IMPORTANT SAFETY INSTRUCTIONS
I. PERSONAL PRECAUTIONS:
1. Someone should be within range of your voice or close enough to come to your aid when you work near
a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye and clothing protection. Avoid touching your eyes while working near a battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If battery acid enters
the eye, immediately ood eye with cold running water for at least 10 minutes and get medical attention
immediately.
5. NEVER smoke or allow a spark or ame in the vicinity of the battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit
the battery or other electrical part and cause a re or an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery, when shorted, can produce a current sucient to weld a ring or the
like metal causing a severe burn.
8. Use the battery charger for charging gel-cell, AGM and ooded lead-acid batteries only. Do not use the
charger for charging dry-cell batteries that are commonly used with home applications. These batteries
may burst and cause injury to persons and damage to property.
9. WARNING – RISK OF EXPLOSIVE GASES: Working in the vicinity of a lead-acid battery is dangerous.
Batteries generate explosive gases during normal battery operation.
II. CHARGER PRECAUTIONS:
1. NEVER charge a frozen battery.
2. Make sure the cord is located so that it will not be stepped on, tripped over, or otherwise subjected to
damage or stress.
3. Do not operate the charger with a damaged cord or plug; replace them immediately.
4. Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged.
5. Do not disassemble the charger. Incorrect reassembly may result in a risk of electric shock and re.
6. To reduce the risk of electric shock, disconnect the charger from the AC source before attempting any
maintenance or cleaning.
7. LOCATION OF CHARGER: The charger should be mounted on a wall, vehicle oor, ventilated compartment or other suitable surface as close to the batteries to be charged as possible. Do not block the charger’s fan or air intakes. Do not mount the charger directly over the batteries as fumes may cause exces-
sive corrosion. The area should be well ventilated and free from excessive moisture, exhaust manifolds,
and battery fumes. For maximum performance, the charger should not be located in an area of extreme
high temperature. The charger is not waterproof. Do not mount the charger where there is a possibility of
water entering the unit. Evidence of water entry into the charger will void the warranty.
8. CAUTION: Do not attempt to increase battery bank capacity by splitting the output of one of the banks
with a diode-type battery isolator. The diode isolator lowers the charger voltage and results in undercharging the batteries connected to it. If additional capacity is required it is preferable to add another
isolated or parallel battery.
III. GROUND AND AC POWER CORD CONNECTION:
1. The charger should be grounded via the AC power connection to reduce the risk of electrical shock.
2. The charger must be plugged into or wired to an outlet that is an over-current protected 3 prong outlet.
Alternatively, it may be routed through a separate dedicated fuse or circuit breaker on an AC distribution
panel with proper earth/safety ground. All wiring shall comply with UL recommendations, NEC or NFPA
standards and local ordinances. Never alter the AC cord or plug if provided. Any modication of the cord
must only be done by a qualied electrician. Improper cord/outlet connection may result in a risk of elec-
trical shock.
3. Observe color coding of the AC wiring as follows:
Black………....................... AC Hot or LINE (fused)
White…………................... AC Neutral
Green…….................…….. AC Ground (safety/earth)
4. CAUTION: (230 VAC applications only): If AC input is provide from a source consisting of two HOT or
LINE leads (phase-to-phase 230 VAC input voltage); an external fuse or circuit breaker must be used to
protect both hot leads.

INTRODUCTION
The New and Improved Auto Charge 4000, LPC, is a low prole, microprocessor controlled, completely
automatic, dual channel battery charger designed for vehicles with a dual battery system. This latest
generation of LPC charger improves upon user selectable functions, which includes user selectable
battery type. The LPC charger is also designed to withstand the shock and vibration encountered by
vehicle mounted equipment.
• Accommodates Lead-Acid, Gelled Electrolyte, AGM and Odyssey® battery types
• Power “ON” LED indicator
• System Status indicator
• Internal cooling fan
II. CHARGE CONTROLS & ELECTRONIC REMOTE SENSING
The AC 4000, LPC, contains a precision voltage controller to maintain the battery’s charge. The
output terminal is voltage regulated, and internal circuitry provides for constant power during loaded
situations. 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-o.
III. AUTOMATIC CURRENT LIMITING
When batteries are severely discharged, some battery chargers can be overloaded due to the high
charging current required. The AC 4000,LPC, contains an automatic current limit. The current limit
feature limits the output current 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
IV. BATTERY SELECTOR SWITCH (LEAD-ACID, GEL-CELL, AGM, or ODYSSEY®
DIP switches are used to select between various battery chemistries.

V. AUX OUTPUT
The output terminal strip provides an additional output to accommodate 12 volt accessories, such
as Kussmaul’s 12 VDC air pump. The AUX output works in conjunction with a front panel mounted
DIP switch. For normal operation, the DIP 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. If AC power is o, the aux ouput
operates from the vehicle’s batteries.
VI. LED STATUS INDICATORS
a. POWER: Green LED, indicates AC power is present.
b. SYSTEM: See specications page for description of system status.
VII. COOLING FAN
The AC 4000,LPC is fan cooled and automatically cycles on and o depending on output current.
When the fan is on, air is circulated and exhausted through the right side. The fan cycles briey when
power is applied in order to verify that it is functioning.
OPERATION
I. BATTERY TYPE SELECTION SWITCHES
Switches “1” and “2” should be used to match the battery chemistry. Units are shipped with all switched
down (default setting). Switches can be set at follows:
Lead-Acid - Both switches down (o) - factory default setting
Gelled Electrolyte (Gel-Cell) - Switch “1” down (o) and Switch “2” up (on)
AGM - Switch “1” up (on) and Switch “2” down (o)
Odyssey® - Both switches up (on)
NOTE: See specications for battery selector switch absorption and oat voltage
settings.

II. AUX OUTPUT
Switch “5” controls the Aux output operating mode.
AC – Switch “5” down (o) - factory default setting.
DC – Switch “5” up (on).
In AC mode, the Aux accessories will operate only when AC power is applied to the battery charger.
In DC mode, the Aux accessories will operate when the AC power is on or o. The Aux accessory
is powered by the charger while AC power is applied to the charger and from the vehicle’s battery
when no AC power is applied.
III. REMOTE BATTERY CHARGE CONDITION INDICATOR (Standard equipment)
This remote indicator shows the charge condition of the battery in 10 levels from “LOW CHARGE”
to “FULLY CHARGED”. This device indicates a defective battery when the bar graph does not rise
to the “FULLY CHARGED” level after an extended period of charging.
NOTE: If a battery is being charged with an external load of 1.5 to 4 amperes across its terminals,
the bar graph may move down 1 or 2 levels. This does not indicate a defective battery. To avoid this,
either reduce constant load draws or consider an external Battery Saver. Please contact Kussmaul
Electronics for further details.
