GENERATOR CAM LOCK CONNECTIONS OPTION

The unit may be equipped with cam lock connections, located below the receptacles. These receptacles provide
connection points for the 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.
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 Electrical Code (NEC), state and local regulations. Failure to follow
proper installation requirements may result in equipment or property damage, per-
Before any connections are made to the generator, make sure that the main circuit
breaker and the Control Power switch are OFF (O) and that the negative (-) battery
cable is disconnected. Potentially lethal voltages may be present at the generator
IMPROPER OR INCORRECT CONNECTIONS TO A BUILDING'S ELECTRICAL SYSTEM
CAN CAUSE POTENTIALLY LETHAL VOLTAGE TO BACKFEED INTO 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 1/2 turn to the right. The 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.
DO NOT attempt to disable or modify the lug door safety switches. Equipment damage,
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 generator neutral is bonded to ground when it is shipped from the factory.
The bonding plate will need to be removed when the generator is used as a standby power source. INSTALLATION
SHOULD BE IN COMPLIANCE WITH THE NATIONAL ELECTRICAL CODE (NEC),STATE AND LOCAL REGU-
LATIONS.
