SELECT
Once the Backplate
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 a
total clearance of at least 50mm
around the programmer.
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 left 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. CentaurPlus 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.
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 2 or 1.5mm 2 .
