21747-040-00 is a Bently Nevada extension cable used within the Bently Nevada proximity measurement system. It provides the specified extension cable function while retaining the complete order code, hardware execution and receiving-system compatibility during replacement. Its documented cable length is 4.00 metres (157 inches).
Loop Wiring: 21747-040-00 performs the extension cable function within the Bently Nevada 3300 transducer cabling. The retained documentation identifies cable length as 4.00 metres (157 inches); apply that value only to this documented execution.
Match the complete label, hardware form and functional position before transferring any setting, cable or termination from the removed unit.
Platform Review: approve 21747-040-00 only for the documented Bently Nevada proximity measurement system. Compare rack, carrier or panel generation, connector keying, terminal numbering and all paired assemblies with the installation drawings.
Photograph both sides and the installed position before removal so revision markings, jumpers, addressing and channel allocation can be reconstructed accurately.
Validation Steps: isolate the equipment, remove stored energy and inspect the receiving hardware before installing 21747-040-00.
Restore power in the approved sequence, review status and diagnostics, then test every affected control, signal, relay, communication, protection or monitoring path against the commissioning record.
Verify that the supplied item is marked 21747-040-00 and that its extension cable form, faceplate, connectors and printed revision agree with the approved Bently Nevada 3300 transducer cabling receiving record.
Retained product evidence for this execution includes Cable Length: 4.00 metres (157 inches); Armor: Without armor. Use photographs of the label and installed position to resolve ambiguity before shipment or installation.
For 21747-040-00, provide the installed Bently Nevada proximity measurement system, required condition, quantity, receiving slot or mounting position and every connected terminal, cable or carrier assembly.
Record revision restrictions, configuration or calibration dependencies, testing requirements and required certificates so the quoted extension cable matches the maintenance scope.
Confirm the current OEM lifecycle stage for 21747-040-00 against manufacturer records at quotation. The supplied extension cable is matched by its complete hardware identity, revision and included assemblies.
Any alternative is proposed only after the receiving Bently Nevada proximity measurement system, interfaces, configuration dependencies and commissioning requirements have been reviewed.
