Safety and Protection Features
Isolation resistance
Min. 500MOhm
At delivered condition between input and output,
measured with 500Vdc
Min. 500MOhm
At delivered condition between input and PE,
measured with 500Vdc
Min. 500MOhm
At delivered condition between output and PE,
measured with 500Vdc
Min. 500MOhm
At delivered condition between output
and DC-OK contacts, measured with 500Vdc
PE resistance
Max. 0.1Ohm
Resistance between PE terminal and the housing
in the area of the DIN-rail mounting bracket.
Output over-voltage protection Typ. 30.5Vdc
Max. 32Vdc
In case of an internal defect, a redundant circuit limits the maximum output
voltage. The output shuts down and automatically attempts to restart.
Class of protection
I
According to IEC 61140
A PE (Protective Earth) connection is required
Degree of protection
IP20
According to EN/IEC 60529
Over-temperature protection
Included
Output shut-down with automatic restart.
Temperature sensors are installed on critical
components inside the unit and turn the unit off
in safety critical situations, which can happen e.g.
when ambient temperature is too high, ventilation
is obstructed or the de-rating requirements are
not followed. There is no correlation between
the operating temperature and turn-off
temperature since this is dependent on input
voltage, load and installation methods.
Input transient protection
MOV
(Metal Oxide Varistor)
For protection values, see chapter 18 (EMC).
Internal input fuse
Included
Not user replaceable slow-blow high-braking
capacity fuse

At 132Vac, 60Hz, TN-,TT-mains / IT-mains
Max. 0.39mA / 0.94mA
At 264Vac, 50Hz, TN-,TT-mains / IT-mains
