230 V AC
• The sensor should be connected to the conductive elements such as metal casing of lighting fittings,
handles, door handles, etc. These elements must be electrically insulated.
• It is recommended that the surface to which the sensor is connected is as small as possible (it should
not exceed 25 dm
2
). If the surface increases more than 5 dm
2
the difference in the touch sensitivity can
be observed.
• Switching on / switching off the circuits connected to the output terminals of the WDN-03 switch is
realised by a short touch of the item to which the sensor is connected.
• The sensor’s cable can be extended up to a maximum of 3 m with a minimum cross-section of 1 mm
2
.
Control in the switch on / switch off function: another short touching of the conductive part connected
to the sensor.
CAUTION! The WDN-03 switch connection to a single-phase installation must be installed in ac-
cordance with standards valid in a particular country. Installation, connection and control should
be carried out by a qualified electrician staff, who act in accordance with the service manual and
the device functions.
1. Disconnect power supply by the phase fuse, the circuit-breaker or the switch-disconnector combined
to the proper circuit.
2. Check if there is no voltage on connection cables by means of a special measure equipment.
3. Connect the WDN-03 device to 230 V AC voltage.
4. Connect cables to proper terminal clamps of WDN-03 according to the connection diagram.
5. Mount the switch and the sensor on their final place.
6. Switch on the power supply from the mains and check proper functioning of the device..
IMPORTANT:
If during the use of WDN-02 switch there is a need to change the sensor’s connection place, it
can be done without disconnecting the power supply. However it should be remembered, that in
each case after such an operation it is necessary to wait at least 10 seconds to perform the switch
automatic calibration process.
The WDN-03 device is used to switch on or switch off the light by means of a touch. The switch has a
sensor with 1,5 m long wire, which is connected to conductive components of lighting fittings or other
conductive elements having the function of a switch (metal handles, door knobs, metal railings, etc).
The WDN-03 switch is supplied with 230 V AC. It has one voltage output with a maximum load of 5 A /
250 V AC. Using the WDN-03 switch it is possible to switch on / switch off any traditional (conventional
light bulbs, halogens) and low-voltage (12 V AC halogens, LED diodes) light sources. In order to control
the low-voltage sources, it is necessary to connect an appropriate power supply or transformer system
to the switch output. WDN-03 has small casing dimensions and is designed for surface mounting with
a possibility to be screwed to it. It is recommended to use WDN-03 to control lighting in the kitchen
and bathroom furniture. The device can also be installed on flammable materials, e.g. wood, furniture
boards and plasterboard.
The switch features:
• low power consumption during stand-by mode (W) – the device is used to a continuous operation,
• relay output voltage 230 V AC,
• the relay contact with a maximum load of 5 A / 250 V AC,
• automatic calibration process referring to the change of the sensor’s connection place or the touch
surface,
• a possibility to control any light source,
• small dimensions,
• a possibility to screw to the mounting surface.
