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.

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.

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.
