Installing the Schedule Timer
<Note 1> Avoid twisting the inter-unit control wiring
or the input/output wiring together with
power or other wiring, and avoid running
them in the same metal conduit. Doing so
can cause malfunction.
<Note 2> Install the schedule timer at a location
away from any sources of electrical noise.
<Note 3> Install a noise filter or take other appropri-
ate action if electrical noise affects the
power supply circuit of the unit.
(1) Open the panel on the schedule timer unit. Insert
a standard (flat-head) screwdriver or similar tool
into the notches on the bottom of the schedule
timer unit to open and remove the back case.
(2) Use the 2 supplied M4 small screws and install the
schedule timer back case onto the switch box.
Before installing, use a screwdriver or similar tool
to press on and open the screw holes that corre-
spond to the JIS box that is used.
When fastening the case, use spacers and do not
tighten the screws too much. If the schedule timer
does not fit tightly against the wall, cut the spacers
as required to make adjustments.
(3) Connect the supplied power wire (2-core) and
inter-unit control wire (3-core) to the schedule
timer unit. (Refer to “Wiring the Schedule Timer.”)
(4) Align the schedule timer unit with the tabs on the
back case and press to install it.
