UPS Maintenance Checklist: Ensuring Power Continuity

A comprehensive UPS maintenance checklist is crucial for data center power infrastructure continuity. Regular maintenance can reduce surprise expenses and ensure power availability during emergencies.

Why this matters: Proper UPS maintenance is essential for preventing data center downtime, which can have significant financial and operational implications. By ensuring power continuity, organizations can protect their critical infrastructure and maintain business continuity.

Periodic visual inspections are a key component of any UPS maintenance program. These should include partial visual inspections to check for dust buildup, corrosion, and signs of overheating. Internal component examinations should also be conducted, but only by qualified individuals such as electrical engineers, facility electricians, or third-party experts to avoid electrical currents. Signs of corrosion, leakage, or swelling on batteries and capacitors should be looked for during these inspections.

Battery assessments are another critical aspect of UPS maintenance. Batteries should be checked for any signs of corrosion, leakage, or swelling, which would indicate the need for replacement. Internal battery connectors should also be inspected for corrosion damage or abnormal wear.

Capacitor checks are also important to verify that alternating current input and output capacitors, as well as direct current filter capacitors, are clean and free of cracks or swelling. Thermal scans using non-contact infrared thermometers or thermal imaging cameras can help measure surface temperature and detect any thermal anomalies. The temperature of air exiting fan-cooled UPS units should also be checked.

Load tests are used to verify the UPS's ability to power data center hardware during power failures and determine the maximum power it can support. However, these tests need to be planned carefully to avoid jeopardizing production workloads. Different types of load tests include steady-state load tests, harmonic analysis, and transient response load tests.

Additional tips for UPS maintenance include listening for unusual sounds, such as buzzing or grinding, during visual inspections. Paying attention to abnormal smells, like burning or hot plastic, can also indicate overheating or overload issues. Thermal imaging cameras are useful for detecting thermal variations and identifying cooling problems.

By following this comprehensive UPS maintenance checklist, data centers can ensure safe and efficient operations, reduce downtime, and prevent costly repairs. Regular inspections, battery and capacitor assessments, thermal scans, and load tests are all essential components of an effective UPS maintenance program. Qualified personnel should perform these tasks to maintain power continuity and protect critical infrastructure.
