Annual Uninterruptible Power Supply Maintenance

It’s important to schedule annual UPS system service to ensure that your UPS is running smoothly and reduce your need for UPS parts replacements. Mitsubishi Electric offers annual UPS maintenance as part of our standard contracts, and they include physical and electric inspections, as well as adjustments or recommendations for action.​

  • Visual inspection of internal components and wiring for loose connections, deterioration or damage – anything that could impact proper operation
  • Verification of proper software, control power devices, converter/rectifier operation, inverter operation, and cooling fan operation.
  • Test of static/internal maintenance bypass operation and system voltages and currents.
  • Verification of transfer operations and emergency (backup) mode operation and emergency power off (EPO test).
  • Verification that UPS is supporting the critical load.

With annual UPS preventative maintenance, we’ll provide a fast follow through with comprehensive documentation of findings, required UPS repairs, and adjustments or remedial action plans when necessary.

Quarterly / Semi-Annual UPS Maintenance

While annual service is the suggested minimum, we recommend our technicians come out and perform UPS system service at least twice a year to ensure your system is functioning properly. There may also be value in quarterly inspections, especially as your equipment ages.


Quarterly/semi-annual UPS preventative maintenance includes:

  • Physical environment inspection for any elements that could impact operation.
  • Verification of proper software versions and adjustable parameters
  • Verifications of proper cooling fan operation and display of system values
  • Review of event or fault history
  • Verification UPS is supporting the critical load and no alerts/alarms are present

As with annual UPS preventative maintenance, we’ll generate a test report and discuss any necessary UPS repair service while we’re onsite.
