touch due to their installation conditions (e.g. in line with the air ductwork), no direct touch guard is required if the installation conditions provide an equivalent level of
safety. Note that the fan user is liable for compliance with current safety standards and may be held liable for accidental injury or death caused by failure to provide the
required safety equipment.
Electrical connections
•
Electrical connections and commissioning of the fan shall only be completed by qualied professional electricians.
•
Always follow the applicable standards, safety regulations and technical requirements specied by the power company!
•
The power supply line for the fan requires a multi-pole circuit breaker / isolation switch with a minimum contact break gap of 3 mm (ref. PN-EN 60335-1)!
•
The mains system, voltage and frequency must match the nameplate ratings of the fan.
•
Fans with the stop delay timer: the maximum voltage limit on terminal T to initiate the stop delay time countdown or start the fan is approx. 130 V AC.
Dimensions
The dimensions of specic fan models are shown in Fig. 6.
MAINTENANCE AND CLEANING
Servicing and maintenance
•
Use protective footwear and gloves during maintenance!
•
During all maintenance and servicing works the electrical and OHS regulations (PN-IEC 60364-3) must be observed.
•
Before servicing the fan, isolate it from the mains voltage with the circuit breaker. Secure the circuit breaker against inadvertent operation!
•
The fan ductwork must be clear of foreign bodies: hazard of injury by objects blown out at a high speed!
•
Do not attempt any maintenance when the fan is running or at live voltage!
•
If excessive vibrations are felt or heard, have the technical inspection carried out by a qualied electrician.
•
The maintenance intervals depend on the actual contamination of the fan rotor and must not be longer than 6 months!
•
Check the fan rotor for cracks.
•
The manufacturer shall not be liable for any damage resulting from unprofessional repairs.
•
For equipment where engines with ball bearings have been used with “lifetime lubrication”, the engine does not require lubrication.
