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)

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.
