When connecting the device, note the designa-
tions "IN" [2] and "OUT" [3] as well as the
arrow direction in the electronic cover.
In accordance with national, statutory regula-
tions and the legislation of the country of use,
the personal protection switch must undergo
regular repeat inspections;
e.g. DIN VDE 0701-0702.

Function
The device is all-pole-switching: In the event
of a fault, the power supply via the L and N
conductor is disconnected, and the signal unit

For increased safety, the protective conductor
contact remains closed regardless until the
fault is acknowledged.
Once the fault has been resolved, the device
can be reactivated with the push of a button.
Routine checking takes place every time the
device is plugged in, with the fault-free condi-
tion of the socket being checked.
The protective earth (PE) conductor leads when

The device cannot be switched on or o if:
A conductor in the mains supply is broken
Error voltage is measured on the protective
conductor
Note
If external voltage appears on the
protective conductor, the protective de-
vice switches the L and N conductors
down, but maintains the connection of
the protective conductor circuit.
The device detects and protects against
the following faults:
L conductor break
N conductor break
PE conductor break
Extraneous voltage on PE conductor
Low voltage or power failure
Overvoltage
DC voltage
Incorrect wiring (L and PE conductors
swapped over)
Residual currents with rated value of 30 mA
