Use in accordance with manufacturer’s instructions
The radio-controlled flush-mounted switch, in combination with a suitable radio-controlled re-
mote switch of the RSL system is used to wirelessly switch a connected consumer load on or
off.
The radio-controlled flush-mounted switch is only suitable for operation on the mains voltage
(230 V/AC, 50 Hz). A maximum consumer load of 2000 W (Ohm resistive load) or 300 W (induc-
tive load) can be connected.
Any other use than that described above may damage the product. Moreover, this may give
rise to hazards such as short-circuiting, fire, electric shock, etc. No part of the product may be
modified or converted!
Always observe the safety instructions included in these operating instructions. Please read the
operating instructions carefully and store them.
This product complies with the applicable National and European requirements. All names of

Safety instructions
Read the complete operating manual carefully before using the product, as it
contains important information about the correct installation and operation.
The warranty will be void in the event of damage caused by failure to observe
these safety instructions! We do not assume any liability for any consequen-
tial damage!
Nor do we assume any liability for material and personal damage caused by
improper use or non-compliance with the safety instructions! In such cases,
the warranty will be void!
Caution!
The product may only be installed by a qualified technician (e.g. electrician)
who is familiar with the relevant regulations (e.g. VDE, German electrical wir-
ing regulations)!
Improper work, carried out on the mains voltage, endangers not only your
own life but also the life of others!
If you do not have the expertise required for the installation, do not install it
yourself but ask a qualified technician.
• The unauthorised conversion and/or modification of the product is not allowed for
safety and approval reasons (CE). Never dismantle the product!
• The product is not a toy and must be kept out of the reach of children! There is the
risk of a fatal electric shock!
• Do not use this product in hospitals or medical institutions. Although the transmit-
ters of the RSL system emit only relatively weak radio signals, these may lead to
malfunction of life-supporting systems. The same may be the case in other areas.
• The product may only be operated on the mains voltage (see section “Installa-
tion and Connection” and “Technical Data”). Never try to operate the product at
another voltage as this will cause its destruction.
• The installation may only be carried out, if all poles of the mains supplies of the
wireless flush-mounted switch are disconnected from the mains voltage. Other-
wise, there is a mortal danger by an electric shock!
• An all-pole disconnection from the mains voltage (such as a surge protector) must
be provided as part of the wiring set-up.
• The product must be installed and used in dry, closed interiors only, it must not get
damp or wet! Never touch the product when your hands are wet or damp! There is
a risk of a life-threatening electric shock!
• Only use the product when it is firmly mounted and steady. Insert the product e. g.
into a suitable flush-mounted socket or surface box.
• Do not use this product in rooms or under adverse ambient conditions where com-
bustible gases, vapours or dust are or may be present! There is a risk of explosion!
• The product must not be exposed to extreme temperatures, strong vibrations or
heavy mechanical stress.
• If you have reason to assume that safe operation is no longer possible, disconnect
the product immediately and secure it against accidental operation. Neither touch
the wireless flush-mounted switch nor any connected device.
Disconnect the wireless flush-mounted switch from the mains voltage by switching
off the corresponding circuit breaker or removing the fuse. Furthermore, turn off
the earth leakage circuit breaker in order to disconnect all the poles of the mains
supply.
Let an expert check the product.
• A safe operation can no longer be assumed, if:
- the product shows visible signs of damage,
- the product does not work at all or well (flickering light, leaking smoke or a smell
of burning, audible cracking noises, discolouration to the product or the adjacent
surfaces.)
- the product was stored for a longer period of time in unfavourable conditions
- it was exposed to heavy loads during transport
• Do not leave packing materials unattended. They may become dangerous play-
things for children.
• In commercial institutions, the accident prevention regulations of the employer’s
liability insurance association for electrical systems and operating facilities are to
be observed!
• If you have any questions, which are not answered in this manual, please contact
our technical service or another specialist.
Preparations for installation
Please observe the chapter “Safety instructions”!
• The wireless flush-mounted switch must be mounted and operated in a suitable flush-mount-
ed socket or surface box, or in another housing suitable for this purpose.
• Only use the wireless flush-mounted switch when it is firmly mounted.
• The radio flush-mounted switch must be disconnected from the power supply during instal-
lation. For this purpose, switch off the electrical mains supply by switching off at the corre-
sponding circuit breaker or removing the fuse. Secure it against an unauthorised re-start, e.g.
with a danger sign.
Furthermore, turn off the earth leakage circuit breaker in order to disconnect all poles of the
mains supply from mains voltage.
• Check that the mains supply is current free with a suitable tester.
Installation and connection
Observe the chapter “Preparations for installation”
.
The wireless flush-mounted switch can be used as a complementary component providing
an additional wireless switching function for a wall switch. This means the existing wall switch
is still used. However, the consumer load (e. g. a room lighting) connected to the wall switch
can now be controlled additionally using a wireless flush-mounted switch or a wireless remote
control of the RSL system.
This implies that the flush-mounted socket provides sufficient space to install the wireless flush-
mounted switch behind the existing wall switch.
• Loosen the cover of the wall switch and remove the wall
switch from the flush-mounted socket.
• Connect both cables of the wireless flush-mounted switch with
the two switching contacts of your wall switch (“S1”), see pic-
ture on the right.
• Connect the consumer load to the two middle screw terminals,
see picture on the right.
The connection “N” ist the neutral conductor, the connection
“ “ is the connected output/phase/L.
• The outer two screw terminals are used for the connection to
the mains voltage (“N” = neutral conductor, “L” = phase).
• Insert the wireless flush-mounted switch into the flush-mount-
ed socket.
Pay attention that the push-button on the housing’s rear is
exposed during installation and not accidentally pushed.
• The push-button on the housing’s rear is used to “train” or
tune the switch to the radio transmitter of the RSL switching
system.
Therefore, observe the following chapters before you reinsert and refasten the wall switch in
the flush-mounted socket.
