Uninterruptible power supply (UPS) maintenance checklists for the quarterly and annual rounds: 2 free lists, 10 items and 13 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against NEC (NFPA 70); the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Uninterruptible power supply (UPS) quarterly maintenance checklistquarterly
- Every quarter, walked with the panel and room checks since the UPS shares its space and cooling with the gear it protects. Run by: The electrical or facilities tech on the quarterly round, working at the unit without transferring critical load.
- Uninterruptible power supply (UPS) annual maintenance checklistannual
- Once a year, scheduled when critical loads can be moved to bypass and when a real discharge test won't leave equipment unprotected. Run by: The UPS service tech on the annual, coordinated with a maintenance window for the protected load.
What most often fails on an uninterruptible power supply (UPS)
- Event log never pulled, so a battery throwing warnings for weeks is only discovered once it has already failed.
- Room or cabinet ventilation and filters ignored, letting battery temperature climb and quietly shortening battery life.
- Load crept up as equipment was added downstream, so the displayed runtime is a fraction of what everyone assumes.
- Battery string judged by overall voltage while one weak block drags the real backup time far below the display.
- Bypass never actually exercised, so the day it's needed for service nobody knows whether the transfer is clean.
- Discharge test skipped, leaving runtime a spec-sheet number never proven against the aged batteries actually in the cabinet.

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which uninterruptible power supply (UPS) maintenance rounds do these checklists cover?
- Uninterruptible power supply (UPS) quarterly maintenance checklist (quarterly): Every quarter, walked with the panel and room checks since the UPS shares its space and cooling with the gear it protects. Uninterruptible power supply (UPS) annual maintenance checklist (annual): Once a year, scheduled when critical loads can be moved to bypass and when a real discharge test won't leave equipment unprotected.
- Who runs the uninterruptible power supply (UPS) maintenance round?
- The electrical or facilities tech on the quarterly round, working at the unit without transferring critical load. The UPS service tech on the annual, coordinated with a maintenance window for the protected load.

- Which standards is uninterruptible power supply (UPS) work verified against?
- NEC (NFPA 70), published by the National Fire Protection Association. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (10 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
