GENERATOR CAM LOCK CONNECTIONS OPTION

The generator may be equipped with cam lock connections, located behind the lug door next to the generator output
connection lugs. 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 proper connections for selected voltages.
Only a trained and licensed electrician should perform wiring and connections to
unit. Failure to follow proper installation requirements could result in death, serious
Before any connections are made to the generator, verify the main circuit breaker
and control power switch are "OFF/O" and the negative (-) battery cable is discon-
nected. Potentially lethal voltages may be present at generator cam lock receptacles.
IMPROPER OR INCORRECT CONNECTIONS TO A BUILDING'S ELECTRICAL SYSTEM
CAN CAUSE POTENTIALLY LETHAL VOLTAGES TO BACKFEED INTO UTILITY LINES.
THIS MAY RESULT IN INJURY OR ELECTROCUTION TO UTILITY WORKERS NEARBY.
VERIFY THE GENERATOR IS SUPPLYING POWER TO AN ISOLATED OBJECT OR
BUILDING THAT IS NOT CONNECTED TO ANY UTILITY LINES.
Connections should be made by running power cables equipped with series 16 taper nose 400A/600V cam lock
plugs up through the slot in the bottom of the box and into the cam lock receptacles. Secure the connection by rotating
the plug a half turn to the right. The connection lug door is equipped with safety interlock switches that will trip the
main circuit breaker and disable the voltage regulator if the door is opened while the unit is operating.
Never attempt to disable or modify the lug door safety switches. Equipment damage,
