The power module provides the required power for the control modules and the
motor. The power module is selected depending on the motor and control mo-
dule.
2.5.2 Connecting the power modules
The power module is grounded via the PE connecting studs.
The power module must be mounted on a grounded, low–ohmic conductive
mounting surface and be connected with this through a good electrical connec-
tion.
The power supply is realized from the DC link buses.
