Operation and installation instructions
Safety instructions
Electrical equipment may only be installed and assembled by qualied electricians.
Failure to comply with these instructions may result in damage to the device, re, or oth-
er hazards.
Function
The residual-current circuit-breaker is used to protect persons against residual electrical cur-
rents.
The residual-current circuit-breaker is a safety protective device with voltage-independent resid-
ual-current triggering as per VDE 0664.
The residual-current protected outgoing feeders (see Figure 5) are used to connect socket-out-
lets or other loads.
The residual-current protection encompasses all devices and cables connected to the residu-
al-current circuit-breaker.
The electrical wiring upstream of the device is not protected.
Operation
Getting the system ready for operation

Performing a functional test
The functional test must be carried out at regular intervals.
Recommendation: 1 x per month
The operating voltage is connected.
Switch on residual-current circuit-breaker with push-button ((a), Figure 1).
Voltage is present at the downstream socket-outlets and loads.
Press test button T((b), Figure 1).
Figure 2
The residual current circuit-breaker trips and the push-button moves to the “Off” position
(Figure 2). Downstream socket outlets/loads are de-energised. The functional test has been
passed.
or:
The residual current circuit-breaker does not trip and the push-button remains in the “On”
position (Figure 2).Residual-current circuit-breaker is now ready for operation.
Replace the residual-current circuit-breaker and repeat the functional test.
Information for electricians
Installation and electrical connections
DANGER!
Touching live parts can result in an electric shock!
An electric shock can be lethal!
Disconnect the connecting cables before working on the device and cover all
live parts in the area!
ç
The wiring must be adapted to the existing power mains. Check the power mains before any
wiring work.

Press the release buttons ((a), Figure 5) for the corresponding plug-in terminal and pull out
the terminal leads.
Installing the residual-current circuit-breaker
The residual-current circuit-breaker is intended for installation in a standard commercial
flush-mounted device-connection box according to DIN 49073, part 1.
The residual-current circuit-breaker is now ready for installation.
Position the residual-current circuit-breaker in the flush-mounted device-connection box.
Screw the residual-current circuit-breaker to the flush-mounted device.connection box using
the screw holes in the support ring.
Position the frame.
Fit centre plate with intermediate ring (see accessories) and fasten with screws.
The residual-current circuit-breaker is now ready or commissioning.
Commissioning
Before commissioning
- carry out a functional test.
- test the safety measures.
DANGER!
Touching live parts can result in an electric shock!
An electric shock can be lethal!
Do not put the residual-current circuit-breaker into operation if the functional
test is failed or the maximum permissible earthing resistance is exceeded!
