Motor Supply Connector

DANGER: Shock and Fire Hazard!

Electrical wiring must be designed and installed in accordance with local electrical safety regulations to prevent the risk of fire and electrical shock.

Motor power is applied to the B+, B-, and RET terminals of the Motor Supply connector. To improve thermal performance of the amplifier, you should use the lowest motor supply voltage that you need for your application. The B+ and B- inputs are connected to internal fuses. Refer to Control Board Fuse Specifications for the internal fuse values and part numbers. For an isolated DC supply, connect RET to protective ground at the supply.

Refer to System Interconnection for additional information.
