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 advice of a qualified electrician.
NOTE: LightwaveRF dimmers do NOT require a mains neutral wire to be
connected; they only require 'live in' and 'switched live out'.
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.
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
correctly aligned and that no wires are
trapped between the dimmer switch and
the back box.
