The output voltage is floating and has no ohmic connection to the ground. Type and routine tests are conducted by

the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the

voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before

conducting the test. When testing, set the cut-off current settings to the value in the table below.

Output

We recommend that either the + pole, the – pole or any other part

of the output circuit shall be connected to the protective earth

system. This helps to avoid situations in which a load starts

unexpectedly or can not be switched off when unnoticed earth

faults occur.

B*) When testing input to DC-OK ensure that the maximal voltage between DC-OK and the output is not exceeded (column D). We

recommend connecting DC-OK pins and the output pins together when performing the test.
