Connection examples

The Control Supply Module is connected to the line supply (3-ph. 380 V AC -10 % to 480 V
AC +10 %) via interface X1 (screw terminals 0.2 to 4 mm
preferably be made without using an isolating device (e.g. contactor).
The Control Supply Module has an internal line filter (Class A for TN systems), and the pre-
charging circuit for the DC link inside the device is electrically isolated from the 24 V supply.
The Control Supply Module also features a current limitation function.
Note
If you use cables with a cross-section of 2.5 mm
24 V 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 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.
