1. Screw the protective ground at the provided locations in the cabinet to the appropriate
connection with the ground symbol.
Note
Connect the motor cables first and then the power cables.
2. Connect the infeed cable to the supply-system connection busbar.

3. Screw the individual phases of the motor cable to the connections below of the output
phases.
Observe the following connection sequence of the conductors: 1U1, 1V1, 1W1 and 2U1,
2W1, 2V1
Direction of motor rotation
Connect asynchronous machines with clockwise phase sequence (looking at the drive shaft) to
the drive as follows:

In contrast to the connection for the clockwise phase sequence, two phases have to be
reversed with a counter-clockwise phase sequence (looking at the drive shaft).
Note
If an incorrect phase sequence was connected during the cable installation and it cannot be
corrected by a subsequent swapping of the motor cables, you have two possibilities:
● Change the phase sequence by entering a negative setpoint.
● Change the phase sequence with the drive parameterization.
Note
Interconnect the windings for motors that can be operated in star-delta correctly. To do this,
read the motor documentation. Observe the required isolation voltage for the operation of the
drive.
