The Control Supply Module (CSM) is connected to the line supply (3-ph. 380 V AC –10 % up
to 480 V +10 %) via the appropriate screw terminals (0.2 to 4 mm
2
). This connection should
preferably be made without using an isolating device (e.g. contactor).
The CSM is protected corresponding to the data provided in the Equipment Manual for
Booksize power units. The CSM has an internal line filter (Class A for TN line supplies), and
the pre-charging circuit for the DC link inside the unit is electrically isolated from the 24 V
supply.
Note
When engineering the line supply of the CSM, it should be noted that the CSM may not be
connected to the line supply after the line module is connected to the line supply. When
charging, this prevents the DC link from being immediately loaded by the CSM.
NOTICE
If a selectively tripping AC/DC-sensitive residual-current circuit-breaker is used, the Control
Supply Module must be connected downstream of this.
