16. Protection Features
Output protection Electronically protected against overload, no-load and short-circuits *)
Output over-voltage protection typ. 58Vdc
max. 60Vdc 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.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5mm e.g. screws, small parts
Over-temperature protection yes Output shut-down with automatic restart
Input transient protection MOV (Metal Oxide Varistor)
Internal input fuse T6.3A H.B.C. not user replaceable
*) In case of a protection event, audible noise may occur.

18. Dielectric Strength
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 meet 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 be connected to the protective earth system.
This helps to avoid situations in which a load starts
unexpectedly or cannot be switched off when unnoticed earth
faults occur.
