Connect the wiring as shown below.
Option 1: Fitting a new wall-plate
The ideal location is 1.2m above
floor level, with reasonable
lighting, good access, no
condensation, no extremes of
temperature and a supporting
surface that fully covers the
back of the unit. Position with
70mm clearance to the right,
25mm above and sufficient room
to access the securing screws
underneath. Fix, with terminals
at the top, either direct to a flat
wall using wall plugs and no. 6 x
1" (25mm) woodscrews, or on a
flush mounting single conduit box

type UA1 (BS4662) using M3.5 x
14 bolts.
Option 2: Using an existing
wall-plate
Loosen the securing screws
on the old programmer and
unplug it. Check that there is
70mm clearance to the right of
the wall-plate and 25mm above
it. Check the wiring diagram for
your product model to compare
terminals and, if necessary,
change the wiring of the wall-
plate to suit. now plug the MiTime
unit into the wall-plate and tighten
