IMPORTANT & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS — This manual contains important safety and
operating instructions for the battery charger.
ALL BATTERY CHARGERS
1. CAUTION — To reduce risk of injury, charge only lead acid or sealed gel cell type
rechargeable batteries. Other types of batteries may burst causing personal injury and
damage.
2. Do not expose battery charger to rain or snow.
3. Use of an attachment not recommended or sold by the battery charger manufacturer may
result in a risk of re, electric shock, or injury to persons.
4. Do not disassemble battery charger; take it to a qualied serviceman when service or
repair is required. Incorrect reassembly may result in a risk of electric shock or re.
5. To reduce risk of electric shock, disconnect battery charger from batteries and DC supply
before attempting any maintenance or cleaning. Turning off controls will not reduce this
risk.
6. WARNING — RISK OF EXPLOSIVE GASES.
a. WORKING IN 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 SERVICING
EQUIPMENT IN THE VICINITY OF THE BATTERY, YOU READ THIS MANUAL AND
FOLLOW THE INSTRUCTIONS EXACTLY.
b. 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 vicinity
of battery. Review cautionary marking on these products and on engine.
7. PERSONAL PRECAUTIONS
a. Someone should be within range of your voice or close enough to come to your aid
when you work near a lead-acid battery.
b. Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.
c. Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
d. If battery acid contacts skin or clothing, wash immediately with soap and water.
If acid enters eye, immediately ood eye with running cold water for at least 10
minutes and get medical attention immediately.
e. NEVER smoke or allow a spark or ame in vicinity of battery or engine.
f. 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.

4
g. 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.
h. NEVER charge a frozen battery.
i. If necessary to remove battery from service, always remove grounded terminal from
battery rst. Make sure all accessories are off, so as not to cause an arc.
j. Be sure area around battery is well ventilated.
k. Clean battery terminals. Be careful to keep corrosion from coming in contact with
eyes.
l. Study all battery manufacturer’s specic precautions such as removing or not
removing cell caps while charging and recommended rates of charge.
m. Add distilled water in each cell until battery acid reaches level specied by battery
manufacturer. This helps purge excessive gas from cells. Do not overll. For a battery
without cell caps, carefully follow manufacturer’s recharging instructions.
8. BATTERY CHARGER LOCATION
a. Never place battery charger directly above battery; gases from battery will corrode
and damage converter.
b. Never allow battery acid to drip on battery charger when reading gravity or lling
battery.
9. O/P CONNECTION PRECAUTIONS
a. Connect and disconnect DC output connections only after setting battery charger
switch to off position.

Installation
Allow at least 1 inch of clearance all around the case for cooling. The best mounting
conguration is to mount the unit on a vertical surface oriented as shown. Use #10 screws of
the appropriate type for the mounting surface to securely mount the unit.
There is 1500 volts (500V for 24V Input) of isolation between the input and output, and the
input and case. There is 500 volts (1500V for 48V Output) of isolation between the output and
case. Therefore, the unit may be mounted on any surface without fear of electrolysis or ground
fault.

POWER CONNECTION
The unit is supplied with power leads 1 meter long. This should normally be adequate to
connect to a source of power. If you must extend the power leads, be sure to use at least a
good quality (typeTEW) AWG12 wire. The wire colours are:
All connections should be made inside an appropriate junction box. Refer to the specications
table for the correct sizing of the circuit breaker in the distribution panel.
A ground stud is provided to bond the chassis to local ground to reduce or eliminate EMI.
To ensure spark free connections the power switch must be in the OFF position prior to making
the connections to the battery bank(s).
The unit may be hooked to 1 or 2 battery banks. If you are hooking up 2 battery banks keep in
mind that they MUST share a common ground!
Operation
Prior to turning on the unit, you must decide on which charging prole, 2 or 3 stage charging,
to use. To help you decide, please see the following section entitled 2 or 3 Stage Charging to
determine the charging prole.
Once you have decided on the charging prole you must set the switch to the correct
position. The switch is located to the right of the output terminal on the front panel. Set the
switch to the correct position as shown on the label.
To turn the unit on, simply move the power switch to the ON position. The alarm buzzer will
sound and the Low Output LED will come on briey, and then the green OUTPUT ON LED will
illuminate.
When the unit is rst turned on, it will charge the batteries at maximum current and the
charging light will be on. After a period of time which may be minutes to hours, the batteries
will reach the absorption voltage (3-stage) or oat voltage (2-stage), and the charging current
will reduce as necessary to maintain the batteries at that voltage. Once the charging current
has dropped to a low level (about 10% of the charging current rating), the charging light will
go off, and if set to 3-stage charging the voltage will drop to the oat level. You may check

