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 AC1 and AC2 terminals of the Motor Supply connector.
Peak Current Option -10: The AC1 input is internally connected to a 5 A fuse.
Peak Current Option -20 and -30: The AC1 input is internally connected to a 10 A fuse.
Refer to Control Board Fuse Specifications for the internal fuse part numbers.
The AC2 input is not internally fused. The system designer must provide external circuit breaker(s) in accordance with local electrical safety requirements. D-type breakers are required for proper branch protection (refer to Electrical Specifications). Individual circuit breakers could be required for each drive in a system. The size of the breaker required is dependent upon the gauge of wire used between the drive and the motor.
The drive contains an internal surge protector (MOV, P/N: P20V385) between the internal motor supply and ground. For hi-pot testing, you will need to temporarily remove JP100 (refer to Fuse Locations on the iXC4 Control Board ).
For CE compliance, connect an AC line filter as close as possible to the drive (refer to Minimizing Noise for EMC/CE Compliance).
WARNING: Verify that all ground connections are installed correctly before you apply power to the iXC4/XC4.
