IDIGITAL — 24-Hour Digital Time Switch
INSTALLATION
Preparing the Time Switch
1. Remove the mechanism from the case by depressing
the catch at the top of the case and pulling out, as
shown in FIG. 1.
2. Set the voltage selector for the desired input voltage.
The time switch is shipped with voltage set for 277
VAC.
To operate at 120, 208 or 240 VAC, move the
selector switch to the desired setting as marked
on the circuit board.
See FIG. 2.
3. The timer is shipped with DST (Daylight Saving Time)
enabled. To disable DST, move the jumper from Spare
to DST. See FIG. 2.
4. Choose and remove the selected knockout(s) from the
enclosure.
Note:
There are five 1/2
"
to 3/4
"
combination knockouts
available. There are two on the bottom of the
enclosure, one on each side, and one on the rear.
If a 3/4
"
knockout is needed, remove the 1/2
"
knockout first, then the 3/4
"
knockout.

Mounting the Time Switch
1. Mount the enclosure in the desired location using the
three mounting holes provided. Position at eye level if
possible, providing space to the left of the enclosure for
the cover to swing open. See FIG. 3.
2. Replace the mechanism in the enclosure.

Connecting the Wires
1. Lift the left side of the plastic insulator off the retaining
post and pivot it up and away to expose the terminal
strip. See FIG. 4.
2. Strip the supply and load wires to 1/2".
Use #14-#12
AWG wires, rated at least 75°C (167°F)-COPPER
conductors ONLY
.
3. Insert the wire ends under the proper terminal plates
and tighten the screws firmly. See FIG. 5.
4. Connect the ground wire to the grounding terminal at
the bottom of the enclosure. See FIG. 4.
5. Replace the plastic insulator on the retaining post.
Note:
If the Time Switch is being powered from a different
circuit than the load, you do not need to install the
jumper wire. If the Time Switch is being powered
from the same circuit as the load, install the jumper
wire.
