Check Voltages

IMPORTANT: Ensure that Neutral connects to ground in the system per applicable codes.

The following table lists the expected input voltage measurements.

Input Voltage Measurements

Measure Between

  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. Turn power OFF at the circuit breaker panel.
