19. DIELECTRIC STRENGTH
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.
We recommend that either the + pole or the – pole 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.

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.
