Eaton reports 50 5PX 3 kVA units, two 9SX 5000i units and one 93PM at Winchester University. Equipment record: Eaton 5PX 3000 VA, companion identifier Eaton 9SX 5000i. Decision: Use common telemetry and battery-condition records across the 5PX, 9SX and 93PM fleet while retaining model-specific runtime and service limits.
Fifty-three UPS positions, three equipment classes
The fleet combined distributed rack UPS units with a larger three-phase position. Eaton’s case reports up to 20 minutes of runtime on the 5PX population, Advanced Battery Management warning as much as 60 days before battery replacement and more than 1,500 recorded power disturbances or interventions during a year. The engineering value came from making those events comparable without pretending every UPS had the same battery or duty.
For Eaton 5PX 3000 VA, the applicability boundary is anchored to 50 5PX units, 2 9SX units and part Eaton 9SX 5000i. No worked input is added to these published points. The exact equipment record still requires confirmation at the installed unit.

Runtime, warning and event quantities
The controlling numerical record is: 5PX fleet count: 50 5PX units; 9SX 5000i count: 2 9SX units; 93PM count: 1 93PM unit; Reported 5PX runtime: 20 min; ABM warning horizon: 60 days; Recorded disturbances and interventions: 1500 events/year. Each value has a defined source or assumption status in the engineering ledger. Values from different configurations are not combined as though they came from one installed system.
| Engineering parameter | Value | Evidence status |
|---|---|---|
| 5PX fleet count | 50 5PX units | Published OEM value |
| 9SX 5000i count | 2 9SX units | Published OEM value |
| 93PM count | 1 93PM unit | Published OEM value |
| Reported 5PX runtime | 20 min | Published OEM value |
| ABM warning horizon | 60 days | Published OEM value |
| Recorded disturbances and interventions | 1500 events/year | Published OEM value |
The 53-unit fleet average is about 28 events per UPS-year if 1,500 events are divided evenly. That average is a triage index, not a statement that each device experienced the same event count. Unit-level event density, temperature, load and battery warning history remain the usable maintenance evidence.
Turning 1,500 events into a rate
The worked check uses fleet event index = 1,500 events / 53 UPS positions. With 50 5PX units, two 9SX units and one 93PM, the result is 28.3 events per UPS-year as a fleet index. Positions above the index merit review, while a low count does not override a battery warning or failed test. The arithmetic is reproducible, but it remains a design check until the listed inputs are confirmed at the equipment.
The 28.3 events per UPS-year as a fleet index result follows from fleet event index = 1,500 events / 53 UPS positions. If the 2 9SX units input changes, this check is repeated rather than carrying the earlier result into a different operating state.

One condition record without one generic threshold
A 5PX runtime value cannot be applied to the 9SX or 93PM. Each model keeps its own battery topology and load reference, while the common record stores date, event class, temperature, load percentage, battery warning and response.
The 60-day warning horizon can create maintenance lead time only when the alert reaches an owner. A warning without ticket ownership, acknowledgement and a replacement decision is a display value, not risk reduction.
Trend review distinguishes a noisy branch circuit from a battery issue. Repeated transfers, overloads or temperature excursions are routed to the relevant electrical or environmental owner instead of being counted as generic UPS incidents.
| Path | Technical consequence | Disposition |
|---|---|---|
| Apply the stated engineering decision | Use common telemetry and battery-condition records across the 5PX, 9SX and 93PM fleet while retaining model-specific runtime and service limits. | Selected basis |
| Generic model substitution | Select by family name or rating alone, without confirming the exact configuration. | Not selected on the stated evidence |
| Unverified operating assumption | Treat a design assumption as though it were a site measurement. | Reconsider only if the input changes |
Eaton and Powerware UPS service across Canada covers field measurements and service work for Eaton 5PX 3000 VA.
Confirm availability and catalogue details for Eaton 5PX 3000 VA or Eaton 9SX 5000i on the legacy Powerware replacement-battery options page.
The Eaton 5PX 3000 VA decision retains part Eaton 9SX 5000i, the 28.3 events per UPS-year as a fleet index calculation result and the manufacturer-published 50 5PX units point in one equipment record. Applicable OEM instructions, qualified electrical authority and the installed single-line or wiring record remain controlling for any executable work.
Sampling a mixed fleet
Acceptance of Eaton 5PX 3000 VA depends on five recorded checks:
- Reconcile all 53 asset identifiers to model, location and monitored address.
- Retain model-specific load and runtime fields for 5PX, 9SX and 93PM.
- Test that ABM warnings create an owned notification before the stated horizon expires.
- Compare event rate by position rather than relying on the fleet average alone.
- Sample loaded operation and battery condition against the exact unit record.
The Eaton 5PX 3000 VA record is not accepted if part Eaton 9SX 5000i does not match, the calculation does not reproduce 28.3 events per UPS-year as a fleet index, or the final operating state is not recorded. The equipment returns to the approved safe state when a check stops, and the unresolved condition remains open without an invented repair result.

Battery prediction tied to the exact unit
The mixed fleet becomes maintainable when every event resolves to an exact UPS and battery record. The 28.3-event index highlights outliers, while model-specific warnings and measurements control the service decision.
Decision rule: Use common telemetry and battery-condition records across the 5PX, 9SX and 93PM fleet while retaining model-specific runtime and service limits. A different model, load, voltage, battery string, software version or operating state requires a new check against the applicable manufacturer record.
