Fing the Back Plate

1. Posion the wall-plate (terminals along top edge) with 60mm

(min) clearance to its right, 25mm (min) above, 90mm (min) below.

Ensure that the supporng surface will fully cover the back of the

programmer.

2. Oﬀer the back plate to the wall in the posion where the

programmer is to be mounted, remembering that the back plate

ﬁts to the le side of the programmer. Mark the ﬁxing posions

through the slots in the back plate, drill and plug wall, then secure

back plate in posion.

3. All necessary electrical connecons should now be made. Ensure

that the wiring to the wall-plate terminals leads directly away from

the terminals and is completely enclosed within the wall-plate

aperture. Wire ends must be stripped and screwed to the terminals

so that minimal bare wire is showing.
