Wiring Instructions

Before commencing work always isolate the power at the consumer unit
/ fuse box.
*Note – If your installation uses a four-lug metal mounting box, remove the
top and bottom lugs or bend fully back.

1. Unscrew the accessory from the wall/mounting box.

2. Note the cable connections:
The illustration shows 1 wire of each colour connected to each terminal.
There should be an additional connection between the mounting box earth
terminal and the accessory earth terminal.

3. Unscrew each terminal to release the wire.

1. Install mounting box (metal or moulded) for either flush or surface
mounting, ensuring appropriate size of product (Mounting box to be
purchased separately).

2. Select the most suitable entry point of the mounting box (knock-out) and
route the cables through. If a metal box is used, a cable grommet should
be fitted to the entry point.

3. Cables should be prepared so a sufficient conductor length reaches the
terminals. Strip the ends of the individual conductors leaving an adequate
length bare to enter terminals.

1. Line up the new accessory to mounting box and take note of where each
terminal is located.

2. Connect each wire to the matching terminal.
An earth connection should always be made between the mounting box
earth terminal and the accessory earth terminal, where fitted.
All bare earth wires must be sheathed with green/yellow sleeving.
When connecting the new accessory ensure that only the bare end of the
wire enters the terminal and no bare wires are visible.

3. Tighten terminal screws securely. (Do not over tighten)

1. Carefully position the accessory into the mounting box, ensuring that no
wires are trapped between the plate and the wall and secure with screws
(do not over tighten) then insert screw covers (optional).

2. Once the installation has been completed correctly, replace the fuse/
reset MCB (trip), switch the power back on at the consumer unit and test.

The flex outlet arrangement comprises a fixed portion
integral to the main unit and a movable clamp portion,
held in place by a screwed fixing.
The appliance cable exits through the aperture on the
front/bottom face of the unit.

1. Prepare the flexible cable from the appliance as shown in the diagram.*
*NOTE - The cord clamps are reversible and should be orientated to suit
cable size to give proper clamping.

2. Loosen the cord grip screw fixing, remove blanking plug and pass cable
through the aperture.

3. Connect wires as shown in diagram.

4. Adjust protrusion of cable in clamp so that wires are not taut and then
fully tighten clamp to securely grip cable outer sheath.

DO NOT clamp on individual wires.

IMPORTANT

The cable MUST be clamped tight on outer sheath to ensure the cable con­nections are not damaged or disconnected through subsequent movement
of cable or appliance.

Care

To maintain the high quality appearance of decorative finish switches and
sockets, BG Electrical recommend the use of a soft cloth periodically to
clean the front face. When installing a decorative product please ensure
that the wall is decorated, finished and free of moisture prior to installa­tion.
BG Electrical recommends avoiding using, but not restricted to, these
substances from becoming in contact with the decorative metal front-plates
when cleaning or decorating:

• Adhesive tape, including low tack masking tape

• Solvents

• White spirit

• Multi surface cleaners

• Industrial multipurpose cleaning wipes

• Wet wipes
Using items like those listed above may cause a degrading effect to
the front-plates lacquer/plated finish, although the function will remain
unaffected.
