1. Board Connector J4 Aerial Connector a Resistor 8R1 HF Series Generators Installation illustration 2 6 Checking voltage Check that voltage on 8F3 and 8F4 is gt 10 VDC Check that the voltage stored in Capacitors is lt 10 VDC maximum voltage for a safe service manipulation It is recommended that voltage will be close to 0 VDC For that check that LEDs D48 and D49 are OFF and then measure the voltage at the base of Fuses 8F3 and 8F4 DO NOT MANIPULATE INSIDE THE UNIT WITHOUT CHECKING THAT VOLTAGE IN CAPACITORS MODULE HAS BEEN DISCHARGED LESS THAN 10 VDC Note Storage Capacitors are fully charged four seconds after turning the Generator ON for a line of 230 VAC with selection of 20 A in the Generator or maximum 40 seconds for a line of 110 VAC with selection of 8 A in the Generator 102. PRESENT IN THE UNIT EVEN IF IT IS UNPLUGGED FROM THE AC LINE NEVER TOUCH METAL PARTS UNDER COVERS BEFORE TESTING THAT VOLTAGE IS BELOW 10 VDC PERFORM THE PROCEDURE FOR CAPACITORS DISCHARGING AND VOLTAGE TESTING PREVIOUS TO MANIPULATE INSIDE THE GENERATOR FOR SERVICE KEEP IN MIND THE GENERAL CAUTIONS FOR CAPACITOR ASSISTED GENERATORS INDICATED BEFORE With the Generator turned OFF be sure that the Power Supply Cable is unplugged from the Mains socket Take away the Generator cover Carefully remove the Protection Cover over the Capacitor Charger Board A3517 xx DO NOT TOUCH ANY METAL PART UNDER COVERS UNTIL THE CAPACITORS ARE FULLY DISCHARGED AFTER THIS PROCEDURE HF Series Generators Illustration 2 5 Installation Resistor 8R1 1K5 ohms 250 W is assembles close to the Capacitor Charger Board to allow the Capacitors discharging Connector J4 from this resistor must be disconnected for normal operation of the Unit and ONLY MUST BE CONNECTED to the J4 of the Capactitor Charger Board for Capacitors discharging process Plug Connector J4 in the Capacitor Charging Board Check that LEDs D48 and D49 of this Board are blinking When the Capacitors are fully discharged both LEDs will be OFF Capacitors will be discharged from 800 VDC fully charged to 10 VDC in approximately 5 minutes Connection of J4 for Capacitor Discharging LEDs D48 amp D49 Connector J4 PCB Connector Capacitors Charging
