Basic Component Removal Procedures
6. If present, remove all customer wiring to Transitional Busbar assembly.
7. Remove the DC Choke output cables.
8. Disconnect the DC+ and DC– cables from the Transitional Busbar
assembly.
9. Remove all IGBT Snubber components (3 sets):
a. Remove the six Snubber Capacitor mount nuts. Remove capacitors, and
save the nuts and capacitors.
b. Remove the two screws that secure each Tie Down Capacitor Mount.
Remove the Tie Down Capacitor Mounts and save screws and
Capacitor Mounts.
c. Remove the six set screws from each IGBT and save.
