System Setup
You must perform the following before operating the system:
• If generator is installed in an area regularly subjected
to temperatures below 40°F (4°C), select a 50 second
warm up time by moving jumper JP2 installed on
transfer switch control board from '20' position to
'50' position.

• Set the DPSW1 and DPSW2 dipswitches on the
transfer switch control board to match the KW rating
of the home standby generator, as described in
Setting Dipswitches.
Setting Dipswitches
Dipswitches are used to adjust control board operation
based on generator capacity. DPSW1 and DPSW2 switches
are set to correspond to total system kW rating. Dipswitch
DPSW1 has units of 1,000 watts; Dipswitch DPSW2 has
units of 10,000 watts.
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.

JP2
The "On" position for the dipswitches is the switch number
ON THE TRANSFER SWITCH CONTROL BOARD, not on the
switch. For example, for a 27,000 watt generator, set DPSW2
dipswitch 20 to "On" position. Set DPSW1 dipswitch 7 to
"On" position. 20,000 plus 7000 equals 27,000 watts. Set
CT1 & CT2
only one switch to "On" position on DPSW1 and DPSW2.
Connectors
System Test
With the generator system switch in AUTO, turn the utility
disconnect circuit breaker feeding the transfer switch to the
OFF position. After a few minutes the generator will start and
the transfer switch will transfer to generator power.
Supervisory
Contacts
To return to utility power, turn the utility disconnect circuit
breaker feeding the transfer switch to the ON position.
Controls
Other than a Manual Override lever, there are no operator
controls because this is an automatic transfer switch. The
manual override is to be used only by licensed professionals.
