Operation of the line connection components via a transformer

Note
If the system fault level is too low, this can result in faults at the integrated infeed of the
SINAMICS S120 Combi Power Modules. It can also cause faults and damage to other
equipment and devices that are connected to the same line connection point as the S120
Combi Power Module.
Note
Using a transformer with the S120 Combi Power Module does not replace the external line
reactor.
