Interfaces
Warning:
Risk of electric shock
If the interface inputs and outputs are energised too high and are not
sufficiently insulated, metallic parts, e.g., the housing, may be energised
in the event of a fault.
Isolate low voltage inputs and outputs over 25 V AC or 60 V DC reli -
ably according to DIN EN 61140, or by double or enhanced insulation
according to DIN EN 60730-1 or DIN 60950-1.
Use only shielded connection cables. Connect the shielding to the
connector.
Caution:
Possible damage to the cooling system
If the connections on the device are not covered, liquids could reach
the live components. Ingress of liquids can lead to malfunctions of the
interfaces and can lead to a short circuit.
The interface connections on the rear of the device must always remain
covered.
In which fault situations a signal is output via the interface can be set
via the display.
