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 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 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.
