material damage. 
Contact an electrician! 
•  *) Specialist knowledge required for the installation:
For the installation, in particular, the following specialist knowledge 
is required:
 - -the  “5  safety  rules”  to  be  followed:  Switch  off  power;  secu
re  against  switching  back  on;  determine  voltage-free  status; 
earthing and short-circuiting; cover or fence off nearby live parts
 - Choose  appropriate  tools,  meters  and,  if  necessary,  personal 
protective equipment
 - Evaluation of the measurement results
 - -Selection of the electrical installation material to ensure the shut
down conditions
 - IP protection types
 - Installation of the electrical installation material
 - Type of mains supply network (TN system, IT system, TT system) 
and  the  connection  conditions  that  follow  from  them  (classical 
earthing, protective earthing, required additional measures, etc.)
•  If you do not have the expertise required for the installation, do not 
connect and install it yourself, rather ask a qualied technician. 
•  Do not use this product in hospitals or medical institutions. Although 
RS2W system transmitters only emit relatively weak radio signals, 
these may lead to the malfunctioning of life-support systems. The 
same may also apply to other areas.
•  In  commercial  institutions,  the  accident  prevention  regulations  of 
the  Employer’s  Liability  Insurance  Association  for  Electrical  Sys-
tems and Operating Facilities are to be observed!
•  The product may be mounted in indoor and outdoor areas (housing 
with protection type IP66). However, it must not be installed in  or 
under water. Water can seep into the product, which will destroy it. 
Furthermore, this could cause a lethal electric shock!
•  The product may only be assembled and operated in a stationary 
condition; the product is not suitable for installation and operation 
in vehicles.

RS2W wireless outdoor switch
Item no. 1762779
•  -Do not mount or use this product in rooms or under adverse envi
ronmental conditions where combustible gases, vapours or dust are 
are or may be present! There is a danger of explosion!
•  Keep the  product away from strong  magnetic elds generated by 
machines, electric motors or loudspeakers.
•  The product may only be operated on mains voltage (see sections 
“Installation  and  connection”  and  “Technical  data”).  Never  try  to 
operate the product at another voltage, as this will result in the de-
struction of the product.
•  Only carry out the installation and connection when all the mains 
cables  to  the  inbuilt  wireless  switch  are  disconnected  from  the 
mains voltage. Otherwise, there is a risk of a life-threatening electric 
shock!
•  During installation, all poles must be disconnected from the mains 
voltage, e.g., via RCD. There must be an appropriately dimensioned 
fuse or circuit breaker between the RCD and the product.
•  Install the product only in an easy-to-reach position.
•  If it can be assumed that safe operation is no longer possible, the 
product must be turned off and precautions must be taken to ensure 
that it is not used unintentionally. Do not touch the inbuilt wireless 
switch or any device connected to it.
Disconnect  the wireless  inbuilt switch  completely  from the  mains 
by switching off at the appropriate circuit breaker or by pulling out 
the fuse and switching of the corresponding earth leakage breaker.
After this, arrange for an expert to check the product.
•  Never overload the product. Observe the maximum connected load 
specied in the chapter “Technical data”.
•  If the product is operated while opened (for  a functional check or 
programming), it must not get damp or wet. There is a risk of a life-
threatening electric shock!
If any liquid has still managed to enter the device, immediately turn 
off the mains supply at all poles (turn off the automatic circuit brea-
ker or remove the fuse, then switch off the residual current operated 
circuit breaker of the associated circuits). Contact a specialist. Do 
not use the product any longer.
•  Do not use  the  product if it is  damaged. There is a risk of a  life-
threatening electric shock! 
•  If it can be assumed that safe operation is no longer possible, the 
product must be turned off and precautions must be taken to ensure 
that it is not used unintentionally. Do not touch the product or any 
device connected to it.
First switch  off the mains voltage to all  poles (switch off the con-
nected circuit breaker or remove  the fuse and then switch off the 
connected RCD).
•  -Consult an expert when in doubt about operation, safety or connec
tion of the device.
•  -Maintenance, modications and repairs are to be performed exclu
sively by an expert or at a qualied shop.
•  If you have questions which remain unanswered by these operating 
instructions, contact our technical support service or other technical 
personnel.

Installation and connection
  Please observe the chapter “Safety instructions”!
  The wireless inbuilt switch can be mounted in a suitable 
place. The housing of the wireless inbuilt switch is protec-
ted according to IP66. Thus, it may be installed in unpro-
tected outdoor areas. Make sure that the housing is never 
in or under water. 
  The  wireless  inbuilt  switch  must  be  disconnected  from 
the mains supply  during installation. Turn  off the mains 
supply, by switching off the appropriate circuit breaker or 
by  pulling  out  the  fuse.  Secure  it  against  unauthorised 
reconnection, e.g., with a danger sign.
  Furthermore, turn off the earth leakage circuit breaker to 
disconnect all the poles from the mains voltage.
  Check  that  the mains  connection  is current  free with  a 
suitable tester.
•  Open the cover of the protective housing by removing the 4 screws 
on the top with a screwdriver. You can then remove the cover.
•  The  complete  external  wireless  switch  can  be  removed  from  the 
housing.
•  Remove the two screws on the cover (5) and remove the cover. The 
screw terminals for the two outputs/switching channels  , the (8+9)
input for power supply   and the strain relief (10) (11) for the connec-
tion cables are situated under the cover.
•  -Depending on the installation location and the position of the con
necting cables, up to 4 ller plugs (6) can be used instead of the 4 
cable connections provided.
