Grounding and Wiring

This appendix describes the grounding requirements and wiring diagrams for a CPF32 charging station. For full specifications, refer to theCPF32 datasheet at: ChargePoint Product Reference Documentation.

Grounding Requirements

The voltage of either line, relative to ground, must not fall below 80 volts. Because the voltage of either line relative to ground must not be allowed to fluctuate, use only center-grounded systems. Neutral is not used to power the station but must be properly connected to ground, at the panel or transformer, to provide the necessary voltage reference relative to ground.

Wiring Diagram

The following illustration describes the wiring for installing a CPF32.

Note: The panel requires a 16 A breaker.

 

(a) Neutral bus

(b) Ground bus

(c) Main breaker

(d) RCB
