Pigtail
Each cable box has pigtails for non cam-type connections.
There is a cam-type on one end and a barrel lug on the
other. The barrel lug end allows for connection into a power
distribution panel or non cam-type equipment. The pigtail
can be connected to the standard cam-type cable, see
Figure 33, p.

Verify power supply available is compatible with the unit
nameplate. The available supply power must be within 10%
of the rated voltage stamped on the nameplate. Use only
copper conductors to connect the three-phase power
supply to the unit.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as the equipment was not
designed or qualified to accept other types of
conductors.

Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
Once the door is open, it can be closed with the handle in
any one of the three positions outlined above. Match the
circuit breaker position.
For specific electrical schematic and connection
information, refer to the ship-with wiring diagram.
