INSTALLATION INSTRUCTIONS
1.To avoid fire, shock, or death, turn off power at the circuit breaker and test that power is off before wiring.
2.Open door and remove the interior protective cover by releasing the spring latch (see figure 1 below).
3.Remove the printed circuit board by releasing the spring latch holding the bottom of the board (see figure 2 below).
4.Select knockouts to be used. Remove the inner 1/2” knockout by inserting a flathead 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.
5.Place the enclosure in the desired mounting location, and mark the three mounting holes (refer to Figure 3 below for dimensions). Install the top screw first 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.
6.Connect conduit hubs to conduit before connecting the hubs to the enclosure. After inserting hubs into enclosure, carefully tighten hub lock nut. Do not overtorque.
7.Replace printed circuit board making sure to engage spring latch at the bottom of PCB.
8.Wire in accordance with national and local electrical and safety codes (see wiring diagrams on page 3).
9.Grounding: Terminate all ground wires to the ground lug inside the case at the bottom of the enclosure.
10.Replace interior protective cover.

PROGRAMMING INSTRUCTIONS
The installer should refer to the supplemental instruction manual included with this unit for information regarding setting the time, symbols, keys and programming.
AC voltage must be present at terminals L1 and L2/N for the relays to operate and the status indicator to change from 1
to 1
.
UL Listed
APPLICATION
The GM40AVE Series Time Controls are universal, electronic time switches designed for general purpose commercial applications. The control operates on anyAC 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.

SPECIFIERS GUIDE
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.
BASIC OPERATION
Wiring and load control can be verified by manually turning the unit ON and OFF using the override (OVR) + key.

GM40AVE SERIES TROUBLESHOOTING GUIDE
WARNING
•Some terminals in the Time Switch may be energized even if the yellow and green LED indicators are OFF.
•Check all terminals and wires with an appropriate voltage checker before touching.
PROBLEM: LOAD (Lights/Pumps/Motors, etc) will NOT turn ON or OFF
1.Verify that all wiring connections are correct. (Refer to wiring diagram on page 3)
2.Check the YELLOW Power LED. If ON, it indicates that power is applied to the GM40AVE. NOTE: The relays in the GM40AVE will not operate if AC power is not present.
3. Check the status indicator on the LCD screen. If it indicates OFF 1 , press the + key one time. This will turn both loads ON 1 .
4.Check for correct voltage at terminals (NO) and/or (NO2).
5.Check the status indicator on the LCD screen. If it indicates ON 1
, press the + key one time.
This will turn both loads OFF 1 .
6.Check for correct voltage at terminals (NO) and/or (NO2).
7.Verify that the programming is correct. Refer to the supplemental programming instruction manual included with this unit.
