•Do not overload this accessory or subject it to conditions outside its rating
•This product is Class I and must be earthed
•This product is IP66 rated
INSTALLATION
Note: the unit should be fixed to a rigid flat surface as unevenness could cause damage to the product or affect
operation
•Provide power to the required point of installation (refer to BS7671 for correct cabling methods)
•Remove the front assembly from the backbox and carefully lift off the gasket. Drill the required number
of fixing holes in the backbox (see Fig. 1)
•Using the backbox as a template, mark the location for, and drill the fixing holes ensuring not to
infringe with any gas/water pipes or electrical cables
Fig. 1
•The backbox has drain hole drilling guides marked (see Fig. 2). Drilling a drain hole is advised if the
unit is installed in a location subject to temperature fluctuations where a build-up of condensation may
occur. It is not advised if the unit will be subject to high-pressure jets, as drilling a drain hole will reduce
the IP rating. A 3-5mm hole should be drilled at the bottom back edge of the enclosure where marked.
If wiring in conduit to the bottom entry, then the drain hole should be drilled at the lowest point of the
conduit run not in the backbox

•Remove one or more of the pre-fitted blank plugs as required by pushing out from the inside and install
a suitable IP rated gland or adaptor (not supplied). For rear entry, cut or drill a 20/25mm hole where
marked and install a suitable IP rated grommet (not supplied). Unused cable entries must have the
blank plugs fitted
•Feed the mains cable into the unit and secure the base plate to the surface. The fixing holes are
slotted to allow some rotational adjustment
•Replace the gasket onto the backbox, then wire as shown in Fig. 3 ensuring that correct polarity is
observed: L - Live (brown), E - Earth (green/yellow), N - Neutral (blue)
Fig. 3
•An earth connection must be made to the earth terminal of the socket. Use green/yellow sleeving on
earth conductors that are not insulated. The earth terminal in the backbox is provided for convenience
and does not need to be connected
•Check all electrical connections are secure with no loose strands of cable
•Ensuring the gasket does not become damaged or pinched, fit the socket assembly onto the backbox,
taking care not to compress, damage or trap any cables, and secure with the screws provided - do not
overtighten
•Fit screw covers
•Switch on and check for correct operation

Press the green RESET button to switch on the supply. The red indicator should appear.
To test that the RCD is operating correctly, press the yellow TEST button. The red indicator should
turn green, this will disconnect the load. To restore power, press the green RESET button. The red
indicator should reappear.
If the RCD should trip due to a fault, the RESET button can be pressed after the fault is rectified.
If the RCD will not reset, remove any connected loads and check for faults, water ingress or
damage.
Following a power cut the RCD will automatically reset itself and does not need manually
resetting. Care should be taken to avoid connected loads powering up without warning.
The TEST button should be pressed at regular intervals to check the RCD is functioning correctly.
We recommend testing every 6 months. If the red indicator does not turn green when the TEST
button is pressed, do not use.
