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 mounting rail mounting bracket.
Output over-voltage
protection
Typ.
30.5Vdc
Max. 32.0Vdc
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
IP 20
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 17 (EMC).
Internal input fuse
Included
Not user replaceable slow-blow high-braking capacity
fuse
Touch current (leakage
current)
