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 2A0004 to 2A0081, 4A0002 to 4A0044, and 5A0003 to 5A0032 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.
