Forced ventilation (IC416)
MS2N motors of size 07 and 10 are available as forced ventilated designs. The
designation is done via the feature cooling mode „A“ (230 V / 50 Hz) and
„B“ (115 V / 60 Hz) in the type code.
In case of force-ventilated motors, the energy dissipation is additionally realized
via a fan that is not connected to the motor.
Damage to persons and machines due to draw-
ing in of hairs, clothes or loose objects.
Before you get closer to operating fan units, take protective measures. Do not
wear jewelry, wear tight-fitting clothes and use personal protective equipment
(like a hairnet). Tie your hair back. Otherwise the danger exists that hair will get
ripped out.
The specified nominal data is reached at ambient temperatures of up to 40 °C.
Unhindered drawing in of cooling air and heat dissipation has to be ensured by
minimum distances to the machine environment.

Blowing fans, air flow direction NDE → DE.
Operate fans only in dustfree and dry ambient air. Heated air may not be sucked
in again.
Dirt and contaminants can reduce the flow rate of the fans and result in a ther-
mal overload of the motors. The availability of the system can be increased by
