Where a wrong selection would matter
Incoming-goods check
Read both the packing label and the product label for LR3D04. Verify the suffix, ordered quantity, terminal or connector form and any included parts before accepting LR3D04 into inventory.
Commissioning evidence
Install LR3D04 only after isolation and site-specific checks. Record connections, protective settings, program backups, relay logic, calibration or battery tests as applicable to LR3D04. The final test should identify the installed LR3D04 by its complete designation.
Maintenance should retain the LR3D04 document revision, service history, supplier confirmation and any accessory list. These records make future enquiries for LR3D04 less dependent on a potentially ambiguous photograph.
