DSSA165 is a ABB power supply 6a used within the ABB Advant distributed control system. It provides the specified power supply 6a function while retaining the complete order code, hardware execution and receiving-system compatibility during replacement. Its documented series is ABB Master.
Power Input: DSSA165 performs the power supply 6a function within the ABB Advant OCS. The retained documentation identifies series as ABB Master; 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.
Integration Review: approve DSSA165 only for the documented ABB Advant distributed control 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.
Loop Testing: isolate the equipment, remove stored energy and inspect the receiving hardware before installing DSSA165.
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 DSSA165 and that its power supply 6a form, faceplate, connectors and printed revision agree with the approved ABB Advant OCS receiving record.
Retained product evidence for this execution includes Series: ABB Master. Use photographs of the label and installed position to resolve ambiguity before shipment or installation.
For DSSA165, provide the installed ABB Advant distributed control 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 power supply 6a matches the maintenance scope.
Confirm the current OEM lifecycle stage for DSSA165 against manufacturer records at quotation. The supplied power supply 6a is matched by its complete hardware identity, revision and included assemblies.
Any alternative is proposed only after the receiving ABB Advant distributed control system, interfaces, configuration dependencies and commissioning requirements have been reviewed.
