Maintenance

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

  • Follow local code and refer to the site lockout/tagout procedure and Service Guide to power off and de-energize Power Hub.
  • If you find any damages, excessive wear, part impairment, or improper functioning, contact ChargePoint for assistance and replacement parts.
  • Use only ChargePoint authorized parts and refer to the Service Guide for part replacement instructions.
  • If the charging station is not installed, commissioned, or serviced by a ChargePoint Certified Technician using a ChargePoint-approved method, it is excluded from all ChargePoint and other warranties and ChargePoint is not responsible.
  • You must be a licensed electrician and complete the training at https://www.chargepoint.com/partners/training-certification to become ChargePoint certified and to access the ChargePoint web or app-based installer tools.

Site Manager’s Responsibilities

The site or facility manager has a few duties for general site maintenance:

  • Establish site lockout/tagout procedure per local code and in compliance with the Service Guide.

  • Maintain an up-to-date copy of the site's as-built and single line diagram (SLD) that includes the naming of all control elements (circuit breakers, fuses, overcurrent devices, and disconnect switches). Documentation to include but not be limited to the localizations, permanent panel schedules, and means or methods required to de-energize the charging station.

  • To ensure proper ventilation, make sure nothing is blocking each station's exterior vents, including any snow buildup (remove if present).

  • Regularly clean each station's exterior with a damp and lint-free cloth to prevent the accumulation of debris, dust, or dirt. Perform this maintenance more frequently in high pollution environments.

Do not pressure wash the station. Water pressure can damage the station.

  • Check each station (including the charging cable and connector) monthly for vandalism and any signs of wear or damage.
