load transfer, or they can be completely disabled. The engine-generator should be exercised under load once a week for
a minimum time period of 20 minutes, or follow the recommendations of the engine-generator set manufacturer. Refer
to page 4–2 for location of DIP switches, battery (provided), and jumper block in the controller.
