4. INSTALATION
After choosing a suitable location (see previous section) install the unit as follows:-
The unit is suitable for connection to a 230 V ac 50Hz electricity supply. It is suggested that 3-core round flexible cable
of 1.5 sq. mm gauge is used. An internal switch should be installed to switch the power to the unit ON & OFF. This
allows the sensor to be easily switched off when not required or for maintenance purposes.
This product is designed to be mounted on walls
or under eaves, see diagram E. The sensor can
be rotated through 180 degrees to direct
detection where required, consider your location
carefully before installation.
Unscrew the wiring box fixing screw shown on
diagram F. This screw is captive, do not fully
remove.
Detach the wiring box from the Sensor body.
Using the wall plate as a template, mark the
position of the fitting holes.
Drill the holes. Insert the wall plugs into the holes.
PIERCE & PASS THE CABLE(S) THROUGH
THE GROMMET(S) BEFORE PROCEEDING.
It is recommended that the grommet is pierced
with a screwdriver to ensure a better seal.
Attach the mounting plate to the wall using
screws provided. Do not overtighten the
mounting screws as this could damage the unit.
If using a power screwdriver, use the lowest
torque setting.
This unit features an installation aid. Simply hang
the Sensor onto the wall plate by use of the clip
arrangement on the wall plate. See diagram H.
This allows you to use your hands to hold the
screwdriver, and install the incoming cables with
ease.
Connect the incoming and outgoing cables as
follows.

Ensure that connections are secure.
Ensure the terminal block is attached to its mounting posts in the sensor body.
Un-hook the sensor unit from the wall plate and re-attach to the wall plate box as follows:-
1) Ensure no wires are trapped.
2) Align the sensor centrally over the wiring box and attach the top edge of the sensor to the wall plate. See
diagram I.
3) There will be an audible click indicating that the top clips are located into the wall plate. Slowly rotate the sensor
body downwards and ensure no wires are trapped, the lower edge of the unit will locate into the wall plate. Fully
tighten the fixing screw. See diagram F.
