Wiring Instructions

1. Power Off
   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.

2b. New installation

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.

Connection (See diagram)

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

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.

Switch types
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, 5 & 6) repeat.
Two Way Switching
Two way switching is used where a light is controlled by two switches.
For multiple gang switches (2, 3, 5 & 6) repeat.
Bell Push
The bell push is a one way switch with a retractive rocker switch.
Before installing, ensure the bell unit is suitable for supply voltage.
Intermediate Switching
Intermediate switching is used in installations that require three or more switches to control a light, and should be used together with two 2-way switches.

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 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.
