INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON
AND IN ACCORDANCE WITH THE CURRENT EDITION OF THE IEE WIRING REGULATIONS.
WARNING : ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION
FITTING THE BACKPLATE
Once the Backplate has been removed from
the packaging please ensure the programmer
is re-sealed to prevent damage from dust,
debris etc.
The Backplate should be fitted with the wiring
terminals located at the top and in a position
which allows the relevant clearances around
the programmer. (See diagram)
DIRECT WALL MOUNTING
Offer the plate to the wall in the position where the programmer is to be mounted, remembering that
the Backplate fits to the right hand end of the programmer.
Mark the fixing positions through the slots in the Backplate (Fixing centres 60.3mm), drill and plug the
wall, then secure the plate in position. The slots in the Backplate will compensate for any
misalignment of the fixings.
WIRING BOX MOUNTING
The Backplate may be fitted directly on to a single gang steel flush wiring box complying with BS4662,
using two M3.5 screws.
ChannelPlus programmers are suitable for mounting on a flat surface only, they must not be
positioned on a surface mounted wall box or on unearthed metal surfaces.
ELECTRICAL CONNECTIONS
All necessary electrical connections should now be made. Flush wiring can enter from the
rear through the aperture in the Backplate. Surface wiring can only enter from beneath the
programmer and must be securely clamped.
The mains supply terminals are intended to be connected to the supply by means of fixed wiring.
The recommended cable sizes are 1.0mm
