BG ELECTRICAL NXDIMTRIL/A LED Dimmer Switch
Wiring Instructions
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
- Unscrew the accessory from the wall/mounting box.
- 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.
- Unscrew each terminal to release the wire.
2b. New installation
- Install mounting box (metal or moulded) for either flush or surface mounting, ensuring appropriate size of product.
- 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.
- 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)
- Line up the new accessory to mounting box and take note of where each terminal is located.
- 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
- 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).
- 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 & 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).
Features

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

Installation Notes
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 front plates 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 front plate and back box. Front plates WITHOUT screw fixing holes. These products comprise main unit with integral gasket, and front plate as separate item. Fix unit to back box using two fixing screws supplied. Clip front plate 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..
