17. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
Output over-voltage protection typ. 34Vdc
max. 36Vdc
In case of an internal power supply defect, a redundant
circuitry limits the maximum output voltage. The output
shuts-down and automatically attempts to restart.
Output over-current protection Electronically limited See Fig. 8-1
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) and active transient filter
Internal input fuse T6.3A H.B.C. not user replaceable
Note: In case of a protection event, audible noise may occur.

Type tests and factory tests:
Conducted by the manufacturer. Do not repeat test in field!
Rules for field test:
Use appropriate test equipment which applies the voltage
with a slow ramp! Connect L and N together as well as all
output poles.
The output voltage is floating and has no ohmic connection to ground.
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 any more when unnoticed earth faults occur.
