DANGER - ELECTRICAL SYSTEM HAZARDS

Before connecting this generator to any building’s electrical system, a licensed electrician must install an isolation (transfer) switch. Serious damage to the building’s electrical system may occur without this transfer switch.

CAUTION - BACKUP GENERATOR USE

When connecting the generator to a isolation (transfer) switch, ALWAYS have power applied to the generator's internal battery charger. This will ensure that the engine will not fail due to a dead battery.

When the generator is set in the

AUTO mode, the generator will

NOTE automically start in the event of comercial power falling below a prescribed level by means of a contact closure that is generated automatically by a transfer switch.
