BOOK# 091-12VHO-2 REV: 10-11-2002 INSTRUCTION MANUAL AUTO CHARGE 12VHO AUTOMATIC BATTERY CHARGER MODEL #091-12VHO-XX NOTE : This charger is designed for vehicles with a single battery system 3 YEAR WARRANTY KUSSMAUL ELECTRONICS CO., INC. 170 CHERRY AVE., WEST SAYVILLE, N.Y. 11796 TEL: in NY 631-567-0314 TOLL FREE: 800-346-0857 FAX: 631-567-5826 INTRODUCTION The Auto Charge 12VHO is Battery Charger is a compact completely automatic charger designed for installation on vehicles with a single battery system. Remote sensing permits long lines between the charger and the batteries by compensating for the voltage drop in the charging wires. An ammeter provides continuous indication of the charger output. Construction of the Auto Charge 12VHO is extremely rugged to withstand the shock and vibration normally encountered by vehicle mounted equipment. The unit operates completely automatically and stops charging the batteries when they are fully charged. There is no trickle charge and therefore no danger of overcharging and water boil-off. Any parasitic loads on the battery such as radio, lights, etc., are automatically supplied with current by the charger. INSTALLATION The Auto Charge 12VHO Automatic Battery Charger should be installed in an area with adequate ventilation. A power cord is supplied for connection to A.C.. 1. Mount the charger using the four holes provided for this. 2. Connect the wiring from the battery to the Output Terminal Strip. Strip the wire insulation approximately 3/8". 3. Double check all wiring before proceeding. 5. Wire the A.C. power. 6. Pilot light will light to show that the charger has power. INSTALLATION WIRING DIAGRAM IMPORTANT: Each lead wire shall not be greater than 20 feet for the charger to deliver the full 20 amp output. If wiring is to be longer, consult the factory for additional information. NOTE: The sense leads must be connected to the battery system as shown for the charger to operate. A simple check can be made as follows see example: WIRE SIZE CHART CONNECTION ITEM DEFINITION WIRE SIZE BATBAT+ BATTERY NEGATIVE BATTERY POSITIVE NEGATIVE CHARGING LEAD FOR BATTERIES POSITIVE CHARGING LEAD FOR BATTERY # 1 NEGATIVE VOLTAGE SENSE LEAD. DETECTS VOLTAGE POSITIVE VOLTAGE SENSE LEAD. DETECTS VOLTAGE 10 AWG 10 AWG 16 AWG 16 AWG SENSE NEGATIVE SENSE POSITIVE SENSE SENSE + EXAMPLE: Assuming a 24 VDC battery system, the positive sense lead must read approximately +24 VDC with respect to the negative sense lead at the charger. The battery "+" terminal must read approximately +24 VDC with respect to the battery "-" terminal at the charger. These measurements shall be made before the AC power to the charger is applied.
