– 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.
•
Protective measures must be taken against falling parts when mounting with a hanging rotor.
•
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”.

Information
•
Since the concrete bolt or screw varies by customer unit, these recommendations must be checked
for each respective situation.
•
Secure the cable covering against loss after connecting the motor by securing with 2 cable ties.
•
For a version with a square rear wall (design Q), removal of this square plastic plate is prohibited.
