The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
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.

It is recommend that either the + pole, the – pole or any other part
of the output circuit shall be connected to the earth/ground
system. This helps to avoid situations in which a load starts
unexpectedly or can not be switched off when unnoticed earth
faults occur.
