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 L input is connected to an internal fuse. Refer to Control Board Fuse Specifications for the internal fuse value and part number. The N input is not internally fused. External protection is required if N is not connected to a neutral conductor. A dual pole ganged breaker is recommended to protect the control supply wires. Refer to Electrical Specifications (Common) for more information.

The Control Supply contains an internal filter but you could be required to add an external filter for CE compliance. Install the external filter as close as possible to the drive. Use a Schaffner FN2080 filter, an Aerotech UFM-ST noise filter module, or equivalent device.
