Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: function-based → ≡
UPS units are defined by their identity-giving function of maintaining uninterrupted AC electric power supply, not by their internal mechanism (battery, flywheel, etc.). Different technologies can implement the same UPS function.

Identity-Giving Function
✓ done
⚠ not anchored
UninterruptedPowerSupplyFunction → UninterruptedPowerSupplyProcess
▼
COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
The identity-giving function is maintaining continuous AC electric power to protected equipment during power disturbances. This is distinct from basic power supply functions as it specifically includes continuity assurance and backup capability.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
Based on parent candidates, 'AC ELECTRIC POWER SUPPLY UNIT' would be most specific but is not in our enriched classes. 'electrical equipment class' is too generic. ElectricalEquipment captures that this is AC electrical apparatus without being overly broad like MaterialArtifact.

Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The UninterruptedPowerSupplyFunction is the minimal differentia that distinguishes UPS units from other electrical equipment - it specifically includes backup capability and continuity maintenance.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These parts are necessary for any UPS unit regardless of technology (battery, flywheel, etc.) to fulfill its uninterrupted power supply function.

LLM rationale:
UPS units take AC electrical power input and provide conditioned AC output with guaranteed continuity through backup systems during power disturbances.
