3. That wire size is large enough for ac ampere rating of charger.
Do not operate charger with damaged cord or plug-replace the cord or plug immediately.
Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in
any way;contact Charging Systems International.
Do not disassemble charger; contact the factory when service or repair is required. Incorrect
reassembly may result in risk of electrical shock or fire.
To reduce risk of electric shock, unplug charger from outlet before attempting any
maintenance or cleaning.
WARNING-RISK OF EXPLOSIVE GASES.
1. WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS.
Batteries generate explosive gases during normal battery operation. For this
reason, it is of utmost importance that each time before using your charger, you
read this manual and follow the instructions exactly.
2. To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicin-
ity of battery. Review cautionary marking on these products and on engine.
PERSONAL PRECAUTIONS
Someone should be within range of your voice or close enough to come to your aid when you
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near
battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flood eye with running cold water for at least 10 minutes and get
medical attention immediately.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or
short-circuit battery or other electrical part that may cause explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working
with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to
weld a ring or the like to metal, causing a severe burn.
Use charger for charging a LEAD-ACID (lead acid, sealed lead acid, gel cell and AGM) battery
only. It is not intended to supply power to a low voltage electrical system other than in a
starter-motor application. Do not use battery charger for charging dry-cell batteries that are
commonly used with home appliances. These batteries may burst and cause injury to persons
and damage to property.
CAUTION: DO NOT ATTEMPTTO INSTALL THE XTREME IN A BATTERY CONFIGURA-
TION THAT UTILIZES A SERIES CONNECTION FROM THE CRANKING BATTERY TO ONE
OF THE TROLLING MOTOR BATTERIES. SEVERE SPARKING AND/OR DAMAGETO THE
PROXTRA CIRCUITRY MAY OCCUR AND THE WARRANTY WILL BE VOIDED.
PREPARING TO CHARGE
3

4
If it is necessary to remove the battery to charge, always remove grounded terminal from
battery first. Make sure all accessories are off, so as not to cause an arc.
Be sure area around battery is well ventilated while batteries are being charged. Gas fumes
can be forcefully blown away by using a piece of cardboard or other nonmetallic material, as a
fan.
Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery
without cell caps, carefully follow manufacturer’s recharging instructions.
Study all battery manufacturers’ specific precautions such as removing or not removing cell
caps while charging and recommended rates of charge.
Extension cords should be industrial grade/heavy duty U.L. approved and grounded. Check
extension cord before use for damage, bent prongs and cuts. Replace if damaged.
Always make your extension cord connection on the charger side first. After connecting the
extension cord to the charger, then proceed to plug the extension cord to a nearby 120VAC
GFCI protected (Ground Fault Circuit Interrupt) outlet.
Always remove the extension cord from the 120VAC outlet first when charging is completed
followed by unplugging the charger.
PRODUCT SUMMARY
General Operation:
Use the following guidelines in this manual to install your fully automatic Charging Systems
International battery charging system.
Assure that your charger and batteries are properly vented. Connect your extension cord with
no AC Power present to the battery charger and proceed to plug your extension cord in at a
nearby 120VAC GFCI protected (Ground Fault Circuit Interrupt) outlet.
Once you plug in your Charging Systems International battery charging system, your batteries
will be simultaneously and independently charged to 100%. Unlike systems that utilize one large
charger to attempt to charge multiple batteries, your system utilizes a totally independent battery
charger for each battery. Each charging bank will turn itself completely off once the battery is
charged and then monitor and maintain the battery indefinitely.
We recommend that you leave your system plugged in to reduce sulfate build-up and to allow
your Charging Systems International charging system to keep your batteries fully maintained
and ready to perform at their best.Your Xtreme Series system also utilizes specially designed
circuitry to enable independent charging current to flow to additional batteries. This system is
enabled and operates automatically whenever the engine starting battery is being charged
and maintained by the engine driven charging system.
Independent Charging Bank Indications
When your battery charging system is activated , each bank provides charging information
utilizing five red LED indicators and one green LED indicator. These indications occur only
when the charger is being powered by AC.
The five red LEDs enable you to track the progress of the charge cycle on each battery as the
voltage rises. Indications are as follows:

"Charging on the run" indications
During periods in which the engine starting battery is being charged and maintained by the
engine driven charging system, amber and red LED indicators are provided which display
the state of the integrated "ProXtra" circuitry that controls the flow of current to additional
batteries.
Indications are as follows:
CHARGING CRANKING BATTERY-This amber LED is illuminated whenever the voltage of
the engine starting battery is in excess of 13.0 Volts.
CHARGING ADDITIONAL BATTERIES-This red LED is illuminated during periods when
the "ProXtra" circuitry is allowing charging current to flow to additional batteries.
INSTALLATION INSTRUCTIONS
All Charging Systems International battery charging systems are designed to be perma-
nently mounted and have no mounting restrictions.
Do not make any electrical connections to the power supply (AC) or to a battery (DC) until
the mounting process has been completed.
Check for fit and appropriate thickness of mounting area. It is recommended that you choose
a flat surface. If a compartment wall is chosen, make certain its strength is adequate.
Use the mounting flanges of the charger to mark locations for starter holes. Drill a 1/16"
inch hole at each marked location. Then, utilize all stainless steel screws which have been
provided and install the charger securely being cautious not to over tighten the screws.
Silicon sealer should be used to secure and waterpoof the screw holes.

