Cross-reference check

Relationships and limits.

  • ASH664-5 and 100-1600-01 are printed as alternate spares for each other in the same item stack.
  • The row references Service Bulletin B24-3278 and prints no direct replacement number for ASH664-5.
  • Quantity 2 covers the No. 1 and No. 2 main-inverter positions.
Important limit

The ASH664-5 row establishes an alternate-spare relationship with 100-1600-01. It does not make every later 100-series or 140-series inverter directly interchangeable with ASH664-5.
