Replacement
1. Turn the Workstation off and remove its power plug from the AC outlet.
2. Remove the C-Arm's Rear Cover and disconnect the steering linkage.
3. USING GREAT CARE TO AVOID ELECTRIC SHOCK, disconnect battery cables from P1A and P3B on Capacitor/Power
module. (Refer to Capacitor/Power module replacement procedure in this chapter for more details.)
4. Locate two battery cables just above P1A and P3B. These two cables have blue connectors that connect to each other.
USING GREAT CARE TO AVOID ELECTRIC SHOCK, disconnect battery cables from each other. (Refer to
Capacitor/Power module replacement procedure in this chapter for more details.)
5. USING GREAT CARE TO AVOID ELECTRIC SHOCK, connect a current-limiting resistor (300k or so) across
Capacitor/Power module busbars to discharge high energy capacitors inside Capacitor/Power module. (Refer to
Capacitor/Power module replacement procedure in the chapter for more details.)
3. Turn OFF CB1 on the bottom of the Capacitor/Power Module.
4. Remove the seven screws that secure the Generator Driver Cover and remove the cover.
5. Remove the Filament Driver PCB to gain access to the IGBT Snubber PCB.
6. Remove the screws that secure the wire terminals to the IGBT PCB.
7. Remove two recessed hex bolts from the IGBT PCB
8. Remove two screws from the edge of the IGBT PCB.
9. Remove the IGBT PCB and integrated heat sink.
