Verify the complete ABB product ID 64425579A before replacement.
Confirm that the installed board is an NINT-73C main circuit interface.
Record all existing cable and connector positions before removing the original board.
Isolate the drive from all power sources before servicing the main circuit hardware.
Inspect mating connectors and wiring before installing the replacement.
Confirm the associated ABB drive configuration before energizing the system.
Check drive status and fault indications after replacement.
Match both 64425579A and NINT-73C when sourcing a replacement.
Do not select another NINT board solely by visual similarity.
Confirm the exact drive hardware and cabinet configuration before substitution.
