3.0 Installation and safety
The HV Power Supply must be mounted indoors, protected from weather
Elements, in a location easily accessible by operating service personnel.
The HV Power Supply is equipped with universal input; power factor corrected (PFC)
AC/DC power supply and can operate from 120VAC or 240VAC power lines.
The maximum current draw is 0.85 Amp from 120 VAC line and 0.42 Amp from 240VAC
line. Use these numbers to select proper wire gage as per applicable standards.
The connection diagram of HV Power Supply is shown in Fig.2 All connections are
made to terminals on the Main Board.
The HV Multiplier has two outputs:
Ionizing Voltage –Labeled as 14kVDC
Collector Voltage –Labeled as 7kVDC
The HV and current adjustment trim pots and status LEDs are located at the edge of
the Main Board as well as AC power input , HV Good Relay and RS-485 serial port.
4.0 Field wiring connections
These instructions are for qualified personnel only. To reduce the risk of electric
shock, do not perform any servicing other than contained in the instructions
unless you are qualified to do so. All wiring must be installed according to
national, state and local codes.
The HV Power Supply requires the following field connections:
1. AC line connection including safety GND (J10, highlighted in green)
2. HV Connection (7kV and 14kV terminal studs, highlighted in red)
3. HV Good Relay contacts (J1, highlighted in green)
4. RS-485 / Modbus communication port (J12, highlighted in green)
5. HV GND and AC GND (corner mounting screws to carrier plate)
