Ensure that the Generator Supply Command Board Capacitors are Discharged
1. Wait 10 minutes for the components within the Generator to discharge.
2. Switch off the electrical power supply on the rotary switch in the Generator cabinet (position 0).
3. Using a voltmeter (rating 1000 V DC), check that there is no residual voltage between screws S1 and
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
