Below is suggested wiring diagram for connecting the fan to the mains electrical supply. The
diagram is however subject to local laws and regulations and should be modified if necessary
to comply with such laws and regulations.

1 = Overload protection switch
2 = Circuit breaker
3 = Fan motor
NOTE Failure to operate the fan with an overload protection device will render the
motor guarantee null and void. Such motor overload protection devices can be
ordered from Munters and be supplied with the fans.
NOTE
The connection cable must be completely extracted from the fan housing in
order to avoid being damaged by moving parts.
To avoid excessive voltage drop, which can be harmful to electrical motors, care must be
taken as to the thickness of cables used as well as the distance (D) from the main electrical
enclosure to the motor. In the Table below are the maximum allowable distances.
