the stator flange (in external rotor motors) depending on the motor size.
9.2 Cleaning
Danger due to electric current
Voltage supply for fan must be interrupted and secured against restoration!
Clean the fans`s flow area.
Warning

• Do not use any aggressive, paint solvent cleaning agents when cleaning.
• Make sure that no water gets inside the motor and the electronics (e.g. by direct contact with seals or motor openings), observe protection class (IP).
• The drain holes (if available) corresponding to the installation position must be checked for free passage.
• In case of improper cleaning work, no warranty is assumed regarding corrosion formation / paint adhesion for unpainted / painted fans.
• To avoid accumulation of moisture in the motor, the fan must be operated for at least 1 hour at 80% to 100 % of the maximum speed before the cleaning process!
• After the cleaning process, the fan must be operated for at least 2 hours at 80 to 100 % of the maximum speed for drying purposes!

10.2.2 UL: Overload protection
The devices are equipped with a solid state motor overload protection and a solid state short circuit protection.
The solid state motor overload protection protects the motor under overload conditions by reducing current flow to the internal motor output terminals. This protection is achieved through algorithms based on I2t of the current of the motor.
The overload protection circuitry is optimally configured to the specific motor and the specific final application of the integrated variable speed drive. This is typically 100 % of the full-load current of the motor.
The solid state short circuit protection acts to suspend current flow to the internal motor output terminals upon sensing output current and DC-link voltage. The protection of the motor is comprised of hardware and firmware.
10.2.3 UL: Short Circuit Current Rating
The devices are suitable for use in a circuit capable of delivering no more than 30/100 kA RMS symmetrical (see also information sign on product). Details can be found in the following table.
The fusing for the short-circuit protection must comply with the requirements in UL248 and additional to CAN/CSA C22.2 No. 248.
Tests were made with RK fuses without semiconductor protection:
