Technical data to check

Fit decision

Receiving inspection

At receipt, compare SR2B121B on the package with SR2B121B on the product marking. Inspect terminals, housing and supplied accessories, and photograph the rating label for the maintenance file.

Installation and service record

Before fitting SR2B121B, isolate the relevant circuit and identify every conductor or busbar connection. Preserve settings or program data where SR2B121B participates in a programmable system. After installation, carry out a controlled functional test appropriate to SR2B121B and record the result.

For a repeat order of SR2B121B, keep the complete suffix, source document revision, equipment tag, accessories and any measured site limits together. This prevents a visually similar variant from being substituted for SR2B121B without a technical review.
