Line/Power Connections - Siemens SINAMICS S120 Operating Instructions Manual

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.
