INTRODUCTION
The Auto Charge 11HO-PIM Battery Charger is a compact completely automatic charger
designed for installation on vehicles with two batteries. An internal charge divider charges
both batteries simultaneously while maintaining battery isolation. 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 11HO-PIM is extremely rugged to withstand the shock and
vibration normally encountered by vehicle mounted equipment. The unit operates com-
pletely 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.
Any 120 volt loads when plugged into the GFI on the Auto-Charge 11HO-PIM will be
protected from ground faults. A separate lever operated circuit breaker protects the GFI
connected loads. This circuit breaker may also be use to disconnect these loads from the
line. The fuse on the Auto-Charge 11HO-PIM protects the charger only.
INSTALLATION
The Auto Charge 11HO-PIM Automatic Battery Charger should be installed in an area with
adequate ventilation. A power cord is supplied for connection to 115 volts 60 Hz.
1. Mount the charger using the four holes provided for this.
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. Double check all wiring before proceeding.
4. Wire the A.C. power line cord to 115 volts.
5. Pilot light will light to show that the charger has power.
