Ensure that the Mains Distribution Board Capacitors are Discharged
1. Wait 10 minutes for the components within the Generator to discharge.
WARNING
It is important that you switch off the external power supply on the Mains Distribution
Panel. This is because you will be working in close proximity to where the external voltage
arrives into the Generator.
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 Mains Distribution board.
4. The XJ8 and XJ9 connectors may still have a residual voltage of 600V DC from the C1, C2, C5, C6,
C7, and C8 capacitors located behind the Mains Distribution board. Using a voltmeter (rating 1000 V
DC), check that there is no residual voltage (600V DC) between the XJ8 and XJ9 connectors connec-
