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 instruction manual to become familiar
with the tasks involved before operating the charger.
INSTALLATION
The installation of the vehicle wiring must provide a direct connection between the battery [+,
-] terminals and the Auto-Charge 12DV, Model: 091-165-12-DV, 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 VAC or 230 VAC, 50 or 60 Hz. A
recessed input voltage selector switch is provided on the charger front panel near the input
terminal strip.
The Auto-Charge 12DV uses remote sensing via the charging wires to the battery under
charge and therefore only the battery charging wires are necessary to connect to the battery
to the charger. These connections are made on the "OUTPUT" terminal strip.
Refer to FIGURE 1, Installation Wiring Diagram.
The Auto-Charge 12DV Automatic Battery Charger should be installed in an area with
adequate ventilation. A switch on the front panel of the charger selects either "115V" or "230V"
VAC. 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. Refer to "OUTLINE DRAWING,
FIGURE 2.
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 VAC input 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.
*************IMPORTANT SAFETY INSTRUCTIONS*************
DO NOT APPLY 230 VOLTS TO THE CHARGER WITH
115/230VAC SELECTOR SWITCH IN THE 115 VOLT POSITION
SERIOUS DAMAGE WILL RESULT
