BOOK# 091-12-1 INSTRUCTION MANUAL AUTO CHARGE 12 DV AUTOMATIC BATTERY CHARGER MODEL #091-12DV-12 NOTE : This charger is designed for vehicles with single batteries either negative or positive ground INPUT : 115/230 volt, 50/60 Hz 3 YEAR WARRANTY KUSSMAUL ELECTRONICS CO., INC. 170 CHERRY AVE., WEST SAYVILLE, N.Y. 11796-1221 TEL: in NY 631-567-0314 TOLL FREE: 800-346-0857 FAX: 631-567-5826 INTRODUCTION This manual describes the installation and wiring for the Auto-Charge 12DV Automatic Battery Charger. It is suggested that the installer read The entire instructions to become familiar with the tasks involved before starting. INSTALLATION The installation of the vehicle wiring provides a direct connection between the battery and the Auto-Charge 12DV Automatic Battery Charger. The battery is automatically charged at constant voltage. For deeply discharged batteries or if the charger is operated while the vehicle is started, a current limiter automatically limits the output to 12 amperes. Input power may be either 115 volts or 230 volts, 50 or 60 Hz. A recessed voltage selector switch is provided on the end panel near the output terminal strip. The Auto-Charge 12DV uses remote sensing and therefore four wires are necessary to connect to the battery. Two wires charge the battery while an additional two wires detect the battery voltage. These connections are made on the output terminal strip. The Auto-charge 12DV Automatic Battery Charger should be installed in an area with adequate ventilation. A power cord is supplied for connection to the input power source. A switch on the end panel of the charger selects either 115 volts or 230 volts. Set this switch to the proper position to correspond to the input voltage before applying power to the charger. 1. Mount the charger using the four holes provided. See figure 1. 2. Connect the wiring from the batteries to the Output Terminal Strip. Spade lugs that have been securely crimped or soldered should be used 3. Connect the wiring to the batteries. Ring lugs that have been securely crimped or soldered should be used. 4. Double check all wiring before proceeding. 5. Wire the A.C. power line to the power source and check the position of the Voltage Selector Switch. 6. The pilot light will light to show that the charger has power. 7. The ammeter will indicate how much current is flowing to the battery. A charging current limit of 12 amperes is factory set. *************NOTE ************* DO NOT APPLY 230 VOLTS TO THE CHARGER WITH SELECTOR SWITCH IN THE 115 VOLT POSITION SERJOUS DAMAGE MAY RESULT INSTALLATION WIRING DIAGRAM 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.
