2. Note the cable connections: The illustration shows 1 wire of each color 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 molded) for either flush or surface mounting, ensuring the appropriate size of the 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.

3. Connection (See diagram)

1. Line up the new accessory to the 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)

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.

Care

To maintain the high-quality appearance of decorative finish switches and sockets, BG Electrical recommends 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
