General\nThe HV Power Supply (HVPS) must be mounted indoors, protected from weather elements, in a location\neasily accessible by operating service personnel to enable inspection and clean up.\nThe HVPS board is conformal coated however accumulation of dust and lint may result in HV current\nleaks and degraded performance especially in high humidity conditions.\nPlease insure that the HCV power supply compartment is well ventilated by fan to insure air circulation.\n\nThe board must be mounted at least ½” above conductive surface to prevent arcing.\nInsulating pad of the size of the board is highly recommended to be installed below the board.\n\nThe HVPS board is factory adjusted to 8kV. The adjustment range is 7.2 kV to 8.5kV. If necessary the\nHV can be adjusted by trim pot RV1 (labeled HV Adjust). The output current is limited to 1mA. The HV\nsupply output power is limited to ~ 10W. The HVPS board maintains output regulation at no load\ncondition however we do not recommend prolonged operation at no load.\n\nThe HVPS is equipped with universal input, AC/DC power supply and can operate from 120VAC or\n220VAC 50/60HZ power lines.\nThe maximum current draw is 0.2 Amp from 120 VAC line and 0.1 Amp from 220VAC line.\nUse these numbers to select proper wire gage as per applicable standards.\n\nThe HVPS can be also operated from 24 VDC power supply. Consult factory if 24VDC version only (no\nAC power) is preferred.\n\n\n\n\n 2. Field wiring connections\n\nWARNING - RISK OF ELECTRIC SHOCK\n\n\n\n\n 1\n\f These instructions are for qualified personnel only. To reduce the risk of electric shock, do not\nperform any servicing other than contained in the instructions unless you are qualified to do so. All\nwiring must be installed according to national, state and local codes.\n\n\n\n\nFig.2 HV supply connecting points\n\n\nThe HVPS has the following field connections available:\n\n 1. AC power input (quick disconnect terminals)\n 2. 24V DC power input (optional, contact factory))\n 3. HV Connection (+8kV and +4kV quick disconnect terminals)\n 4. HV Status dry contacts\n 5. Bicolor LED indicating HV output status\n\nConnecting points are shown in red in Fig.1 and recommended connections to load cell are shown in\nFig.2.\n\nAC line connections\n\nThe HV power supply requires Live, Neutral and GND connection for safe operation.\n\n 2\n\fConnect Live wire (black) to ”L” terminal and Neutral wire (white) to “N” terminal.\nConnect GND wire (green) to safety Earth GND screw on the chassis.\nConnect “Earth” terminal on the HV supply board to safety Earth GND screw on the chassis.\n\n\n HV Connections\n\nHigh voltage connection is made to quick disconnect terminals labelled +8kV and +4kV.\nConnect the ionizer cable to +8kV terminal and collector cable to +4kV terminal. The HV return current\ncloses through the HV GND terminal.\n\n\n\n HV\n LED GND\n COLLECTOR\n 24VDC\n HV Power Supply\n HV STATUS\n EARTH LOAD CELL\n +4kV\n GND\n AC N AC N\n IONIZER\n AC L AC L +8kV\n\n EARTH\n GND\n Chassis GND\n\n\n\n\nFig.2 Recommended connections to load cell\n\n\n 3. Power – up and verification\n\n 1. Connect bi color LED cable and dry contact cable.\n 2. Connect the load cell, turn power ON. The bicolor LED should turn ON green and dry contacts\n should stay open. Using well insulated HV cable short briefly 8kV to GND and verify that bicolor\n LED turns red and dry contact closes.\n\n\n\n\n 3.
