Connect the Motor Fan
Cooling of forced-ventilated motors (design IC416) is done via an electrical
fan which is mounted and separately connected onto the motor. It is operated
with 400 V (star connection) or 230 V (delta connection). The fan is factory-
adjusted designed for 400 V.
The electrical connection is done by means of fan terminal box on the fan
housing (see
fig. 6-2 "Connection Overview" on page 47
). Additionally, the
connection scheme is figured within the lid of the fan terminal box and shows
the connection for 230 V and 400 V. The interconnection is factory-adjusted
designed for 400 V.
