The WCU330 is fitted to the wall by fixing it into a standard UK 47mm depth single-gang
back-box (pattress). All knock-outs in the back-box should be removed to provide
maximum ventilation.
Where it is desired to fit a mains lighting switch, etc. next to a keypad, a barrier-box or two
single back-boxes must be used. Bear in mind it is not preferable to fit the keypad next to a
light-switch, particularly if the faceplate styles will differ. Only a qualified electrician should
attempt such installations.
Avoid fitting the WCU330 where there is line of sight to another WCU330 or Opus 500
system main-zone keypads. In such situations, both keypads may pick up the same
commands from a remote control and it will be difficult to control each zone independently.
Avoid fitting the WCU330 where there is line of sight to the source equipment for the
system. In such situations, the source equipment may directly pick up the same IR
commands as are picked up by the keypad and sent to the source equipment. This can
interfere with the remote operation of the source equipment.
Do not fit the keypad in areas directly lit by strong sunlight or where it will be strongly lit by
fluorescent tubes. These can be sources of infra-red energy which may interfere with the
remote control operation of the system. Some plasma televisions can radiate a great deal
of infra-red energy and care should be taken if fitting a WCU330 near a plasma screen
television. Avoid placing the WCU330 near to dimmer switches or other items which
generate a substantial amount of electrical noise.
