Dielectric strength
The output voltage is earth-free and has no ohmic connection to earth. Type and component tests are
carried out by the manufacturer. Field tests can be performed in the field using suitable test equipment that
ramps up the voltage with a slow ramp (2 s rising and 2 s falling). Connect all input terminals and all output
poles to each other before performing the tests. During the test, set the cut-off current to the value shown in
the table below.

When checking the input to DC-OK, make sure that the maximum voltage between DC-OK and the output
is not exceeded (column D). When performing the test, we recommend connecting the DC OK contact pins
and the output contact pins.

To meet the PELV requirements according to EN 60204-1 section 6.4.1, we recommend connecting either
the positive pole, the negative pole or another part of the output circuit to the protective conductor system.
This avoids situations in which the load starts unexpectedly or cannot be disconnected if an unnoticed earth
leakage occurs.
