Chapter 3 Component Replacement Procedures 5. Remove the Gate Interface board. See page 53. Current Transducer Assembly Tie Down Capacitor Mount Output Busbar Snubber Capacitors IGBT Gate Interface Board Assembly (not shown above) AC Output Busbar 6. Carefully examine the transitional busbar and bus capacitors for damage. When replacing any IGBT, Rockwell Automation recommends that you replace all bus capacitors. If needed, refer to Bus Capacitor on page 45 to replace damaged bus capacitors. Example of IGBT Module Failure Bus Capacitor, under Transitional Busbar Transitional Busbar Flexible Capacitor Busbars 7. Remove the eight screws that secure the IGBT to the chassis. 8. Remove the IGBT by tipping the right edge out first. 50 Rockwell Automation Publication 20B-IN024C-EN-P - June 2012
