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.
Output protection Electronically protected against overload, no-load and short-circuits *)
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.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 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 included not user replaceable
Input / output separation *) SELV IEC/EN 60950-1
PELV IEC/EN 60204-1, EN 50178, IEC 62103, IEC 60364-4-41

To fulfil 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. A D
