power is off before wiring.
Open door and remove the interior protective cover by releasing the spring 2.
latch (see gure 1 below).
Remove the printed circuit board by releasing the spring latch holding the bot-3.
tom of the board (see gure 2 below).
Select knockouts to be used. Remove the inner 1/2” knockout by inserting a 4.
athead screwdriver in the slot and carefully punch the knockout loose. Remove slug. If 3/4” knockout is required, remove the outer ring with pliers after
removing the 1/2” knockout. Smooth edge with knife, if necessary.
Place the enclosure in the desired mounting location, and mark the three 5.
mounting holes (refer to Figure 3 below for dimensions). Install the top screw
rst with one of the supplied spacers, and then hang the enclosure by the keyhole. Drive the remaining two screws at the bottom of the enclosure through
the mounting holes while passing each screw through one of the supplied
spacers and in to the wall.
Connect conduit hubs to conduit before connecting the hubs to the enclosure. 6.
After inserting hubs into enclosure, carefully tighten hub lock nut. Do not overtorque.
Replace printed circuit board making sure to engage spring latch at the bot-7.
tom of PCB.
Wire in accordance with national and local electrical and safety codes (see 8.
wiring diagrams on page 3).
Grounding: Terminate all ground wires to the ground lug inside the case at the 9.
bottom of the enclosure.
Replace interior protective cover. 10.

SPECIFIERS GUIDE
APPLICATION
The GM40AVE Series Time Controls are universal, electronic
time switches designed for general purpose commercial applications. The control operates on any AC voltage from 120VAC
to 277VAC. The mechanism is mounted in an indoor/outdoor
enclosure and has been designed for the control of lighting,
heating, air conditioning, pumps, motors, or general electrical
circuits in residential, commercial, industrial and agricultural
facilities.
Furnish and install an Intermatic GM40AVE Auto-Volt Series with digital programmable timer with battery backup. The Auto-Volt input voltage range shall be 120VAC to 277VAC, 50 / 60 Hz. All units shall
incorporate two isolated sets of SPDT contacts that are each rated at 40A, 2 HP @ 277V. LED indicators shall provide Power and Status feedback. Enclosure shall be UL Type 3R, suitable for indoor or
outdoor installation. Timers with battery backup will automatically keep time and do not require resetting after a power outage.
