ABB 3HAC058366-001 / 3HAC058399-003 identify two related IRC5 panel-mounted controller records: the 3HAC058366-001 computer unit and the 3HAC058399-003 system-power record. Together they describe the controller electronics and its associated power path, not one interchangeable article.
The computer record in ABB 3HAC058366-001 / 3HAC058399-003 is associated with the IRC5 panel-mounted cabinet, while the power record remains tied to the controller supply arrangement. The two ordering numbers stay separate so the computer, supply and cabinet wiring are not collapsed into one generic spare.
When servicing ABB 3HAC058366-001 / 3HAC058399-003, the panel is isolated first, the computer and power connectors are documented independently, and the controller software/startup state is checked only after both records have been reconciled.
