help guide you through setup and installation.
To install the Dimmer, you will need to remove
and replace the existing lightswitch. This is
usually straightforward, but you must ensure that
there is a suitably deep housing (backbox) and
understand how to safely turn o the electricity
supply. You will also need suitable electrical
screwdrivers.

always consult a qualified electrician.

Installation

• The 2-Way Dimmers use standard 3-core connecting cables; however,
because they are electronic dimmers, they utilise one of the cores as a
signal cable (‘S’) running between the Dimmers (as shown on the diagram).
This is low voltage only and should not be connected to 230V mains;
serious damage will occur.
• Up to six 2-Way Dimmers (six gangs) can be connected to a standard
LightwaveRF Dimmer Switch. Each 2-Way can be connected directly to the
standard Dimmer, or connected to each other in a ‘daisy-chain’. This
provides an alternative to using intermediate switches (maximum cable
length of 100m).
VERY IMPORTANT
• A LightwaveRF 2-Way Dimmer (each gang) needs to be used in conjunc-
tion with a standard LightwaveRF Dimmer to perform 2-Way Switching. The
LightwaveRF 2-Way Dimmer cannot be used in conjunction with a
standard lightswitch. This will cause damage to the Dimmer.
• Never install and run power to a 2-Way Dimmer before first installing and
connecting the corresponding standard LightwaveRF Dimmer. Serious
damage could be caused to the unit.
Installation

1. IMPORTANT: Turn o the mains electrical supply.
2. Ensure that the wall (back) box has a minimum depth of 35mm.
3. Remove and disconnect the existing light switch (if applicable). It may be
useful at this point to mark out or take a photograph of the connections to
the existing switch so that the correct wires can easily be transferred to the
new Dimmer. Some existing wiring configurations can be complex so take
care.
4. Gently remove Dimmer faceplate by inserting a screwdriver into the
bottom slot/s and lifting away from the unit as shown.
Installation

5. Connect the wiring as per the wiring diagram on the following page.
Ensure that the terminals are properly tightened and that no bare wire is
visible. Be aware that existing wiring circuits are not always correctly
coloured, and that there may be other wired connections present in the back
box; if in doubt, always seek the advise of a qualified electrician.
NOTE: The 2-Way Dimmer does NOT require a mains neutral wire to be
connected; it only requires ‘live in’, ‘switched live out’ and a ‘signal’ connection.
7. Screw the Dimmer Switch to the
mounting box and ensure that the
screws are suciently tight to support
the product, but do not over tighten as
this may cause the chassis to bend.
Ensure that the plastic spacer is
correctly aligned and that no wires are
trapped between the Dimmer Switch
and the back of the back box.
6. Any earth wires present must be attached either to the earth terminal
located in the back box or capped with a strip connector. The Dimmers are
double insulated so are not required to be earthed directly.

IMPORTANT: The signal cable input
marked ‘S’ must ONLY be connected
to the wire running to the other
Dimmer NOT live mains; this will
cause irreparable damage.
