Where a wrong selection would matter

Incoming-goods check

Read both the packing label and the product label for RPM42BD. Verify the suffix, ordered quantity, terminal or connector form and any included parts before accepting RPM42BD into inventory.

Commissioning evidence

Install RPM42BD only after isolation and site-specific checks. Record connections, protective settings, program backups, relay logic, calibration or battery tests as applicable to RPM42BD. The final test should identify the installed RPM42BD by its complete designation.

Maintenance should retain the RPM42BD document revision, service history, supplier confirmation and any accessory list. These records make future enquiries for RPM42BD less dependent on a potentially ambiguous photograph.
