Spare Parts Inbound: The Receiving Inspection That Prevents Install-Day Regret

Install-day surprises almost always could have been caught at receiving. The routine below takes minutes and pays for itself the first time it stops a wrong unit from being installed.

The receiving sequence

1. Photograph before opening — packaging damage decides any freight claim before contents are touched.
2. Label match: part, revision and market variant (denomination tables and language packs are market-specific, and revision beats part number every time).
3. Physical audit: connector shell, pin visibility, mounting holes and firmware sticker date.
4. Bench verification — power the module up on the test rig before the shelf accepts it; a module that never passed a bench test is inventory risk, not inventory. Documented incoming inspection of this kind is exactly what ISO 9001 quality-management practice expects — if your customer asks, the records answer.
5. Shelf record: source batch, test result and install-by notes so FIFO actually works.

The two traps that survive casual inspection

• Correct part number, wrong revision (internals change under the same label).
• Correct revision, wrong market variant — the unit “works” but misbehaves on local denominations.

RMG ships parts with the four-point documentation set that feeds this checklist — the fields to expect are defined in the compatibility guide, and the inbound paperwork pairs with the shipping-and-papers guide, both in the RMG Knowledge Base.
