Three-stage review
- 01 / Identify Use the complete ZCMD21 designation in the purchase order and on the equipment tag. Check the supplied label against ZCMD21 before booking the item into stock.
- 02 / Compare For ZCMD21, compare the table above with actual duty, supply, connections and mounting. Check mounting, head orientation and travel. A shared category image must not be used as proof of exact ZCMD21 construction.
- 03 / Accept After installing ZCMD21, record the inspection and functional test. Store configuration, relay setting or controller program information with the ZCMD21 equipment record when relevant.
Evidence to retain
Keep the order confirmation, packing-label photo, manufacturer document revision, equipment location and acceptance record for ZCMD21. If a future order requests ZCMD21, these records help distinguish an exact repeat from a merely similar-looking alternative.
If ZCMD21 is part of a control or protection system, the responsible engineer should also preserve settings, program backup, terminal schedule and test evidence. A replacement that changes behavior must be assessed before ZCMD21 is energized.
