When the GM40AV is used to control a single phase 120 VAC
load, connect a jumper wire (J1) between L1 and COM.
When the GM40AV 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.
When the GM40AV 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.
When the GM40AV 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.

This Time Switch is designed to control one or two single phase loads. Do Not use to directly control
three phase loads. Consult a qualied electrician if you are required to control three phase equipment.

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
o
C (194
o
F) rating.
Over current protection shall have an interrupting •
rating sufcient 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.•
