NOTE: Ensure the O-Rings are in-place or installed before connection to the controller. Ensure the O-Rings are
not pinched or nicked during installation.
DANGER
Do not connect either the positive or negative high voltage bus to the chassis, motor
cases, or controller. Catastrophic damage will occur. Provide sufficient insulation on all
power terminals for safety.
3.1.1 Phase Cables (3 Phase AC cables)
The phase cables ( Figure 1.1 cable D) supply three phase AC voltage from the inverter to the motor.
The motor ends of the phase cables are permanently attached to the motor at the factory. The controller
electrical connections are shown in
Figure 3.1 . They are the block of 3 cables on the left side of the diagram.
Before connecting the phase cables, remove the termination cover shown in Figure 3.4 .
