Use in the project example

What the sources describe

The cited Eaton 93E manual provides an installation checklist covering electrical, control/EPO, environmental, enclosure, cleanliness, access, and workspace items and places completed-checklist retention before authorized preliminary checks/startup. Build Pearls makes the exact-model checklist and OEM pre-start acceptance a visible energisation hold point. Authorized startup arrives against incomplete wiring, control/EPO, environmental, enclosure, cleanliness, or access conditions.

Evidence to confirm

Purchased-equipment UPS installation checklist
Authorized OEM service engineer · Before the relevant work begins
The checklist matches the installed model/revision and every applicable electrical, control, enclosure, environmental, access, and cleanliness item is resolved.
OEM pre-start checklist acceptance
Authorized OEM service engineer · Before the relevant work begins
The authorized startup representative accepts the retained installation checklist and preliminary conditions.

Conditions to resolve before proceeding

The checklist belongs to a different model, voltage, or revision.
HVAC, EPO, controls, covers, cleanliness, or workspace are treated as post-start punch items.
