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 flush 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 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 securel
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.
One Way Switching
One way switching is used in installations that require just one switch to
control a light (or circuit) i.e. on or off.
A two-way switch can be used for one way connection, use COM and L1
terminals. For multiple gang switches (2, 3 & 4 repeat wiring method for
each switch).
Two Way Switching
Two way switching is used where a light is controlled by two switches.
For multiple gang switches (2, 3 & 4 repeat wiring method for each switch).
Overload Protection – This dimmer is fitted with an overload current protection
device, in the event of an overload condition the dimmer will stop working until the
overload is corrected. Please check the total load ratings before installing.
Soft Start – To prolong the life of the connected lighting this dimmer features a
soft start function. Upon switching on, lighting will increase from 0 to 100% in 1.2
seconds.

Authority.
Please read carefully and use in accordance with these safety wiring
instructions. Before commencing any electrical work ensure the supply is
switched off at the mains. Either by switching off the consumer unit or by
removing the appropriate fuse or turning off MCB (trip). Wiring should be in
accordance with the latest edition of the IET regulations (BS 7671).
To prevent fire hazard always use cable of the correct rating & type for the
application.
Warning do not exceed the load rating of this device as stated on the rear
of the product.
Wire Identification – Twin & Earth Cable
Note - As from 1st April 2004 new colour codes for hard wire installations
were introduced.
EARTH = Green/Yellow Sleeving
NEUTRAL = Black (pre Apr 04) / Blue (after Apr 04)

Only one dimmer is allowed in a two-way circuit.
If the installation uses a four lug metal mounting box, remove the top and
bottom lugs or bend fully back.
For white moulded products, if the dimmer knob blocks the screw fixing
holes, remove knobs, fix to wall and then reattach knobs.

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 installa
tion.
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.