This charger features user selectable 2 or 3 stage charging. The charging prole is selected by
moving the slide switch on the front panel up to 3 stage or down for 2 stage charging.
A two-stage charger provides a constant current until the battery reaches its rated capacity
and then switches to a “oat” voltage. The current then reduces as necessary to maintain
the battery at the oat voltage. The charger can be connected to the battery indenitely and
will provide the appropriate prole. A two-stage charger is recommended in most instances
since it is the most versatile and can be permanently connected to attenuate the characteristic
discharge of unused batteries. A load can be put on the battery or batteries without altering
its ability to keep the battery at optimal charge.

this voltage at the output terminals of the unit with a good digital voltmeter. As shipped from
the factory, the unit is preset for a oat voltage of 13.6, 27.2 or 36.3 VDC, which is generally
recommended for lead-acid batteries. The output adjust potentiometer is located to the right
of the 2 stage / 3 stage select switch. If you wish to adjust this voltage, reach in with a very
small at blade screwdriver to rotate the potentiometer. Please Note that this adjusts both the
oat and absorption voltages at the same time. Clockwise increases the output voltage, and
counter clockwise decreases it. It is advisable to check with the battery manufacturer before
changing the oat voltage.

A three-stage charger is the fastest charger. It charges the battery at a constant current
until the battery voltage reaches a slightly elevated level. The battery is maintained at
this voltage while the charging current diminishes to a low value, and then the battery is
switched to the oat voltage where it can be maintained indenitely. However, the charger
cannot differentiate between a current going to a load on the battery, or being absorbed by
the battery, so it can overcharge a battery supplying current to a load. A two-stage charger
is preferred for “loaded” batteries and a three-stage for idle or unloaded batteries during
recharging.
All of Analytic Systems’ chargers include adjustable output voltage for charging standard or
deep cycle lead-acid, VLRA or gel type batteries.
Meters
A high quality digital meter can be added to the voltage converter (factory installed only). The
meter shows simultaneous voltage and current on either of the two output terminals. A toggle
switch permits selection between the output terminals. The meter features bright red LED
readouts to permit easy monitoring from many feet or meters away.

Troubleshooting
If the red OVERTEMP LED and the audible alarm come on, the unit has overheated, and it
will shut down until it cools off sufciently. You may not have allowed sufcient space around
the unit for cooling, or there may be too many devices connected to the output of the unit.
Either reduce the number of devices connected to the unit, or reposition the unit for better
cooling. If necessary, direct a stream of moving air over the unit.
If the yellow LOW INPUT LED and the audible alarm comes on, the input voltage has
dropped to below a usable level.
If the LOW OUTPUT LED and the audible alarm come on, and the green OUTPUT ON LED
is completely off, the output of the unit has been shorted out, or there has been an internal
failure. Turn the unit off, disconnect all the loads connected to it, and turn it back on again.
If it comes on normally, turn it off again, reconnect one load, and turn it back on. Continue
reconnecting loads until the short circuit condition returns. Turn the unit off, disconnect the
faulty load, and reconnect it only after the fault is found and rectied. If the condition still
exists even after all the loads have been disconnected, the unit is defective, and must be
returned to the factory or an authorized service center for repair.
If the unit will not turn on at all, check the input fuse. To do this, rst turn off the unit and
disconnect the power cord. Next, remove the negative battery lead and cover the end with non
conductive material such as tape. Repeat this with the other battery lead. This will prevent an
accidental discharge from the battery. Remove the fuse and check it with an ohmmeter. If it is
blown, replace it with a new one. If that fuse blows as well or the unit still will not turn on, it
is defective, and must be returned to the factory or an authorized service center for repair.
If the batteries are hooked up backwards the output fuses will blow. To change them follow
the same procedure as for the input fuse.
If both the input and output fuses are good and the unit still does not function it must be
returned to the factory for servicing.
