SAVE THESE INSTRUCTIONS — This manual contains important safety and operating
instructions for the battery charger.
BATTERY CHARGER PRECAUTIONS
1. Do not expose the battery charger to rain or snow unless it is a sealed model.
2. 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.
3. Do not disassemble the battery charger; return it to the manufacturer or an authorized
service center when service or repair is required. Incorrect reassembly may result in a risk
of electric shock or re. Voltages in excess of 350 volts are present inside the charger any
time it is plugged into a power source, even if it is switched off.
4. To reduce risk of electric shock, unplug the battery charger from the power source before
attempting any maintenance or cleaning. Turning off controls will not reduce this risk.
5. Never place battery charger directly above battery; gases from battery will corrode and
damage battery charger.
6. Never allow battery acid to drip on to the battery charger.
1. WARNING — RISK OF EXPLOSIVE GASES
i. WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENER-
ATE 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 USER GUIDE AND FOLLOW THE
INSTRUCTIONS EXACTLY.
ii. To reduce risk of battery explosion, follow these instructions and those published by
the battery manufacturer and manufacturer of any equipment you intend to use in
vicinity of battery. Review the cautionary marking on these products.

pumps, debrillators, arrhythmia detectors and alarms, pacemakers, hemodialysis
systems, peritoneal dialysis systems, neonatal ventilator incubators, ventilators
for both adults and infants, anesthesia ventilators, and infusion pumps as well as
any other devices designated as “critical” by the U.S. FDA
iv. 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
v. NEVER smoke or allow a spark or ame in the vicinity of a battery.
vi. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark
or short-circuit the battery or other electrical part that may cause a re or explosion.
vii. 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 melt metal, causing a severe burn.
viii. NEVER charge a frozen battery.
ix. If it is necessary to remove a battery from service, always remove grounded terminal
from battery rst. Make sure all accessories connected to the battery are off, to
prevent an arc when reconnecting the new battery.
x. Be sure area around battery is well ventilated.
xi. Clean the battery terminals. Be careful to keep corrosion from coming in contact
with eyes.
xii. Study all the battery manufacturer’s specic precautions such as removing or not
removing cell caps while charging and recommended rates of charge

Installation
MOUNTING
Mount the unit in a DRY location. Allow at least 1 inch of clearance for adequate cooling.
POWER CONNECTION
The unit is supplied with input power leads 1 meter long. This should normally be adequate to
connect to a source of power. If you must extend the cable:
• Use the smallest extension length possible.
• Use no less than 10 gauge conductors.
• Splice and solder the joints.
• Protect the joints with heat shrink tubing.
Connect the wires as follows:
• Red to Positive
• Black to Negative
POWER CONNECTION
Two positive output terminals and two negative output terminals are provided. Connect only
one wire to each terminal.
Note that the current specications are for input current. To obtain the maximum output
current capability at any given input voltage, use the following formula:
Output Current = Input Volts / Output Volts x 26
For example:
10 VDC in and 27 VDC out, the max output current = 10/27 x 26 = 9.6 Amps.
20 VDC in and 27 VDC out, the max output current = 20/27 x 26 = 19.3 Amps
It is recommended to parallel the output connections if the unit is used as a single bank battery charger.

7
Turn the power switch on the front of the unit on to energize the outputs.
If you wish to adjust the output voltage, rst attach a good digital voltmeter to the output
terminals to monitor the voltage. Next, remove the cover plate (secured by 2 screws) to expose
the output adjust potentiometer. Reach in with a very small at blade screwdriver to rotate
the potentiometer. Clockwise increases the output voltage, and counter clockwise decreases
it. When you are done, replace the cover plate and securely tighten the screws. Remove the
voltmeter from the output terminals.
Operation
Troubleshooting
If the load exceeds the continuous rating for too long a period, the internal temperature sensor
will cause the unit to stop boosting the input voltage until the unit has cooled down. After the
unit has cooled down, normal operation will resume.
If the input voltage drops below the specied minimum input, the unit will sound the alarm.
If the output voltage drops below the specied minimum, the unit will sound the alarm.
If the current demanded by the devices connected to the unit exceed the maximum current
rating, the fuse will blow.
If the fuse blows with no load connected, check that the power leads are connected to the
battery with the correct polarity; if they are then the unit is damaged and must be returned for
repair.

8
Dry Contact Relay
To use your dry contact output fail relay you must connect a 9-pin D connector to the unit. You
must use pins one and six as is indicated on page 7 in the remote connector diagram.
The relay is factory preset to fail in the closed position when the low output LED and buzzer
come on. If you wish to have the relay fail in the open position when the low output LED and
buzzer come on, you must take the cover off the unit and move the jumper to the other position
on J11. J11 is located next to the relay.
To change the position of the jumper, rst turn the unit off and disconnect the unit from both
the power and batteries. Next, turn the unit on for 30 seconds to discharge the capacitors, and
then turn it off again. Remove the six screws holding on the cover, turn the unit upside down,
remove the cover and locate J11. It will be next to the relay as is shown in the above diagram.
Simply move the jumper to the desired position as is shown in the above diagram. Replace the
cover and re-install the four screws. Reconnect the unit to the power and batteries.
Remote Control Option
A remote control panel may be connected to
the converter using a 9-pin D-connector, which
attaches to the side of the battery charger.
The remote control panel and D connector are
part of the remote control option. The remote
control panel allows the unit to be operated
remotely as well as duplicating all the
diagnostic indicators and audible alarm.
REMOTE CONNECTOR
This connector is located on the side of the unit. Important: To prevent the possibility of High
Voltage Electrical Shock, do not power up the battery charger unless all wiring from the unit
to the remote is securely connected. Do not remove the dust cover from the DB-9 connector if
the remote is not being used.
IMPORTANT: This remote is to be used only on Battery Chargers manufactured by Analytic Systems.

*The Actual charging rate depends upon the input/output voltage ratio. To obtain the charging capacity
at any given input voltage, use the following formula: Charging Current = Input Volts/Output Volts x 26
For example, at 10.5VDC in and 13.6VDC out, the charging current = 10.5/13.6 x 26 = 20.1 amps
