Wiring accessories
Q
The live supply for retractive switches must come from the live (L) connection of the dimmer.
Q
The dimmer must be connected at the live supply end of multiway installations.
Lamps
Q
Do NOT use with Compact Fluorescent Lamps (CFL) even if marked “dimmable”, Fluorescent lamps and Light Emitting Diode (LED) lamps
of any description or motor loads.
Dimmable low voltage transformers
Q
These Electronic dimmer switches, except the 1kW, use leading edge (phase delay) dimming technology and must therefore be used with
compatible good quality dimmable electronic or wire-wound (magnetic) transformers. Trailing edge (phase cut) dimmable transformers
must not be used.
Q
The 1kW dimmer switch uses trailing edge (phase cut) dimming technology and must therefore be used with compatible good quality
dimmable electronic transformers. Do not use the 1kW dimmer with magnetic transformers.
Rotary and 2 way (push) dimmers
Circuits
Q
Only use two-way (push) dimmers in two-way switching circuits. Only use one two-way dimmer in a two-way switching circuit.
Lamps
Q
These dimmer switches are suitable for dimming incandescent lamps and dimmable CFL lamps only and are NOT to be used with
Fluorescent lamps, Light Emitting Diode (LED) lamps of any description or motor loads. Use of non-dimmable CFL lamps may permanently
damage the dimmer or the lamp and will invalidate any guarantee or warranty supplied with the dimmer switch.
Q
It is recommended that a maximum number of 5 dimming CFL lamps only should be connected to an individual dimmer switch.
Dimmable low voltage transformers
Q
Only use Low Voltage dimmers with transformers. Do not use mains voltage dimmers.
Q
The Low Voltage dimmer switches use leading edge (phase delay) dimming technology and must therefore be used with compatible good
quality dimmable electronic or wire-wound transformers. Trailing edge (phase cut) dimmable transformers must not be used.
Co-Axial and Satellite sockets
Non isolated
Non-isolated products are intended for direct connection to a single or two separate TV/FM aerial downleads. These units are not designed
for use in multi outlet systems.
Single TV/FM outlet for connection to a single TV or FM coaxial aerial lead.
Twin outlet for connection to each of two separate TV/FM, coaxial aerial leads.
Diplex and Triplex
Performance
Diplex
TV/FM diplex units for connection to a single coaxial aerial lead with combined TV and FM signals.
The connector standard IEC 169-2 plug for TV and IEC 169-2 socket for Radio.
Triplex
TV/FM/SAT triplex unit for connection to a single coaxial aerial lead with combined TV, FM and satellite signals.
TV: 470-860MHZ
Radio: (FM) 87.5 – 108 MHz and (DAB) 217.5 – 230 MHz.
Satellite: DC – 200kHz and 950-2300MHz.
The connector standard is ‘f’ for satellite, IEC 169-2 plug for TV and IEC 169-2 socket for Radio.
