Precautions with Motor
Cable
Install the motor cable away from other cable routes. Avoid parallel runs with
other cables.
WA R N IN G ! The brake control terminals carry a dangerous DC voltage
(>600V). No device other than an ABB Drives dynamic braking device may
be connected to the UDC+, BR, and UDC- terminals.
Connecting the Control
Unit to the Inverter

The cable coming out of the Control Unit is to be connected to connector
X604 on the Inverter Module. The connector must be secured with the thumb
screws. The cable provided is 6 feet long, and should not be extended.
The yellow/green grounding wire that is connected to one of the PE terminals
on the left side of the Inverter Module is also to be connected to the Control
Unit Chassis (PE2).
Connecting the Ground
