ground.
Perform the test in Normal Condition (NC) and in two different Single Fault Conditions (SFC):
1) earth open and 2) one of the supply conductors open at a time.
Perform test with normal and reverse polarity.
NOTE: Refer to the instructions delivered with the safety analyzer to perform this test.
NOTE: *The measuring device (MD) represents the network and voltage measuring instrument
and its frequency characters according to IEC 60601-1.
