Connect Wiring
CAUTION: Use copper conductors only.
Do not provide GFCI
Ground-Fault Circuit Interrupter protection at the panel. The charging station has built-in GFCI Ground-Fault Circuit Interrupter protection.
In areas with frequent thunderstorms, add surge protection at the service panel for all circuits. Use new circuit breakers only.
Ensure all power and ground connections (especially those at the breaker) are clean and tight. Remove all oxide from all conductors and terminals before connecting wiring.
Although neutral is not used by charging stations, system neutral must be bonded to ground so that all line to ground voltages are defined.
Grounding Requirements
CP6000 charging stations must be connected to a grounded, metal, permanent wiring system. An equipment-grounding conductor must be run with circuit conductors and connected to an equipment-grounding terminal on the charging station.
A grounding conductor that complies with applicable codes must be grounded to earth at the service equipment or, when supplied by a separate system, at the supply transformer, or may be grounded to an earth electrode. Ensure the grounding conductor complies with all applicable codes.
