Product overview
3 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.
Caution! 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
ECblue stands for EC fans and motors with maximum efficiency. Highly
efficient, electronically commutated motors with permanent magnets are used
the speed of which is controlled by the integrated controller. 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.
3.3 Temperature management
The service life of devices with power electronics is decisively dependent on
the ambient temperatures. 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 management (power reduction). However, this cannot
provide complete protection in all circumstances. Observe the rated data
particularly the maximum permitted ambient temperature – on the rating plate.
3.4 Note on the ErP directive
ZIEHL-ABEGG SE wishes to point out that, based on the directive (EU) no.
327/2011 of the Commission 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.

4.4 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.
4.5 Motorheating
A continuous power supply is required for safe operation down to the minimum
permitted ambient temperature (see technical data). If the motor is not
operated with an existing power supply (no setting signal, switch off by
enable), the motor heating switches back on automatically at a controller
inside temperature of -19 °C and back off when heated up to -15 °C. Heating
takes place via the motor winding whereby a current is induced which cannot
cause rotation.

control cables must be used when the cable length is longer than 20 m. When
using a shielded cable connect the shielding to one side only, i.e. only to
the signal source with the protective earth (keep cable short and with as
little inductance as possible!).
5.5 Voltage supply
5.5.1
Mains voltage
Danger due to electric current
· It must be strictly observed that the line voltage complies with specified
on the rating plate and lies
within the allowable tolerance specifications (see technical data).
· Between the voltage supply of the device and the protective earth “PE” is in
no case a higher voltage
permissible than the indicated line voltage of the device!
· Mains connection to: PE, L1 and N. · Caution!
To activate the on current limitation, you must wait at least 90 seconds
after switching off the line voltage before switching back on!
5.5.2
Required quality attributes for the mains voltage
Danger due to electric current The mains voltage must comply with the EN 50160
quality characteristics and the defined standard voltages in IEC 60038!

5.5.3
Line protection fuse 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).
5.5.4
Operating in IT-System
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 connection of the voltage supply of the device and the
protective earth “PE” is in no
case a higher voltage permissible than the indicated line voltage of the
device!
1 ~ types can be used in IT-System in standard version. These may only be used
in 3 ~ IT-Systems if no higher voltage to the “PE” can occur than the
specified mains voltage of the device even in case of a fault to earth of a
mains phase which is not used by the device (of none of the two power
supplies). In order to ensure a trouble free operation in IT-System the “GND”
potential of the control ports have to be connected with the protective earth
potential. As a consequence of these connection must be considered for the
control ports (exception floating relay contacts):
1. Connection only with wires, suitable for mains voltage and surrounding
area. 2. Connection with suitable isolated amplifiers only.
5.6 Systems with residual current protective devices
Whether the use of a residual current protective device (RCD) is necessary or
allowed depends on the design of the low-voltage system on which the device is
to be operated. The assessment whether or which residual current protective
device should be used is the responsibility of the system operator or
electrician commissioned by it.
Danger due to electric current When selecting the tripping characteristics of
the residual current protective device, the possible residual current form of
the power electronics (system with semiconductors) must be observed in
conjunction with the standards and regulations applicable at the place of use.
Design of the power electronics
· The design of the power electronics corresponds to a frequency inverter with
two-pulse bridge
circuit and PFC (power factor correction).
Information To prevent false tripping due to pulse-like charging currents of
the integrated EMC filter, we recommend a rated differential current of 300 mA
for reasons of operational reliability in the case of fixed connection and use
of a residual current protective device.
5.7 Motor protection
Integrated overload protection, preceding motor protection device unnecessary
(max. line fuse see Technical data).
5.8 Voltage supply “10 V DC”
Voltage supply (PELV current source pursuant to DIN EN 60204-1) for external
components, e.g. for ECblue connection box. Connection: “10 V” – “GND” (max.
load see Technical data und connection diagram). During an overload or short-
circuit (10 V – GND), the control voltage (and thus the device) is
disconnected . Automatic start after elimination of the cause of error. It is
not permissible to connect outputs of several devices to each other!

Information
· You must ensure correct connection; i. e. “A(D+)”must also be “connected on
thefollowing devices to
“A(D+). The same applies to “B (D-)”.
· In addition, a “GND” connection must be established, as dissimilar potential
(over 10 V!) will lead to
the destruction of the RS-485 interface (e.g. lightning).
· Pay attention to sufficient distance from powerlines and motor wires (min.
20 cm) · Except the data link “A (D+)”, “B (D-)” the “ID1 – ID2” and the “GND”
connection may no further cable
cores of the data line be used.
· When using the connection box the cable shield of the CAT5 cable is
internally connected to “PE” by
an RC element.
· Another 63 users are connected by a repeater in manual addressing (no
connection of connections
“ID1”, “ID2”).
· If a repeater is necessary and automatic addressing should be carried out,
only the repeater of the
Z-G-1NE type can be used, only it can relay the addressing signal.
· The connections for the automatic addressing “ID1” and “ID2” are not
directly connected electrically
with each other. These may not be bridged; any order of connection is
possible.
Example for MODBUS connection
The data line must be conducted from one device to the next. No other type of wiring is allowed! Always use only two wires of one lead (twisted pair) for the connection.

Shielding The use of shielded cables is normally not needed but offers high protection against electromagnetic interferences, especially high frequencies. However, the effectiveness of the shield depends on careful installation of the line. If shielded cables are used, the shield should be placed at “PE” on at least one side (preferably on the master connection). The occurrence of compensating currents may have to be considered if the shield is contacted on both sides.
Shield connection correct
Shield connection incorrect
When using telephone cable with four cable cores, we recommend the following

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
connections 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).

Commissioning
6 Commissioning
Caution!
· 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.
6.1 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?
6.2 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.

· Bei ECblue fans mit external rotor motors
At the stator fixing screw opposite the cable inlet, see arrow.
Commissioning
· 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.

7.3 Behaviour in rotation by air current in reverse direction
In the STOP state (no release, no preset signal, no voltage supply) the motor
controller does not intervene when the fan turns in the wrong direction (e.g.
due to a draught). If the fan is started (= voltage ON), while being driven in
the opposite direction to that set, the speed is reduced controlled to “0” and
restarted in the set direction of rotation. The higher the speed to be
reduced, the longer this process lasts.
Information Do not disconnect the line voltage if, during an application, this
might result in the disconnected fan being propelled very powerfully in the
reverse direction. This ensures a safe start at all times.
8 Service work
8.1 Maintenance/servicing
Caution!
· 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.
L-BAL-F056-GB 2023/25 Index 006
Part.-No. 00700562-GB 29/36
Assembly instructions ECblue
Service work
· 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.
8.2 Cleaning
Danger due to electric current Voltage supply for motor must be interrupted
and secured against restoration!
Clean the fans`s flow area.
Caution!
· 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!

Ball bearing life
The bearing service life of the motor-integrated ball bearings determined in accordance with the standard calculation method is largely determined by the grease service life F10h and is approx. 30,000 to 40,000 operating hours in standard use, taking into account a temperature and load spectrum. The fan or motor is maintenance-free due to the use of ball bearings with life-time lubrication. Once the grease service life F10h has been reached, it may be necessary to change the bearing. The bearing service life may change compared to the specified value if operating conditions such as increased vibrations, increased shocks, increased or excessively low temperatures, humidity, dirt in the ball bearing or unfavourable control modes are present. A service life calculation for special applications can be created on request.
