Upgrading a dimmer switch
To start, make sure you are familiar with the safety warnings in this leaflet, the instructions supplied with the product and the mains supply is turned off.
2.1.
At the consumer unit, find the trip switch which protects the circuit and turn it all the way off. The indicator window should stay green.
4.3.
Test power is not supplied to the socket by using a plug in socket tester or multimeter. Unscrew the retaining screws on the socket so that it is released from the mounting box.
Gently ease the socket from the mounting box to show the wiring.

5.
Unscrew each terminal to release the wires. You should now be able to remove the switch and place it to once side.
7.
6.
Line up the new switch and take note of where each terminal is located.
8.
Place the brown wire (live) into the COM terminal, the switched live wire (blue/brown stripe) into the L1 terminal and the green/yellow wire (earth) into the separate earth terminal on the face plate.
9.
Gently press the socket back into place over the mounting box. Take care not to trap any wires between the wall and the socket.
Make sure that the wires are fully inserted into the terminal and that no bare copper wire is visible. Tighten the screws securely onto the copper wire, not the outer sheeting.
10.
Insert and tighten the retaining screws provided. Use a spirit level to make sure that the socket is level. Restore the power at the consumer unit and test.
