Case Study #123 | Crisis averted: UPS battery install Mitsubishi UPS 2033D 30kVA
Product | 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 (CPP™) 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 CPP™ 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 CPP™ 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. |
