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.
2a. Replacing an existing accessory
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 fl ush or surface
mounting, ensuring appropriate size of product.
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 fi tted to the entry point.
3. Cables should be prepared so a suffi cient 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 fi tted.
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)
4. Complete Installation & Test
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.
This product can only be an one way switching circuit where one switch
controls a light (or circuit) i.e. on of off.
The touch dimmer (master) switch should replace that switch.
For two way switching, where a light (or circuit) is controlled by two switches, the Master touch dimmer must be used with a Slave touch dimmer.
A Master touch dimmer cannot be used in combination with a traditional
light switch or any other dimmer switch.
Please refer to the wiring diagrams for guidance.
If the installation uses a four lug metal mounting box, remove the top and
bottom lugs or bend fully back.

Additional Advice for Decorative Products
Fixing method varies depending on which product range is supplied.
Always ensure wall surface is reasonably flat and smooth, with no bumps
or projections. Metal frontplates WITH screw fixing holes, fix the unit to
the back box using two fixing screws supplied. All Decorative products
MUST have an earth connection between the frontplate and back box.
Frontplates WITHOUT screw fixing holes. These products comprise main
unit with integral gasket, and frontplate as separate item. Fix unit to
back box using two fixing screws supplied. Clip frontplate onto main
assembly, ensuring screwdriver notch is located bottom right hand
corner.
To remove plate, place medium size flat bladed screwdriver in notch and
lever off against gasket.
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 frontplates
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 frontplates lacquer/plated finish, although the function will remain
unaffected.
