S2 before proceeding.
WARNING
Residual voltage stored in the resonant capacitors can be dangerous. Ensure that the res-
onant capacitors are fully discharged before you handle the Generator Supply Command
board.
4. The XJ6 and XJ7 connectors may still have a residual voltage of 35V DC from the C2 capacitor
located behind the Generator Supply Command board. Using a voltmeter (rating 1000 V DC), check
