OPERATING MANUAL
Do not operate the battery charger unless you have read and
understood the details of this operating manual.
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS – This manual contains important safety and
operating instructions for battery charger Models CBSW1-S 24/12, CBSW2-S
24/25 and CBSW2-S 48/20.
Before using the battery charger, read all instructions and cautionary markings on the charger,
battery pack, and product powered by the battery.
CAUTION – To reduce risk of injury, charge only the type of batteries indicated on the charger.
Other types of batteries may burst causing personal injury and damage.
GENERAL INFORMATION
This device is an electronic battery charger with microprocessor control.
Charging process is fully automatic, protected against overload, short-circuit, reversed
polarity and overtemperature.
These charger are intended only for stand alone use, not onboard vehicles.
WARNINGS
This charger should not be used by persons with a lack of experience and knowledge on
electrical systems and battery charging unless they have been trained by and/or supervised by
a suitably knowledgeable and experienced person.
Before starting to charge, make sure the voltage of the charger matches the voltage of the
battery, that the charging current suits the capacity of the battery and that the selected
charging curve is correct for the type of battery to be charged.
Make sure the rated input voltage of the charger suits the available supply voltage.
Danger: Risk of electric shock.
Make sure the AC supply is grounded.
Make sure the AC supply cord is in good condition and that it is securely connected to the
charger before use.
Make sure the DC cables and DC connector are good condition before use.
Do not use the battery charger if there are any signs of physical damage that may have
affected the integrity of the case, exposing internal components.

Never disconnect the battery while charging: this could cause sparks.
Never use the equipment in the rain, in areas used for washing down equipment or in damp
areas.
Gases generated by some battery types during charging are explosive. Do not smoke in the
vicinity of the batteries.
Do not operate the charger in an explosive environment.
Do not operate the charger near flammable liquid such as gasoline, oil or other volatile
substances.
Do not use on damaged battery packs.
Never charge a frozen battery.
Pay attention to any warnings provided by the battery manufacturer and equipment
manufacturer.
HEALTH HAZARD
Use protective glasses and gloves during battery maintenance. A damaged or leaking battery
can cause chemical burns on contact.
In case of contact with battery acid, wash the affected parts with fresh water and seek
medical attention.
OPERATION
IMPORTANT:Check that the battery type setting of the charger is suitable for the battery type
Check the polarity of the battery pack, and connect to the battery charger to the batteries.
Plug the charger into the AC supply.
Turn on the charger via the ON/OFF switch.
The charger will display the following during start-up:
“bti”
the firmware version number in 3 successive screens, example:
o010-
o093-
o001
The nominal voltage setting, example: 24.0U
The current setting, example:12.0A
The selection of charging curve memory location, example: 014c
An indicator of the battery type setting, example: AGM
The charger will then ready the battey pack voltage, example: 25.2U
If the battery pack voltage cannot be read, the error “bat” will be shown.
If all is OK, a relay click will be heard, and the output begins with the bulk charging phase, with
the red led ON.
When the red led is ON and the yellow led is ON, the charger is in the second phase.
When the yellow led is ON the charger is in the third phase
When the green led is ON, the charger is in the final phase and it indicates the charge is
complete.
Before using the batteries, turn off the charger and disconnect the AC power to the charger,
then disconnect the charger from the battery pack.
If errors occur, the charging process will stop and an error code will be shown on the display.
See the table of errors on the following page.
CHARGING DATA
During the charging process, and before turning off the charger, it is possible to see data
relating to the charge cycle by sequentially pressing the “Press for Status” pad. This will
show, in turn:
Current (A)
Charge voltage (V)
Charging time (Hours)
Amp hour capacity returned to the battery (Ah)
Power returned to the battery in kilowatt-hours (KWh)
