What happens at receiving?

Specify ZENL1121 without dropping punctuation or suffixes.

Compare the exact label and data sheet for ZENL1121 with the approved installation drawing. The verified table is a starting point, not a full engineering approval.
Which parameters can vary?
The exact ZENL1121 marking matters because similar codes can identify other ratings, options or roles. Do not transfer a voltage, current, contact arrangement, ingress rating or protocol from another designation to ZENL1121. Where the table gives a family-level description, confirm the unit-specific value on the manufacturer's current document.
How should the quote be checked?
Ask for the current data sheet and installation document for ZENL1121. Check lead time, regional availability, accessory inclusion and documented status. If the manufacturer offers an alternative to ZENL1121, compare the interface and safety consequences before authorising it.
