GENERATOR CAM LOCK CONNECTIONS (OPTIONAL)
The generator may be equipped with cam lock connections located behind the lug door next to the customer
convenience outlets. These receptacles 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.
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
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 cam lock receptacles.
DANGER
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.
Connections should be made by plugging power cables equipped with series 16 taper nose 400A, 600V cam lock
plugs into the cam lock receptacles.
Secure the connection by rotating the plug a 1/4 turn to the right. The cam lock
connection door is equipped with safety interlock switches that will trip the main circuit breaker and disable the voltage
regulator, dropping the operator output to residual voltage, if the door is opened while the unit is operating.
WARNING
Never attempt to disable or modify the lug door safety switches. Equipment damage,
personal injury or death may result.
A ground connection is located on the far right of the cam lock panel. The unit
MUST
be 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.
