UPS Startup

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

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.

Commissioning

Commissioning typically includes additional testing such as UPS battery testing, load-bank testing and burn-in testing. UPS Commissioning also often involves a higher level of testing known as Integrated System 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

Technicians verify the proper installation of your equipment.

This can vary depending on the customer, location, type of UPS, etc. Technicians are responsible for any testing that verifies that the UPS system will perform. This includes infrared scanning of electrical equipment and other initial onsite tests.

Refer to our Pre-Startup Checklist for a complete list of what is required for an effective and safe startup.

Every UPS is tested prior to shipment and furnished with a signed factory test report.

Additional factory 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.

Standard testing includes measurement of steady state characteristics, measurement of transient response, output transfer testing, UPS overload testing, and AC input failure recovery.

Mitsubishi Electric can also offer support on commissioning testing and integrated systems testing.

At a factory witness test, customers can expect to see their equipment go through simulated load conditions to test and verify performance in all possible conditions, especially adverse scenarios.

Pre-testing in our lab environment enables necessary last-minute tweaks possible at the factory and eliminates on-site troubleshooting.

Learn more about why you should invest in a factory witness test.

Mitsubishi Electric provides UPS training for end users called First Responder Training, which is geared towards day-to-day UPS operation and properly assessing the system’s performance and trends - Contact us!

Equipment should be stored in environmentally controlled and conditioned spaces.

Water or condensation could lead to corrosion, risk of shock, shorts on circuit boards, or unplanned outages/ load losses. Without proper environmental control, there is a risk of foreign material contamination.

Some best practices include refraining from storing the UPS or batteries in areas open to the elements and following all storage requirements listed for each piece of equipment.

Storage requirements vary between UPS models so be sure to consult your specific model’s owner’s manual or refer to our Technical Support line if you have any questions.

An improper storage and installation environment will deteriorate the insulation, shorten component life, cause corrosion and equipment malfunctions, as well as potentially void your warranty.

Each test conducted during a preventative maintenance visit offers valuable insights into the overall health of the system. We analyze this data to monitor individual components and identify potential failures before they occur.

Additionally, we routinely cycle infrequently used components to confirm their readiness and ensure full functionality when needed.  

UPS preventative maintenance is vital to ensure that your UPS system performs at its highest reliability and efficiency.

While Mitsubishi Electric UPS systems are the most reliable UPS on the market, the only way for truly uninterrupted operation is to enroll in regularly scheduled maintenance visits.

With our support, preventative maintenance becomes routine and an integral aspect of overall system reliability. Staying up to date on lifecycle parts replacements and monitoring the health of your equipment is also essential to achieve maximum uptime and prolong the life of your equipment.

There are many factors that could cause a UPS failure, such as a lack of maintenance and your UPS's load factor.

Maintenance

Maintenance is the most common cause of UPS failure. Periodic maintenance visits ensure that your system is functioning at its highest reliability and has a healthy service life.

During visits, authorized technicians perform visual inspections and other tests to identify any potential problems and mitigate repair. Lifecycle part replacements are also incredibly important to keep in mind, especially as your UPS ages and parts reach the end of their design life.

Service from Mitsubishi Electric ensures timely replacement and management of these updates.

UPS Load Factor

Adding more loads to your equipment or operating at a higher load capacity could have adverse effects on your UPS. This is why application engineering is so important.

If you are considering increasing the load on your UPS or adding new equipment to your system, you should consult with our team to evaluate.

There is some overlap between both types of preventative maintenance, but here are the main differences:

• Major preventative maintenance is often synonymous with annual preventative maintenance and is typically more thorough. The UPS must be taken offline and transitioned into maintenance bypass to test functionality. 
• Minor preventative maintenance is often synonymous with quarterly/semi-annual and typically involves visual inspections for anomalies/irregularities and a review of event or fault history.

It is recommended to have a method or procedure in place to shut down the UPS for maintenance.

If you’re unsure how to do this, the technician on site can help! Our First Responder Training is also a helpful way to familiarize your team with the equipment.

Additionally, if your site requires security access, we’d greatly appreciate you being proactive to avoid delaying or rescheduling maintenance.

While N+1, catcher systems, and other configurations add layers of redundancy to the design, a UPS system still requires maintenance to ensure optimal performance.

It is not ideal to be in a situation where a critical load is transitioned to another UPS or set of UPS systems when an issue occurs, as it reduces redundancy of backup power.

The down UPS(s) will then need to be repaired, and while being repaired, the redundant UPS systems are the only ones holding the critical load.

If an issue then occurs with the redundant UPS, the critical load(s) could be dropped. Regular maintenance ensures that the entire UPS system remains in top condition to limit the potential for issues to arise.

1. Note the Serial Number and any active alarm/fault codes on the UPS screen.
2. Call Technical Support (1-800-887-7830, option 1) with this information. Our Technical Support Engineers can either guide you through resetting the UPS or taking appropriate next steps.

Mitsubishi Electric also provides first responder training available for those who manage sites with our UPS. This training equips them to understand and perform some basic troubleshooting techniques.

UPS software is verified during startup and preventative maintenance.

While software updates are not a common need, regularly performed preventative maintenance ensures that your system’s software is up to date.

Regular preventative maintenance visits is the best way to ensure your software is up to date.

You can also call Technical Support (1-800-887-7830, option 1) to guide you through verifying if your UPS has the necessary software updates.

If a UPS software update is needed, then a service technician can be dispatched to your site for installation.

The system will need de-energized for annual maintenance visits, but not for semi-annual visits.

UPS battery maintenance is heavily dependent on what type of batteries your UPS system utilizes. Mitsubishi Electric can provide maintenance on VRLA, VLA (wet cell), Pure Lead, flywheel, and lithium-ion batteries.

Different chemistries have varying characteristics and life spans that need to be planned for accordingly.

Mitsubishi Electric’s battery maintenance services include annual and quarterly /semi-annual maintenance visits, battery monitoring and replacement services.

Thermal runway begins when the heat generated within a battery exceeds the amount of heat that is dissipated to its surroundings.

As excessive heat reaches critical limits, the battery system will encounter events that will lead to an uncontrollable self-heating state.

There are many contributing factors that could lead to this: ambient temperature, age of the battery, excessive float charging voltage, and overcharging.

Being on alert for other battery anomalies can only further prevent thermal runaway. To prevent it, invest in regularly scheduled maintenance for your batteries and a battery monitoring system that will ensure that you are always aware of the condition of your batteries.

The expected lifespans for each UPS battery chemistry we offer are:
