Note
To route the power cables from above into the cabinet, remove the cover plate at the top of
the cabinet.
NOTICE
Danger of thermal damage
Inadequately fastened cables at the connection point represent a high electrical transfer
resistance that can cause thermal damage (contact erosion) during operation.
Tighten the screws with the specified torque.
1. Screw the protective ground at the provided locations in the cabinet to the appropriate
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
Direction of motor rotation
Connect asynchronous machines with clockwise phase sequence (looking at the drive shaft)
to the drive as follows:
Table 6-3
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).
