 WARNING

Be certain that the power from the utility is turned off

and all backup sources are locked out before starting this

procedure. Failure to do so could result in serious injury

or death. Remember, automatic start generators will start

upon loss of utility mains power unless locked in the “off”

position.

Consult the generator operator manual section to locate the

ATS CONTROL and ENGINE CONTROL module to make sure

both switches are in the OFF position.

 CAUTION

Consult all local and National electrical codes for proper

wiring methods for all wiring.

Install a 50-amp double pole circuit breaker in the load center

(home distribution panel) as a feeder for the ATS for 50-amp

rated ARL.

Install a 100-amp double pole circuit breaker in the load center

(home distribution panel) as a feeder for the ATS for 100-amp

rated ARL.

Install, route and connect (Minimum 75°C) Black L1, and Red

L2 wire appropriate for 50-amp or 100-amp size (dependent on

ARL) between the double-pole feeder breaker in the load center

and the similarly-colored terminals on Utility Supply terminal

block in the ATS through a larger knockout. Strip wires 1/2 inch.

Use Copper Wire only, 75°C Minimum

Route and connect wire of the same AWG between the neutral

bar in the main panel and the White terminal on Utility Supply

terminal block in the ATS. Route and connect a ground wire

between the ground busses in the two panels.

Torque all line voltage connections to 25 in-lbs.
