  1. Turn power ON at the circuit breaker panel.

  2. Using a solenoid type voltmeter, check that the voltages at the charging station’s terminal block are as listed in the table above.

    • Insert the meter probes into the holes at the top of each terminal block and check the input voltage.

    • If the voltages are not within 10% of the voltages in the table above, ensure the wiring has been properly connected. Refer to the detailed wiring diagrams in this chapter.

    • For grounding requirements, see the CP6000 Datasheet on ChargePoint Product Reference Documentation.

  3. Resolve any wiring issues and ensure voltages are correct.

    4. WARNING: Isolate the charging station at the circuit breaker panel before resolving any wiring issues.

  4. Turn power OFF at the circuit breaker panel.
