Nationwide Power is the leading provider in the critical power supply industry. Our core business is the sales and service of uninterruptible power supplies and UPS batteries, along with supporting other critical power components such as emergency generators, switch gear, and HVAC.

On a monthly basis, we publish critical power related case studies, highlighting best practices and quality standards. In this month’s case study, we feature an account we recently acquired, where the previous UPS service provider may not have had the highest standards in quality and performance:

 

Product

UPS battery install (HRL12280WFR) for Mitsubishi UPS 2033D 30kVA

 

Application

Manufacturing Data Center

Synopsis

New client hired Nationwide Power to inspect and maintain their Mitsubishi UPS 2033D-30kVA, which provides critical power for an existing data center.

Preliminary Actions

Upon inspection, our Critical Power Professional (CCP™) found a battery cable inside the battery cabinet, where the cable’s lug eyelet had melted due to improper torquing /fastening to the battery insert by the previous service company.

 

If left in its current condition, the cable could have melted during an outage causing a domino-effect including breaking the string’s integrity, dumping the load, and possible risk of fire.  It could have also caused a ground fault which would have not only dumped the load, but also damaged the UPS. 

Resolution

Our CCP™ team is equipped with some basic universal repair parts, and in this case a spare battery cable saved the day and was promptly replaced.  By being prepared, our CCP™ left the battery string in a condition that no longer presented a safety threat and left the UPS in proper working condition. 

 

Ongoing and regular UPS battery inspections are recommended by a qualified Critical Power Professional™.

Root Cause

The damaged battery cable appears to be the result of negligence from the previous service provider.  This should have been identified and repaired in previous inspections and is a basic element of any quality maintenance inspection.
