8.6 Control Supply Module CSM

Observe the connection sequence

If a selectively tripping, AC/DC-sensitive RCCB is used for the drive line-up, the Control

Supply Module must always be connected to the line supply downstream of this circuit

breaker. Otherwise, the residual current operated circuit breaker will trip erroneously if the

direct-current component is asymmetrically drawn 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 red 24 V connector from the

accessories pack provided must be inserted under all circumstances. 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 red 24 V connector).
