GENERATOR START-UP PROCEDURE (AUTO MODE)
STARTING (AUTO MODE)
DANGER
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
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.
NOTICE
When the generator is set in the AUTO mode, the
generator will automatically start in the event of
commercial power falling below a prescribed level
by means of a contact closure that is generated
automatically by a transfer switch.
WARNING
When running the generator in the AUTO mode,
remember the generator can start up at any time without
warning. NEVER attempt to perform any maintenance
when the generator is in the auto mode.
CAUTION
The engine speed switch must be set to the “High”
position when running in the auto-start mode. Failing
to set the switch in the proper position can result in
damage to your generator when it turns on.
NOTICE
When the MPEC control switch is placed in the AUTO
position, the engine glow plugs will be warmed and the
engine will start automatically.
When starting generator in AUTO mode use the “Manual
Start-up” procedure except where noted (see below).
1. Perform steps 1 through 5 in the Before Starting section
