UPS Testing, Startup and Commissioning

Mitsubishi Electric provides comprehensive UPS testing, including startup and commissioning testing for industry-leading reliability.

Ensure your UPS is ready for action

with factory test reports, UPS startup testing, field testing & more from certified technicians


Unlike other UPS suppliers, every UPS from Mitsubishi Electric is tested prior to shipment and furnishes it with the signed factory test report. Additional UPS testing, such as load bank testing or an optional Factory Witness Test can also be performed virtually or at the Warrendale, PA facility with the end user present.


Proper UPS testing is essential to establishing baseline metrics and ensuring the highest level of performance. Pre-testing in a lab environment enables necessary last-minute tweaks at the factory and reduces on-site troubleshooting, further promoting a smooth system integration.

Critical UPS Testing, Startup and Commissioning Levels


Level 1 | Factory UPS Testing

We perform comprehensive UPS testing on our modular prior to shipment, delivering our industry-leading reliability every time.


Equipped with two test labs with 3MW resistive and 375kVA reactive load banks available, standard testing uses factory-provided batteries and simulates real-world scenarios to verify performance and efficiency under varying conditions.


Customers are then provided with a factory test report to verify seamless installation and commissioning. Standard UPS testing includes:

  • Measurement of steady state characteristics (efficiency & input voltage performance)
  • Measurement of transient response
  • Output transfer test
  • UPS overload test
  • AC input failure recovery

Customers can also request additional tests, such as a Factory Witness Test where they are invited to view real-time data and results at our Factory and Test Labs or virtually.

Mitsubishi Electric provides factory testing and reports before our systems get to your floor.

“ The tests today really defined how Mitsubishi differentiates itself to others in the marketplace, and it was really clearly stated how Mitsubishi uses different components and perhaps even better components to reduce it’s footprint by increasing it’s efficiency overall... ”

- Stef Lidington, Logistics Manager at SourceBlue

Trust Mitsubishi Electric technicians to handle UPS installation and startup.

Level 2 | UPS Installation & Verification

Although Mitsubishi Electric doesn’t perform UPS installation, our team ensures confirmation of proper environment and installation, verification of torque, proper cable sizing, and identifies any clearance issues. At this point, we can also perform a lithium-ion battery installation, if applicable to your system's startup.


Level 3 | UPS Startup


After UPS installation, an authorized technician will perform UPS startup to confirm the system has been installed properly. This is the best way to enact proper procedures and ensure adherence to warranty protocols. It's also an additional benchmark for performance data and an opportunity for onsite training.


UPS startup focuses on powering up the UPS and running it through a series of checks and balances. These often include infrared scanning of electrical equipment and initial onsite tests.


Ahead of each UPS startup, there is a checklist that serves as a resource to ensure that all items required for an efficient experience have been completed. This includes confirming that all equipment is free of contamination, temperature and humidity are optimal for certain types of battery installations, and that all your site requirements are met to make for a safe and compliant UPS startup.

“ Your start up team and product have been superb through the installation, warranty, service, Product Mangers: the team did a really good job. ”

- Doug Hollenbaugh, Sr. Manager, Real Estate Facilities Operations at Lumen

Leverage UPS testing to ensure your system is running smoothly.

Level 4 | Commissioning Testing


Commissioning testing can be done before integrating your UPS system with the rest of your equipment. This type of UPS testing helps identify any areas requiring maintenance or other updates and can be done at any point once the system is up and running. It can include any number of performance tests, but generally involves the following: 

  • UPS battery testing: Battery run-down evaluations to check connections and cells and capacity testing to ensure the size of the battery matches the output needed for the system.
  • Load-bank testing: Verify that load carrying characteristics meet specifications.
  • Burn-in testing: An extension of load bank testing that runs on an expendable load to ensure adequate performance. Including heating circuit paths, infrared scanning of our electrical equipment’s components, both internal and external to the UPS, identify any premature failure points.

Level 5 | Integrated Systems Testing


This measures not only the performance of your UPS system, but also how it affects and integrates with the other equipment in your facility, including:

  • Generator, grounding system and breakers
  • Automatic transfer switches (ATS)
  • Power-distribution units (PDU)
  • Cooling systems 
Mitsubishi Electric provides load bank testing, UPS battery testing and infrared scanning of electrical equipment.

Establish a Maintenance Routine after UPS Testing


Monitoring equipment performance doesn’t stop after initial test phases are complete. Routine maintenance and UPS testing allows for documentation of performance over time, which can help identify issues or predict when repairs may be needed. This can include infrared scanning of electrical equipment, UPS battery testing, harmonics testing, issue mitigation testing, parts cleaning and replacement, documentation of system changes and issues for warranty claims, and more.


A trained Mitsubishi Electric technician can administer these tests for you and provide recommendations for maximizing your UPS system's capabilities. We recommend preventive maintenance visits twice a year, as well as enrolling in a service maintenance contract to stay on top of maintenance and parts replacements. A service contract also gives you priority emergency response times, and discounts on parts and labor.
