WARNING
To avoid re, shock, or death, turn off power at circuit breaker and test that power is off •
before wiring.
Read instructions completely before installation and retain for future reference.•
Observe all national and local electrical and safety codes.•
Disconnect power when servicing or changing loads.•
Alterations or modications to the device will void the warranty.•
For outdoor locations, rain-tight or wet location conduit hubs that comply with the re-•
quirements of UL 514B Conduit, Tubing, and Cable Fittings, must be used.
INSTALLATION INSTRUCTIONS
To avoid re, shock, or death, turn off power at the circuit breaker and test that 1.
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.

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 .

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.
GM40AVE Digital timer controls
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 veried by manually turning the unit ON and OFF using the override
(OVR) + key.

GM40AVE SERIES TERMINAL DESIGNATIONS
GM40AVE SERIES TYPICAL WIRING DIAGRAMS
120 VAC One Load
When the GM40AVE is used to control a single phase 120
VAC load, connect a jumper wire (J1) between L1 and COM.
120 VAC Two Loads
When the GM40AVE is used to control two single phase 120
VAC loads, connect a jumper wire (J1) between L1 and COM
and connect a second jumper wire (J2) between COM and
COM2.
NOTICE! Make sure that the combined amperage of Load 1
and Load 2 do not exceed the limits of the feed circuit.
NOTICE
The circuit conductors shall have an ampacity not •
less than the maximum total load to be controlled.
For all connections, use min. 8 AWG wire for 40 A •
loads or 10 AWG for 30 A loads, min. 90 oC (194
o
F) rating.
Over current protection shall have an interrupting •
rating sufcient for the application control circuit
voltage and the total load current of the equipment
being controlled.
A fuse or circuit breaker shall be connected in •
series with each ungrounded conductor (and shall
be able to simultaneously open each conductor).
Jumper wires are not included.•
240 VAC One Load
When the GM40AVE is used to control a single phase 240
VAC load, connect a jumper wire (J1) between L1 and COM
and connect a second jumper wire (J2) between L2 and
COM2.
277 VAC Two Loads
When the GM40AVE is used to control two single phase 277
VAC loads, connect a jumper wire (J1) between L1 and COM
and connect a second jumper wire (J2) between COM and
COM2.
NOTICE! Make sure that the combined amperage of Load 1
and Load 2 does not exceed the limits of the feed circuit.

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
Verify that all wiring connections are correct. (Refer to wiring diagram on page 3)1.
Check the YELLOW Power LED. If ON, it indicates that power is applied to the GM40AVE. 2.
NOTE: The relays in the GM40AVE will not operate if AC power is not present.
Check the status indicator on the LCD screen. If it indicates OFF 1 , press the + key one time. 3.
This will turn both loads ON 1 .
Check for correct voltage at terminals (NO) and/or (NO2).4.
Check the status indicator on the LCD screen. If it indicates ON 1 , press the + key one time. 5.
This will turn both loads OFF 1 .
Check for correct voltage at terminals (NO) and/or (NO2).6.
Verify that the programming is correct. Refer to the supplemental programming instruction 7.
manual included with this unit.