Before making any connections, prepare batteries as follows:
(a) With caps securely in place, thoroughly clean the case and posts with a solution of
baking soda and water. Be careful not to allow any soda to get inside the case.
(b) All posts, terminal and connections should be cleaned to a shiny bright finish, using
a wire brush or sand paper. This should be done periodically to assure maximum
conductivity.
Charge Cables #1 and #2
Each charge cable assembly is equipped with a temperature sensor located at the junction
of each set of ring terminals. Attempts to lengthen or shorten the cables could partially dis-
able the charger. Therefore, we recommend that you do not make any adjustments without
first consulting the factory.
Route your cables from the charger to your batteries, being cautious to avoid sharp
objects and use the supplied wire ties to hold them neatly in place. Securely connect the
red (+) charger ring terminals to the positive battery posts and the black (-) charger ring
terminals to the negative posts. If the unit is equipped with a standard AC plug on the
power cord, a plug receptacle is also provided to hold the power cord plug when it is not
being used. Locate a convenient site for the receptacle and attach it using the four
smaller stainless steel screws.
Cranking Battery Cable
The cable assembly designated for the engine starting battery is unique in that in addition
to the Red (+) and Black (-) wires, there is a purple wire which must be attached to a 12
volt source that is switched on and off by the engine ignition key switch. Use the supplied
quick connector to attach the purple wire to any key activated 12 volt source. It is important
to note that the "charge on the run" circuitry will not operate unless the purple wire is connected
to a 12 volt source.
TROUBLE SHOOTING
PROBLEM: No LED indicators illuminate in any of the charger banks.
Solution Sequence:
Check the AC power supply from its source through all connecting points up to the charger
by using a meter or test light to confirm that current is being delivered to the charger.
PROBLEM: One red LED flashing.

Solution Sequence:
With the AC power supply cord unplugged, check the ring terminals for correct
polarity (Red to positive or +) and (Black to negative or -). Also check for corrosion free
secure connections to the batteries. Call the factory for further assistance.
PROBLEM: The LED indications change rapidly back and forth from red to green or
the green LED will not illuminate after excessive charging time (16 hours or more).
Solution Sequence:
Disconnect AC power to the charging system. On multi bank chargers, take the charge
cable assembly from the affected bank off of the battery it is attached to and attach it to
another battery in the boat. Take the original charge cable assembly from this battery and
attach it to the battery from which you removed the first cable. Plug the charger in and
observe the LED indications. If the rapid LED sequence (red to green repeatedly) occurs
on a different bank of the charger, this confirms that there is a battery problem.
On single bank systems, simply try the charger on another battery. If the charger now
operates normally (steady red LEDs or changes to green and holds), this signifies that
there is a possible problem with the original battery.
If the same bank continues to malfunction, please call the factory.
PROBLEM: A green LED was illuminated before disconnecting the power from the
charger, but upon reconnection, red LEDs appear and remain on.
This is normal operating procedure for the system and simply indicates that a re-analysis of
the battery status has been initiated and after a series of steps,the green LED will illumi-
nate.
PROBLEM: The indicator lights from the ProXtraII "charge on the run" system are
not illuminating while the main boat engine is running.
Solution Sequence:
Check that each charge cable ring terminal is attached securely and with proper polarity.
Check that the purple 12 volt sense wire from the cranking battery cable assembly is
installed properly.
Check engine RPMs. The system may not operate with the engine at idle. Assure that the
system has been tested at higher engine RPMs.
For further troubleshooting, please contact the factory at 1-800-742-2740.
PROBLEM: One or both indicator lights on the ProXtraII "charge on the run" system
remain on after the main engine is shut down.
Solution Sequence:
It is normal for the "charging additional batteries" and "charging cranking battery" lights to
remain on for a brief period of time following main engine shutdown. As the battery volt-
ages decrease, the lights will extinguish.
If one or both lights remain on indefinitely, please contact the factory at 1-800-742-2740.

POST INSTALLATION TESTING
After completing the total installation process for your Xtreme system, it is possible to test the
ProXtraIl section of the system for proper operation without having to operate the main engine.
Attach a battery charger designed for a 12 volt system to the cranking battery.
Turn the ignition key switch to the ON position.
Turn the charger on and observe the indicator lights on the ProXtraII section of the Xtreme.
When the voltage of the cranking battery reaches a factory predetermined level, the "charging
cranking battery" light will illuminate. As the voltage of the cranking battery continues to rise,
the "charging additional batteries" light will illuminate.
Once both indicator lights have illuminated, unplug the charger attached to the cranking bat-
tery. As the battery voltage drops to a factory predetermined level, both indicator lights should
extinguish.
If unable to accomplish the previous steps for any reason, please call Charging Systems
International at 1-800-742-2740 for further assistance.
