UPS Maintenance, Replacements & Upgrades

The key to an efficient and reliable UPS is careful upkeep. Mitsubishi Electric’s multi-faceted maintenance services and power supply repairs keep your uninterruptible power supply running at optimal performance, while identifying potential threats. Our comprehensive testing makes us a leading performer in UPS parts replacements and maintenance services. Our customer service team will work with you to determine the ideal plan to service your equipment.

 

With UPS support, preventive maintenance becomes predictive – we’ll help you know what updates and upgrades are coming so you have replacements installed onsite before you need them. UPS support and maintenance may vary by contract, but generally includes component verification, fan trending, thermal scans, and IEEE battery checks. Field service technicians use industry leading tools, meters, and expertise to troubleshoot, diagnose, and repair system irregularities found in the steps detailed below.

Annual UPS Maintenance

It’s important to schedule annual service to ensure that your UPS is running smoothly and reduce your need for UPS parts replacements. Mitsubishi Electric offers annual system 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 preventive 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 system maintenance at least twice a year to ensure your system is functioning properly and will back up power in the event of loss or fluctuation. There may also be value in quarterly inspections, especially as your equipment ages.

 

UPS quarterly/semi-annual preventive 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 preventive maintenance, we’ll generate a test report and discuss any necessary UPS repairs while we’re onsite.

Battery Maintenance, Replacement & Upgrades

Batteries are a vital component of any UPS and considered the last line of defense against expensive downtime. They are also highly vulnerable when not managed properly. Mitsubishi Electric offers maintenance, monitoring and replacement services that keep your batteries fully charged and your UPS fully operational. From large-scale change outs to single string or individual battery replacements, Mitsubishi Electric is your DC power partner.
