• In main breaker panel, turn selected load circuit
breakers to the ON position.
Setting Dipswitches
Dipswitches are used to adjust control board operation
based on generator capacity and fuel source. SW2 ("ONE")
and SW3 ("TEN") switches are set to correspond to total
system kW rating. Dipswitch SW2 has units of 1,000 watts;
Dipswitch SW3 has units of 10,000 watts.
IMPORTANT: Set only one switch to "On" position on
SW2 and SW3.
NOTICE: Use extreme caution when setting dipswitches or
damage to control board will result.
• Use a pencil or small piece of plastic to set the dipswitch.
• NEVER use a screwdriver or any type of metal object to
set dipswitches.

The "On" position for the dipswitches is the switch number
ON THE CONTROL BOARD, not on the switch. For example,
on a 27,000 watt generator, set SW3 dipswitch "20" to "On"
position. Set SW2 dipswitch "7" to "On" position. 20,000
plus 7000 equals 27,000 watts.
IMPORTANT: After installation of the system is complete,
turn on utility power to the home standby generator and
transfer switch. Wait one minute before turning generator
system switch to AUTO.

System Test

With the generator system switch in AUTO, turn the service
disconnect feeding the transfer switch contactor to the OFF
position. After a few minutes the generator will start and the
transfer switch will transfer to generator power.
Press the test button on the control module (labeled "SW1
TEST") in the enclosure. As the button is pressed, a relay will
energize. Each time the button is pressed, the previous relay
that was energized will de-energize and the next relay will
energize. This sequence continues until all relays have been
tested. If the test button has not been pressed for a period of
30 seconds, the test sequence will halt and the system will
revert to automatic control.
To return to utility power, turn the service disconnect feeding
the transfer switch to the ON position.
