17. Dielectric Strength
The output voltage is oating and has no ohmic connection to the ground. Type and factory tests are conducted by
the manufacturer. Field tests may be conducted in the eld using the appropriate test equipment which applies the
voltage with a slow ramp (2s up and 2s down). Connect all phase-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 fulll the PELV requirements according to EN 60204-1 § 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.
