GENERAL INSTRUCTIONS
SAFETY
• This product must be installed in accordance with the latest edition of the IEE Wiring
Regulations (BS7671) and current Building Regulations. If in any doubt, consult a
qualified electrician
• Please isolate mains prior to installation or maintenance
• Check the total load on the circuit (including when this product is fitted) does not exceed
the rating of the circuit cable, fuse or circuit breaker
• Please note the IP (Ingress Protection) rating of this product when deciding the location
for installation
• 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 (outdoor socket outlet) / IP20 rated (RCD plug)

INSTALLATION
• Choose a suitable position for the outdoor socket outlet. It should be fixed to a rigid flat
surface as unevenness could cause damage to the product or affect operation
• Choose a suitable location close to the socket outlet to bring the supply cable through
the wall to inside the building
• Drill a suitable hole through the wall, ensuring not to infringe with any gas/water pipes
or electrical cables. The hole should slope very slightly down towards the outside in order
to prevent water ingress through the wall
• Remove the socket outlet 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
build-up of condensation may occur. It is not advised if the unit will be subject to spray
or jets, as drilling a drain hole will reduce the IP rating. A 3-5mm hole can be drilled at
the bottom back edge of the enclosure where marked
• Remove one of the pre-fitted blank plugs as required by pushing out from the inside
Remove the lock ring from the IP66 gland, insert the gland through the hole, screw the
lock ring onto the gland and tighten. Any unused cable entries must have the blank plugs
fitted
• Feed the mains cable into the unit and tighten the gland onto the cable
• Secure the baseplate 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 the correct
polarity is observed: L - Live (brown), E - Earth (green/yellow), N - Neutral (blue)
Fig. 2

• An earth connection must be made to the earth terminal of the socket.
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
• Pass the cable through the wall and cut to suitable length if required
• Remove the terminal cover from the RCD plug and wire as shown in Fig. 4 ensuring the
correct polarity is observed: L - Live (brown), E - Earth (green/yellow), N - Neutral (blue)

•Secure the cable with the cord grip provided
•Close the terminal cover and fasten with the screws provided
•Plug the RCD plug into a socket outlet, switch on and check for correct operation. See below for
operation of the RCD
For security, and to prevent unwanted tampering with the socket outlet, a lug feature with a 6mm hole is
provided to accept a padlock or similar locking security device (not included).
Note: The power indicator is lit when there is power to the unit and the switch is on, irrespective of whether a
load is plugged in or not.
RCD TEST PROCEDURE
When the RCD is first plugged in, press the green RESET button to switch on the supply to the socket. The red
indicator should appear.
To test that the RCD is operating correctly, press the blue TEST button. The red indicator should turn black and
power to the socket should be disconnected.
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 from the socket outlet and check for 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 that the RCD is functioning correctly. We
recommend testing every 3 months. If the red indicator does not turn black when the TEST button is pressed,
do not use.
The RCD plug is fitted with a 13A fuse to BS1362. To replace the fuse, gently prise open the fuse carrier with a
small flat-bladed screwdriver.
WARNING
To ensure continued safe and proper weatherproof operation, the unit must not be left with the cover raised
open or the catch left unlocked.
This product must be disconnected from the circuit if subjected to any high voltage or insulation resistance
testing. Irreparable damage will occur if this instruction is not followed.
GENERAL
This product should be recycled in the correct manner when it reaches the end of its life. Check local authorities
for where facilities exist.
