Control Supply Module (CSM)
9.4 Connection examples
The Control Supply Module also features a current limitation function.
Note
If you use cables with a cross-section of 2.5 mm
side for the following cable types:
• Cables of the XLPE type
• Cables of the EPR type
• Cable with a similar properties and which is thermally stable up to 90 °C
Note
Observe the connection sequence
If a selectively tripping, AC/DC-sensitive residual current operated circuit breaker is used for the
drive line-up, connect the Control Supply Module to the line supply on the drive end of this circuit
breaker. Otherwise, the residual current operated circuit breaker can trip erroneously if the
direct-current component is asymmetrically withdrawn in certain operating states.

Single operation

Within the drive line-up, the Control Supply Module must be connected to the drive line-up via
the DC link busbars as well as the 24 V busbars. The 24 V connector from the accessories pack
must always be inserted. The DIP switch on the Control Supply Module must be set to "single
mode" The connection can be established as shown below.
The supply for other 24 V loads outside the drive line-up using additional Control Supply
Modules, whose outputs are not connected in parallel, must be realized using the 24 V terminal
adapter (do not insert the 24 V connector).
