● To connect the motor fan, the fan connector has to be
opened and closed.
● Electric connection may only be established by specialized
staff. Comply with the safety instructions.
● The tightness of the connector housing may not be reduced.
● Motor protective switch and electric fuse protection are se‐
lected by the machine manufacturer. Please observe the
regulations in the country of installation.
● The connector for connecting the motor fan is included in the
scope of delivery and is located on the motor fan.
The following coolant ports can be selected for motors with liquid cooling:
● Coolant port via the connection thread on the motor
● Coolant port via quick couplings
The inlet (IN) and outlet (OUT) can be arbitrarily assigned. The
assignment does not have any effect on the performance data of
the motor.
