Figure 41. MPEC Control Switch (AUTO)

When the generator is set in the

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.

WARNING - AUTO MODE MAINTENANCE

DCA-20SPX — GENERATOR START-UP PROCEDURE (AUTO MODE)
