ELECTRICAL CONNECTION

Electricity warning (hazardous voltage)!

Failure to observe the hazard may result in death, injury or damage to property.
Before performing any work on conductive parts, always disconnect the unit completely from the electricity supply and make sure that it cannot be switched back on again.

The electrical installation may only be carried out by qualified electricians in compliance with the installation, operating and maintenance instructions and the applicable national regulations, standards and guidelines:

ISO, DIN, EN and VDE specifications, including all safety requirements.
Technical connection conditions.
Safety at work and accident prevention requirements.

This list does not claim to be complete. Requirements should be applied under one‘s responsibility.

The electrical connections must be made as shown in the corresponding wiring diagrams and terminal diagrams.
The type of cable, size of cable and method of laying should be determined by an authorized electrician.
Low and extra-low voltage cables should be laid separately.
If no repair switch is integrated into the device, an all-pole main disconnecting switch with min. A 3 mm contact opening must be provided in the supply line.
Use a separate cable inlet for each cable.
Any cable inlets that are not used must be sealed so that it is airtight.
All cable inlets must have strain relief.
Create equipotential bonding between the unit and the duct system.
Check all protective measures after the electrical connection work (earthing resistance, etc.)
Motor current and motor power must not exceed the values stated on the motor nameplate. The specified max. fan speed must never be exceeded, otherwise the motor and fan will be destroyed by this overload and dissolved or flying parts can destroy other components.

While in continuous operation, voltage-controllable fans are allowed to function only with at least half of the nominal voltage. If this is not upheld, the motor unit may suffer damages.

Unit supply cable/Electrical connection/wiring diagram

Connect the main supply cable as shown in the wiring diagram. For the dimensioning of the line, observe the unit‘s rating plate and the relevant guidelines. Appropriate protection with correctly dimensioned automatic safety breakers (circuit protection breakers) must be provided.
The device must be connected according to the wiring diagram. For fans that are controlled by external control devices, the corresponding operating instructions of the manufacturer must be observed.

ruck-DVA...E.P-31-Roof-Fan-For-Exhaust-Air-Fig-17

Thermal motor protection
During operation, electric motors heat up. Under certain circumstances (excessively high ambient or fluid temperatures, heavy contamination, etc.), the motor temperature may exceed the safety limit of the electrically isolated parts. To avoid engine damage, various types of temperature monitoring are possible, of which at least one must be installed on-site. (Exception: fans with thermal contacts integrated into the motor current) Applies for versions with led-out thermal contact: No warranty in case of a not-connected Thermal Contact. Damages caused by overheating will not be considered.

COMMISSIONING

Commissioning by trained technical personnel may only be performed after any risk has been ruled out. The following checks should be performed by the installation and operating manual and the regulations in force:

Correctly sealed installation of the unit and duct system.
Check the duct system, unit and medium lines, if present, remove any foreign bodies if necessary.
The intake opening and inflow into the unit must be clear.
Check all mechanical and electrical protection measures (e.g. earthing).
Voltage, frequency and type of current must correspond with the rating plate.

MAINTENANCE AND CLEANING

Servicing, troubleshooting and cleaning may only be performed by specialised personnel by this installation and operating manual and the regulations in force.

Make sure that no connections or components are loosened unless the device is disconnected from the mains. Make sure that the equipment cannot be switched back on again.
Individual components must not be interchanged. For example, the components intended for one product may not be used for other products.
The regular maintenance and care of our devices is designed to ensure proper function, value retention and avoidance of damage. Keep a maintenance log.
Perform the specified maintenance on the unit at the specified intervals.

Our devices require little maintenance when operated properly. The following work should be performed at regular intervals, according to health and safety regulations:

Check the operation of the control system and safety devices.
Check electrical connections and wiring for damage.
Remove any dirt from the fan impeller or impellers and from inside the fan housing to prevent any unbalance or reduction in output.
- Do not use aggressive or easily flammable products for cleaning (impellers/housing).
- Preferably only water (not flowing water) or mild soapsuds should be used.
- The impeller should be cleaned with a cloth or brush.
- Never use a high-pressure cleaner.
- Balancing clips must not be moved or removed.
- The impeller and fittings must not be damaged in any way.

Before putting the unit back into operation after maintenance and servicing work, carry out a visual inspection as described in section 11. and 12.

LIFETIME AND DISPOSAL

Product life

The motors are equipped with maintenance-free, permanently lubricated ball bearings. Under normal operating condi-tions, the expected lifetime is about 30,000 operating hours.
The information given here depends strongly on the respective field of application as well as the environmental condi-tions. We recommend replacing these fans after reaching about 30,000 operating hours or 5 years.

Decommissioning and disposal
When disassembling, parts under voltage are exposed, which can lead to electric shock when touched. Before dismantling, disconnect the fan from all poles of the mains and secureit against being switched on again!

Parts and components of the device that have reached their lifetime, e.g. due to wear, corrosion, mechanical stress, fatigue and/or all other, not directly recognizable effects, must be disposed of professionally and properly after disassembly by national and international laws and regulations. The same applies to excipients in use such as oils and fats or other substances. The conscious or unconscious reuse of used components such as e.g. impellers, rolling bearings, and motors. etc. can lead to a risk to persons, the environment as well as machinery and equipment. The applicable local operating regulations must be observed and applied.
