IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS - This manual contains important safety and operating
instructions for battery charger model: 091-206-12.
2. Do not expose the charger to rain or snow.
3. Wire charger inaccordance with all: National, Local and/or Underwriter requirements
for NEMA.
4. Do not operate the charger if it has been dropped or otherwise damaged in any way;
take it to a qualied serviceman.
5. Do not disassemble charger; take it to a qualied serviceman when service or repair is
required. Incorrect reassembly may result in a risk of electric shock or re.
6. To reduce risk of electric shock, disconnect AC input power before attempting
installation, maintenance or cleaning.
CAUTION:
CHARGING LEADS MUST BE DISCONNECTED FROM
BATTERY PRIOR TO WORKING ON CHARGER
7. DC CONNECTION PRECAUTIONS:
a) When connecting DC output wires to the charger always connect to the
charger rst and then to the battery.
b) When disconnecting DC output wires to the charger always disconnect
wires at the battery rst and then disconnect wires at the charger.
8. Charger Location:
a) Locate charger as close to batteries as possible, but not inside the battery
compartment.
b) Never place charger directly above battery or in battery compartment; gases from
battery will corrode and damage charger.
c) Do not operate charger in a closed-in area or restrict ventilation in any way.
e) Do not set a battery on top of charger.
9. Always install high current circuit breaker, supplied with each charger, in-line with the
charger DC output. The circuit breaker should be installed closest to the battery terminal.
10. Always install battery terminal insulators, supplied with each charger, at the charger
DC output terminals.

INTRODUCTION
The AUTO CHARGE LPC SERIES is a low prole, completely automatic, single channel,
battery oat charger designed for vehicles with a single battery system. The LPC improves
upon package size and parasitic systems. The charger is also ruggedized to withstand
the shock and vibration encountered by vehicle mounted equipment.
FEATURES
• Charger controller
• Automatic current limiting
• Remote voltage sense
• Remote charger indicator display
• LED status indicators
• AUX output with AC or DC mode rocker switch and automatic fuse protection
• AC input circuit breaker protection
• Fan cooled
• Reverse polarity protected by external inline fuse
FUNCTIONALITY
Charger Controller:
The Auto Charge LPC contains a precision voltage controller to regulate the output voltage.
Using high-frequency switching technology the output terminal voltage is compared to
a reference voltage, any error detected is then used to control the charger output at the
desired level. There is no “trickle charge” and therefore no danger of overcharging and
water boil-off.
Automatic Current Limiting:
When batteries are severely discharged, some battery chargers can be overloaded due to
the high charging current required. The Auto Charge LPC contains an automatic current
limit circuit. The current limit feature limits the output current to 80 amperes when charging
a deeply discharged battery, or if the starter cranks the engine while charging. The current
limiter thus eliminates the need for an ignition interlock circuit.
Remote Battery Sense:
Adding sense leads from the charger to the battery compensates for voltage drop in the
charging wires. The charger automatically compensates for this voltage drop and boosts
the charger output voltage in order to maintain the voltage at the battery constant.

Remote Charger Indicator Display:
The standard indicator displays the charge condition of the battery in 10-levels from “LOW
CHARGE” to “FULLY CHARGED”. This device indicates a defective battery when a bar
graph does not rise to the “FULLY CHARGED” level after an extended period of charging.
See option accessories for enhanced charger indicator displays. Note: If a battery is being
charged with an external load of 4 to 10 amperes across its terminals, the bar graph may
move down 1 or 2 levels. This does not indicate a defective battery.
LED Status Indicators:
• BATTERY OK: Indicates that a battery of proper polarity is connected to the charger
output terminals.
• AUX ON: Indicates that power to the AUX output terminal is ON.
• AC ON: Indicates that AC input voltage is present. Note: Battery must be above
9VDC and of proper polarity.
AUX Output:
The output terminal strip provides an additional output to accomodate 12 volt accessories,
such as: Kussmaul's 12VDC air pump. The AUX output works in conjunction with a front
panel mounted rocker switch. For normal operation, the rocker switch should be left in AC
mode, which means that the aux accessory works only when shoreline power is supplied
to the charger. With the switch in DC mode the aux accessory will operate when AC power
is ON or OFF. In either position the aux output operates from the vehicle's batteries, while
the charger automatically recharges the batteries as required.
AUX Output Automatic Reset Fuse:
The LPC contains an internal automatic reset fuse. Should the AUX output fuse open,
reset the fuse by cycling the AC input power (shore line). Note: the AUX rocker switch
must be in AC mode.
AC Input Circuit Breaker Protection:
The charger AC input is circuit protected with a panel mounted manual reset circuit breaker.
Cooling Fan:
The LPC is fan cooled and turns on when the charger is on. Air is circulated from the rear
panel and exhusted through the front panel.
Reverse Polarity Protected (only when externally fused):
A surface mounted high current manual reset circuit breaker is provided with each charger.
The circuit breaker must be installed with every charger to provide reverse polarity protection.
If the circuit breaker is not installed then the charger will not be reverse polarity protected.

OPERATION
Battery Charger Output:
1. A discharged battery is recharged to roughly 90% or until the current tapers down
to less than 2 amps. The ouput voltage never exceeds the oat voltage, which is
regulated from 0 to 80 amps (current-limit).
2. The charger will continue to charge the battery until the voltage at the battery reaches
oat voltage level.
AUX Output:
1. The AUX output is current-limited to 15 amps via an internal automatic reset fuse.
The AUX output shares current demand with the battery output. The combination
of both outputs never exceeds 80 amps. If the AUX output demands 15 amps then
the battery output will be limited to 65 amps.
2. The AUX output voltage follows the battery output voltage.

WIRING
1. Refer to Installation Wiring Diagram.
2. CAUTION: CONNECT DC WIRES TO CHARGER FIRST, THEN TO BATTERIES.
2. Terminate #2AWG or larger cable wire using 5/16" ring lugs, included in hardware
pack. Torque rating 15ft-lb max.
3. Install 100 amp circuit breaker using 5/16 ring lugs in line with BAT (+), included
in hardware pack. Note: Circuit breaker should be placed closest to battery
terminal. Torque rating 50in-lb max.
4. Double check all wiring before applying 240 AC volts to input terminal. Verify that
the battery voltage appears at the charger output terminals. Note: A minimum of
9 volts is required to start the charger.
5. Apply 240 VAC (shoreline power) to input terminal and observe that the charger
is operating. The Remote Bar Graph need not be connected for the charger to
operate.
