section to identify any components discussed in this section.

IMPORTANT

Each IGBT replacement kit includes three positive (DC+) and three negative
(DC-) Flexible Capacitor Busbars. The positive Flexible Capacitor Busbars are
shorter (see above) because they attach to the back side of the Transitional
Busbar assembly. For ease of installation, replace positive Flexible Capacitor
Busbars while the Transitional Busbar assembly is removed.
