Siemens SINAMICS G150 Operating Instructions Manual page 71

Components and devices that have been voltage tested according to their product standard
may be disconnected during testing.
The SINAMICS cabinet units are voltage tested in accordance with EN 61800-5-1 and are to
be disconnected during this test.
If they cannot be disconnected, input and output terminals must be short-circuited and a
bypass installed. In this case, a DC voltage that is 1.5 times the AC test voltage should be
used for testing.
1) Main circuits are circuits that are electrically connected to the line voltage.
