Scope of Maintenance

This topic describes the scope and responsibilities for the maintenance of CT4000 charging station.

Responsibility for Maintenance

The ChargePoint charging station needs preventive maintenance over its lifetime. ChargePoint’s network connection monitors for system health and sends an alert when corrective maintenance might be required.

Maintenance can be performed by ChargePoint technicians for an additional fee. Otherwise, customers can send their own technicians for training to become approved by ChargePoint to perform the work. For more information on becoming a ChargePoint certified installer or service technician, see Become a Certified ChargePoint Installer.

Site Manager’s Responsibilities

The site or facility manager where the ChargePoint charging station is installed has a few duties for general site maintenance:

  • Ensure the station is free of debris or any substance blocking the front and rear vents.

  • Keep snow below 0.25 m (10 in) to ensure proper ventilation.

  • Check each station monthly for vandalism or damage. If the station is marked, contact ChargePoint for replacement signs. If the station appears damaged, contact ChargePoint for a service visit.

  • Check each charging cable monthly for any signs of wear or damage. If a cable appears damaged, contact ChargePoint for a service visit.

Do not pressure wash the charging station. Pressurized water can damage the system. Use a damp cloth to clean the charging station.

Preventative Maintenance

Perform these recommended service checks at the intervals listed below.

RISK OF SHOCK. Before performing any procedure, the technician must disconnect the power to the charging station at the service panel. Follow local code to de-energize the applicable circuit and lockout/tagout the upstream breaker before proceeding. Use a multimeter and check that the power is off. Keep power off for the circuit until all cover panels are correctly reinstalled and the work is complete. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY, LOSS OF LIFE, OR PROPERTY DAMAGE.

Yearly Maintenance

For all installations:

  • Check signs for marks or fading. If needed, refer to appropriate service guide and replace the product.

  • Use a damp, lint-free cloth to wipe down the outside surfaces of the station, including the cables, outer surfaces of the connector, and screen.

  • Check the exterior of the charging station for any signs of corrosion or damage. Contact ChargePoint if damage is found.

  • For installations with a screen, verify that the screen and the buttons are functioning properly. If needed, refer to appropriate service guide and replace the screen.

  • Perform all safety testing required by law. Refer to local regulations for details.

    • Check charging cables and connectors for any degradation or damage. If needed, refer to appropriate service guide and replace them.

    • Check the strain relief for any damage. If damage is found, refer to appropriate service guide and replace the head assembly.

  • For installations with a Cable Management Kit, verify that the retractor for cable management kit is not frayed and successfully retracts. For problems with the retractor, contact ChargePoint for assistance.

For pedestal mount installations:

  • Verify that the pedestal is secured to the ground and does not wobble. If loose, disassemble the station and tighten the bolts to 160 Nm (1416 in-lb). Refer to the Installation Guide for additional information.

For wall mount installations:

  • Verify that the installation does not shift or wobble. If the charging station is not fully secured, contact ChargePoint for assistance.
