Output protection

Output over-voltage protection

typ. 30.5Vdc

max. 32Vdc

In case of an internal power supply defect, a redundant

circuit limits the maximum output voltage. The output

shuts down and automatically attempts to restart.

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 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 fulfill 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.
