The power card may remain attached to the power card
mounting plate, if the power card mounting plate is to be
removed.
1. Remove the control assembly support bracket in
accordance with the procedure.
2. Unplug power card connectors MK102, MK103,
MK105, MK106, MK107 MK109, and both MK112
connectors.
3. Remove the 7 mounting screws (T-25) from the
power card.
4. Remove the power card from the plastic standoff
at the top right of the power card.
5. Remove the current scaling card from the power
card by pushing in the retaining clips on the
