Instructions

Intended use
The radio-controlled switch can be used to remotely switch a con-
nected consumer on and off using a suitable radio transmitter of the
RS2W system.
The radio-controlled switch may only be used on mains voltage
(230 V/AC, 50 Hz). The maximum load for the connected devices is
max. 300 W/1.3 A (resistive load) or max. 30 W/0.13 A (inductive load).
The special design does not require a neutral conductor, which makes
installation in existing electric installations very easy.
It is intended for indoor use only. Do not use it outdoors. Contact with
moisture, e.g. in bathrooms, must be avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or mo-
dify this product. If you use the product for purposes other than those
described above, the product may be damaged. In addition, improper
use can cause hazards such as short circuiting, re, electric shock
etc. Read the instructions carefully and keep them. Make this product
available to third parties only together with its operating instructions.
This product complies with the statutory national and European requi-
rements. All company names and product names are trademarks of
their respective owners. All rights reserved.
Safety instructions
Read the operating instructions carefully and espe-
cially observe the safety information. If you do not fol-
low the safety instructions and information on proper
handling in this manual, we assume no liability for any
resulting personal injury or damage to property. Such
cases will invalidate the warranty/guarantee.
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This may
become dangerous playing material for children.
• Protect the product from extreme temperatures, direct sunlight,
strong jolts, high humidity, moisture, ammable gases, vapours and
solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of
operation and protect it from any accidental use. Safe operation can
no longer be guaranteed if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions
or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even
from a low height can damage the product.
• Also observe the safety and operating instructions of any other de-
vices which are connected to the product.
• This product may only be installed by a qualied technician (e.g., an
electrician) who is familiar with the relevant regulations (e.g., VDE,
German electrical wiring 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 qualied technician.
• Only use the product when it is securely installed and steady. Install
the product e.g. in a suitable ush socket, surface socket or another
suitable enclosure so that the required protection against contact
is ensured.
• Keep the product away from strong magnetic elds occuring near
machines, electric motors or loudspeakers.
• Do not use this product in hospitals or medical institutions. Although
transmitters of the RS2W system only emit relatively weak radio si-
gnals, these may lead to the malfunctioning of life-support systems.
The same may also apply to other zones.
• Never touch or operate the product with damp or wet hands. There
is a risk of a life-threatening electric shock!
• Only carry out the installation when all the mains cables to the radio-
controlled switch are disconnected from the mains voltage. Otherwi-
se, there is a risk of a life-threatening 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.
• Never connect the product to the power supply immediately after it
has been transferred from a cold room into a warm one (e.g., during
transport). Condensation water that forms might destroy the device.
Moreover, there is danger of electric shock!
Allow the device to reach room temperature before switching it on.
Wait until the condensation has evaporated. This might take several
hours. Only after this should it be plugged in to the mains supply
and put into use.
• Never overload the product. Observe the maximally admissible con-
nected load in the chapter “Technical Data”.
• Do not use the product if it is damaged. There is a risk of a life-
threatening electric shock! In this case, dispose of the product in an
environmentally correct manner.
• If it can be assumed that safe operation is no longer possible, the
device must be turned off and precautions must be taken to ensure
that it is not used unintentionally. Do not touch the radio-controlled
switch or any device connected to it.

Operating instructions
RS2W radio-controlled switch
Item no. 1761754
Disconnect the radio-controlled switch from the mains by switching
off at the appropriate circuit breaker or by pulling out the fuse. Fur-
thermore, turn off the earth leakage circuit breaker to disconnect all
the poles of the mains supply.
• Use the product only in a temperate and not in a tropical climate.
• Consult an expert when in doubt about operation, safety or connec-
tion of the device.
• Maintenance, modications and repairs are to be performed exclu-
sively by an expert or at a qualied shop.
• If you have questions which remain unanswered by these operating
instructions, contact our technical support service or other technical
personnel.
Preparations for installation
Please consult the section “Safety instructions”!
• To use the radio-controlled switch, install it in a suitable ush or
surface socket or other suitable enclosure.
• The radio-controlled switch must be disconnected from the pow-
er supply during installation. First, switch off all poles of the mains
supply by switching off at the circuit breaker or removing the fuse
and then also switch off the associated ground-fault circuit breaker.
Secure it against unauthorised reconnection, e.g., with a danger
sign. Afterwards, check the mains connection for absence of volt-
age using a suitable tester.
Installation and connection
Refer to the section “Preparations for Installation”.
In older domestic electric installation systems, there is frequently no
neutral wire in the existing wall sockets. In these cases conventional
wireless switch systems cannot be installed without expensive up-
grading of the wiring and the resulting necessary masonry work.
Thanks to the special 2-wire design of the radio-controlled switch you
do not need the neutral wire - the two existing wires (phase “L” and
switched phase “L´”) are sufcient.
The radio-controlled switch can be used as a complementary compo-
nent providing an additional wireless switching function for a wall switch.
This means you can keep your existing wall switch, and the light, which
has been switched on and off until now at the wall switch, can now also
be operated using a radio transmitter of the RS2W system.
The ush socket has to provide sufcient space to install the ra-
dio-controlled switch behind the existing wall switch.
Therefore, ensure a suitable protection against contact
with connecting, installing and using the radio-controlled
switch. Otherwise, there is a risk of a life-threatening elec-
tric shock!
• Remove the cover of your used wall switch and remove it from the
ush socket.
