HV Charger
The HV Charger is fitted in the middle of the chassis and runs from the rear to the front of the unit.
The charger is designed as a module, and we would not expect that field servicing could be carried
out on this unit.
Connections:- L2 - LINE
COM – NEUTRAL
GROUND
AC Section
The AC Section is to the left of the charger. Access to it can be gained by firstly removing the top
plate and by lowering the left hand side panel.
Once the LH panel has been removed you will see (from back to front) the AC mains filter, a 90-
250VAC 12VDC power supply, 2 control relays and a separate 12 V power supply for these relays.
Input fuses can be found on the rear panel :-
Protects 12v power supply
Protects the relay board and line voltage powering the high voltage relays, also the front panel
fans.
Control Board and Front Panel Components
The control board is mounted on left hand side panel.
Descriptions of the control board and the front panel items - such as power selector switch and
display board are detailed later in this section.
The Troubleshooting Guide can be used to assist the operator in identifying any malfunction.
