Wiring the Main Circuit Terminal
WARNING! Electrical Shock Hazard. Shut off the power supply to the drive before wiring the main circuit terminals. Failure to comply
may result in death or serious injury.
Wire the main circuit terminals after the terminal board has been properly grounded.
Models CIMR-L 2A0018 through 2A0075 and 4A0009 through 4A0039 have a cover placed over the DC bus and
braking circuit terminals prior to shipment to help prevent miswiring. Use wire cutters to cut away covers as needed for
terminals.

WARNING! Fire Hazard. The braking resistor connection terminals are B1 and B2. Do not connect braking resistors to any other
terminals. Improper wiring connections could cause the braking resistor to overheat and cause death or serious injury by fire. Failure to
comply may result in damage to the braking circuit or drive.
