5.4.1 Description
The Control Supply Module (CSM) provides a 24 V DC power supply via the power system
or DC link. In this way, controlled emergency retraction movements can be made in the
event of a power failure, for example, provided that the DC link voltage is available.
The supply voltage is a PELV (protective extra low voltage). The earth potential for the
protective conductor system is connected in the Control Supply Module.
Input voltage range: 320-550 V
