INSTALLATION
Note: For outdoor locations, raintight, or wet location conduit
hubs that comply with requirements of UL 514B (standard for
fittings for conduit and outlet boxes) are to be used.
1. Open door and then remove interior protective cover by
releasing spring clip on bottom.
2. Remove timer mechanism by releasing spring clip on bot-
tom.
3. Select knockouts to be used. Remove inner 1/2” knockout
by inserting a screwdriver in the slot and carefully punch
knockout loose. Remove slug. If 3/4” knockout is required,
remove the outer ring with pliers after removing the 1/2”
knockout. Smooth edges with knife if necessary.
4. Place enclosure in desired mounting location and mark the
three mounting holes (refer to diagram below). Start by
placing set screw on top and attaching enclosure over
keyhole: then screw in remaining two screws on bottom.
5. Connect conduit hubs to conduit before connecting the
hubs to the enclosure. After inserting hubs into enclosure,
carefully tighten hub lock nut. Do not over-torque.
6.
Verify voltage selection. 120VAC – position switch UP;
208/240VAC – position switch DOWN (refer to Fig. B)
.
7. Wire in accordance with National and Local Codes.
8. Grounding: Terminate all ground wires to ground lug on
bottom of enclosure.
9. Replace interior pro-
tective cover.
