The output voltage is floating and has no ohmic connection to the ground. Type and factory 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.

To fulfil the PELV requirements according to EN60204-1 § 6.4.1, 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 max. 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.
