Connecting To The Infeed - Siemens SINAMICS S120 Equipment Manual

Connecting to the infeed

Description
If an Auxiliary Power Supply Module is not available to supply power to the auxiliary voltage
busbar system or if the Auxiliary Power Supply Module and the Cabinet Modules to be
supplied are installed in different parts of the cabinet and require jumpering, an infeed
Faston plug, for example, can be used to feed power to the auxiliary voltage busbar system.
Establishing the connection
CAUTION
Once inserted, make sure that the plug is neither pushed down nor pulled out during
operation.
A Faston plug can be inserted up to 10 times, after which it loses its contact reliability.
CAUTION
Avoid stripping too much of the insulation on the cable. If possible, the bare cable should
not be visible at the plug. Only approximately 10 mm of insulation should be stripped.
Note
The plug and connection jumpers are correctly inserted when the plug clicks into place.
Make sure that it is secure.
