Control 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.

The Control Supply input supplies power to the communications and logic circuitry of the drive . The +24V input is connected to an internal fuse. Refer to Control Board Fuse Specifications for the internal fuse value and part number. For an isolated DC supply, connect 0V to protective ground at the supply. Use twisted pair wiring to minimize radiated noise emissions (refer to Control Supply Connections).

Use a control power supply that is dedicated only to the iXA4/XA4 drives to minimize noise. Do not use this supply to power other system components. Locate the power supply close to the drives.
