3.3.4 Connecting the fan
Instructions relevant to safety
Please observe the following safety instructions relating to connecting a fan:
CAUTION
Provide a protective circuit that prevents the main motor from being switched on when the
fan unit is not in operation.
CAUTION
Please note that the separately driven fan unit is only suitable for the direction of rotation
shown by the direction-of-rotation arrow.
The fan must not be operated with the wrong direction of rotation as this could lead to the
motor being destroyed.
Note
The direction-of-rotation arrow and the direction of movement of the fan impeller are
indicated on the rear side of the blower.
If necessary, switch the direction of rotation by swapping over two phase conductors in the
terminal box.
Connection
Connect up the fan in the terminal box of the fan unit.
