Installation
The unit is suitable for connection to a 230V ac 50Hz
electricity supply. It is suggested that 3-core round flexible
cable of 1sq.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.
IMPORTANT
Switch off the electricity at the fuse box by removing the
relevant fuse or switching off the circuit breaker before
proceeding with the installation.
Open the unit by gently prying the “ears” on each side of
the unit. See diagram A. This can be done without a tool,
but if you prefer use a flat blade screwdriver, but be
careful not to damage the clips. They should release easily.
The front cover is hinged at the top, the front cover will
swing open upwards.
Using the unit as a template, drill the holes. Insert the wall
plugs into the holes. See diagram B.
It is recommended that the grommet is pierced with a
screwdriver to ensure a better seal.
Fix the unit to its mounting surface. Do not overtighten
the mounting screws as this could damage the unit. If
using a power screwdriver, use the lowest torque setting.
Remove the cable clamp. See diagram C
Pierce and pass the cables through the grommet.
We recommend you use a screwdriver to pierce the
grommet as this will give a better seal.
