GENERATOR OUTPUT CONNECTION LUGS
The generator is equipped with connection lugs behind the lug door next to the customer convenience outlets. The
lugs provide connection points for attachment of external loads to the generator. A large decal on the inside of the
connection lug door details the proper connections for selected voltages.
Connections to the lugs should be made by running the power cables up through the slots in the bottom of the
rubber shield at the base of the box and not directly to the lugs. Use a hex-wrench to tighten the cable connec-
tions. The connection lug door is equipped with safety interlock switches that will trip the main circuit breaker and
disable the voltage regulator, dropping the generator output to residual voltage, if the door is opened while the unit
is operating.
A ground connection is located next to the connection lugs. The unit MUST HAVE this ground lug connected to a
good earthen ground for proper operating safety. The ground connection SHOULD BE IN COMPLIANCE WITH
THE NATIONAL ELECTRIC CODE (NEC) AS WELL AS ANY STATE OR LOCAL GUIDELINES OR CODES.
Before any connections are made to the generator, make sure that the main circuit breaker and
the engine start switch are in the OFF “O” position and that the negative (-) battery cable is
disconnected. Potentially lethal voltages may be present at the generator connection lugs.
WARNING
It is HIGHLY RECOMMENDED that only a trained and licensed electrician perform any
wiring and related connections to the generator. Installation should be in compliance with the
NATIONAL ELECTRIC CODE (NEC) as well as any local or state guidelines as required by law.
Failure to follow proper installation requirements may result in equipment or property damage,
personal injury or death.
WARNING
IMPROPER OR INCORRECT CONNECTIONS TO A BUILDINGS ELECTRICAL SYSTEM CAN CAUSE
POTENTIALLY LETHAL VOLTAGE TO BACKFEED ONTO UTILITY LINES. THIS MAY RESULT IN
INJURY OR ELECTROCUTION TO UTILITY WORKERS NEARBY. MAKE SURE THE GENERATOR IS
SUPPLYING POWER TO AN ISOLATED OBJECT OR BUILDING THAT IS NOT CONNECTED TO ANY
UTILITY LINES.
DANGER
NEVER attempt to disable or modify the lug door safety switches!
