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.
NOTE
Starting (Auto Mode)
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.
DANGER - ELECTRICAL SYSTEM HAZARDS
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.
CAUTION - BACKUP GENERATOR USE
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.
