Wiring diagrams

How each range is wired, from its instruction leaflet, then general diagrams.

If you are unsure of which wires in your installation are live or neutral, or have any other doubts, please consult a qualified electrician.

Switch off at the mains first. Where two or more wires share a terminal in the old switch, keep them together in the new one.
All metal faceplates must be earthed.

Wiring by range

Rotary dimmers V-Pro, V-Com, V-Dim, V-Plus, V-LED

1-way: Connect one wire to C and the other to L1 (either way round). L2 is not used.
2-way: Replace only one of the two switches with a dimmer; the other stays an ordinary 2-way switch. The wire(s) from the common terminal of the old switch go into C, the other two into L1 and L2 (either way round). Only use one dimmer per circuit.
Multi-gang: Treat each set of three terminals as a separate dimmer. If terminals were linked between gangs on the old switch, link the same terminals on the dimmer with a short wire.

Check: On most dimmers C is next to L1 and L2; on many switches it is at the opposite end. V-Dim dimmers that turn off by rotating are for 1-way circuits only. The V-LED also has an optional neutral terminal for spare neutral connections.

V-Pro Multiway and V-Pro Smart with companion controllers

1-way: The wire to the lights (switched live) goes to the load terminal and the live to the Live terminal. S is not used.
2-way and 3-way: One dimmer and up to two companion controllers, one at each other switch position. Link the S terminals from the dimmer to each companion controller. The total cable length to the furthest companion controller must not exceed 50m.
Neutral available: Neutral goes to the load terminal of each companion controller; Live is linked from the dimmer.
No neutral: Link the load, S and Live terminals from the dimmer to each companion controller.

Important: Never connect neutral to the main dimmer. Standard or retractive switches cannot be used in the circuit.

V-Pro Multi-Point touch and remote, with supplementary controllers

1-way: The live goes to LIVE and the wire to the lights to LOAD. S-LINK is not used.
Multi-way: One master dimmer and any number of supplementary controllers, linked with three (or two) wires: LOAD to LOAD, S-LINK to S-LINK and, optionally, LIVE to LIVE. The total cable length from the master to the last supplementary controller should be no more than 50m.
Live at a supplementary controller: If the supply live arrives at a supplementary controller, the LIVE link to the master is required.
Multi-gang: Treat each group of terminals as a separate dimmer. If only one live wire is present, link the LIVE terminals with a short wire.

Important: A conventional switch cannot be used with this dimmer.

V-Pro Micro in-line dimmers with retractive switches

MDJ160 (single push): Live to the dimmer's input terminal. The white wire (S-Link) goes to the push-to-make terminal of the retractive switch.
MDJ160K (dual push): Live to the dimmer's input terminal. Use a centre-off retractive switch: the white wire (up) and the grey wire (down) go to its two switched terminals.
With a neutral: The black wire goes to the switched live (to the lights) and the neutral to the common terminal of the switch.
Without a neutral: The black wire and the switched live both go to the common terminal of the switch.
More switches: Wire extra retractive switches in parallel, terminal to terminal with the first.

Important: Never connect neutral to the dimmer.

F-Series 1-10V dimmers for drivers and ballasts with a 0-10V or 1-10V input

1-way: The wires from the old switch go to C and L1 (either way round). L2 is not used.
2-way: One F-Series dimmer per circuit, with an ordinary switch at the other end. The common wire(s) go to C, the other two to L1 and L2 (either way round).
Control: Connect the signal wires from the driver or ballast to + and - on the dimmer, using screened 2-core cable with the screen earthed at one end.

Important: Never connect the control terminals to the mains.

Fan regulators 1-way only

1-way: The regulator replaces the single switch for the fan(s) and any lights on the same circuit. Connect the two wires to C and L1 (either way round).

On/off modules (dummy dimmers) MH0, MPINT

MH0: For 1-way or 2-way switching, wired as a switch.
MPINT: For intermediate switching, between two 2-way switches.

Switches and sockets including Impulse, Lever and European

Rocker and toggle switches: 1-way: live to COM, switched live to L1. 2-way: either of the two common forms. Intermediate: between two 2-way switches. On 2 or more gangs, the live may be linked to each COM with a short sleeved wire.
Retractive and momentary: For 1-way and multi-way circuits: wire extra switches in parallel, every L1 together and every L2 together.
Impulse: 1-way: live to C, lights to L1, L2 not used. 2-way: two forms, type 1 and type 2.
Double pole and fan isolators: Supply live and neutral to the supply terminals, the load to the load terminals. On fan isolators the third pair of terminals is for fans with timers.
Sockets: All sockets must be earthed: earth to the earth terminal, live to L, neutral to N.
Telephone extension: Connect terminals 2, 3, 4 and 5 of the master socket to the same terminals of the secondary socket, matching the cable colours. Master sockets should only be fitted by an authorised engineer.
European: Fix with the screws or the claws supplied.

Transformers, LED strip drivers and LEDFix YT transformers, YT40DC, YAGF

Dimmer: Always on the primary (mains) side of the transformer or driver. With YT40DC drivers, do not exceed 250W per dimmer circuit.
Low voltage lamps: Connect lamps in parallel, never in series, and never join the outputs of two transformers. Use equal output cable lengths for even light. Keep at least 30cm between the transformer and a lamp or another transformer.
LED strip: Connect strips in parallel up to the 40W rating, with the correct polarity (red +, black -). To extend, use a terminal block and at least 2 x 1.0mm² cable, kept as short as possible.
LEDFix (YAGF): Wire it in parallel with any one of the lamp fittings.
