A UPS maintenance contract fixes, in writing, how often the UPS is maintained, how fast someone responds when it fails, what is included and what the reports show. A good one is easy to compare and hard to misread.
| What happens | What you receive |
|---|---|
| Site survey: every UPS, battery string and bypass is listed | The equipment list with models and ages |
| Baseline visit: full maintenance and battery readings | The baseline report and any urgent findings |
| Schedule agreed: visits, battery tests, thermal scans | A calendar for the year |
| Response terms agreed for each site | Response times and the emergency line in writing |
| Each visit reported against the baseline | Trends, open items and a replacement outlook |
For a critical UPS, two full visits a year is the common baseline, with battery readings in between. Vertiv's field data is the strongest argument for it: UPS with two preventive visits a year had an MTBF 23 times higher than UPS with none, and monitoring the battery strings more than doubled MTBF again over maintenance alone. EnerSys's VRLA manual requires annual preventative maintenance by a trained technician and quarterly ohmic readings, and Eaton's guidance adds monthly filter checks and quarterly thermal scans; the contract should say which of these it covers.
Coverage changes, and the contract should say how. Eaton's end-of-service-life table shows the stages a model goes through: active full support, then mature with best-efforts parts and product replacement recommended, then retired with no contract coverage and only time-and-materials service, then obsolete with no service or parts. A contract on an older UPS should state which stage the model is in, how parts are sourced, and what happens if a part cannot be found; see modernization and replacement planning.
Line them up on the same equipment list and the same questions: visits per year and what each covers, battery testing included or extra, response time to site and the hours it applies, parts and labour included, emergency calls included or billed, and what the report contains. A lower price that drops a visit or excludes batteries is usually not cheaper by the end of the year. Makers frame their own programmes the same way; Tripp Lite describes its service as covering the UPS from initial startup to annual service agreements and preventive maintenance.
We write maintenance contracts for three-phase UPS of every major brand, with the visits, battery testing, response times and reports set out in writing for each site. Quotes go out within 4 business hours. A technician reaches sites in Montreal, Quebec City, Toronto or Ottawa the same day, and other Canadian sites within 24 to 48 hours; the emergency line never closes. For data-centre service by brand, see UPS service for data centres.
Battery testing usually is; replacement is usually quoted when due, because its cost depends on the string. The contract should say which.
Yes. Each site keeps its own equipment list, schedule and response terms.
The contract states how parts are sourced and what happens if one cannot be found, and the reports track a replacement plan.
