Owner's Manual

Installation & Operating Instructions
GM40AV Series General Purpose Electromechanical Commercial Time Switches
• Read instructions completely before installation and retain for future reference.
• To avoid fire, shock, or death, turn off power at circuit breaker and test that power is off before wiring.
• Observe all national and local electrical and safety codes.
• Disconnect power when servicing or changing loads.
• For outdoor locations, rain-tight or wet location conduit hubs that comply with the requirements of UL
514B Conduit, Tubing, and Cable Fittings, must be used.
• This Time Switch is designed to control one or two single phase loads. Do Not use to directly control
three phase loads. Consult a qualified electrician if you are required to control three phase equipment.
• 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 meter before touching.
• The circuit conductors shall have an ampacity not less than the maximum total load to be controlled.
• For all connections, use only copper min. 8 AWG wire for 40 A loads or 10 AWG for 30 A loads, min. 90
o
C
(194
o
F) rating.
• Over current protection shall have an interrupting rating sufficient 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).
• This enclosure does not provide grounding between conduit connectors. When metallic conduit is
used, you must also install grounding type bushings and jumper wires in accordance with the (NEC)
National Electrical Code Requirements.
• Replace insulating panel after wiring or service.
WARNING
1. Open door and remove the interior protective cover by releasing the spring latch (See Figure 1).
2. Remove the printed circuit board by releasing the spring latch holding the bottom of the board
(see Figure 1).
3. Select knockouts to be used. Remove the inner 1/2” knockout by inserting a 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.
4. Place the enclosure in the desired mounting location, and mark the three mounting holes (refer
to Figure 2 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 enclo-
sure through the mounting holes while passing each screw through one of the supplied spacers
and in to the wall.
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. Replace printed circuit board making sure to engage spring latch at the bottom of PCB.
7. Wire in accordance with national and local electrical and safety codes (see wiring diagrams).
8. Grounding: Terminate all ground wires to the ground lug inside the case at the bottom of the
enclosure.
9. Replace interior protective cover.
10. Close the enclosure door.

SETTING THE CLOCK TIME
Rotate the program dial gradually clockwise until the time of day on the outer dial is nearly
aligned with the triangle marker at the 2 o’clock position. Then set time to the minute by rotating
minute hand clockwise until the time of day (and AM or PM) on the outer dial is aligned with the
triangle marker on the inner dial.
PROGRAMMING INSTRUCTIONS
TRIPPERS IN
Green Status LED: OFF
(Normally-open contacts open)
TRIPPERS OUT
Green Status LED: ON
(Normally-open contacts closed)
MANUAL OVERRIDE OPERATION
With the manual switch in the middle position, the GM40AV is
in automatic mode and will switch at the programmed times.
In the upper position “I”, the load is continuously ON.
In the lower position, “O”, the load is continuously OFF.
• Jumper wires are not included.
• Alterations or modifications to the device will void the warranty.
• Do not rotate the dial or minute hand counter-clockwise. Doing so will damage the timer.
