Operating Method
1. Before using, check that the power voltage (AC 220-240V, 50/60Hz) is correct and connect to a
power outlet.
2. Connect the battery fuse breaker to the battery input terminal of this device, connect the 24V battery,
and turn on the battery fuse breaker.
3. When power is applied. After checking whether the battery voltage is within the charging range
(16V ≤ VBATT ≤ 28.5V), charging starts.
4. If the battery connected to the device is completely discharged, it will not be charged.
Features
- AUTOMATIC CHARGING
When charging, it is charged up to 10A according to the internal setting value, and the current de-
creases as it approaches the full charge voltage (27.3V@25℃, overseas model), and the current drops
at full charge to maintain the charged state.
- AC/DC/BATT STATUS DISPLAY
AC/DC/BATT abnormality can be monitored through the front two-color LED and rear NO/NC contact
terminals.
- MONITORING CHARGING STATUS
User can monitor the charging voltage through a windows program.

Equipment Setting and Checking
Equipment Setting and Checking
1. Address Setting
1) Set the equipment numbers for each deciding condition using the rear panel DIP switch.
- If the number is already in-use, the system will not function properly.
- Please check the equipment number set-up status. (can be expanded up to 15 equipments)
2) Setting should be as table below, and if data number is added to switch which is On, it will be
the equipment number.
(Ex: when number 1 and 3 is ON, 1 and 4 is added, so equipment number will be 5.)
2. TERMINATION Switch (LOAD/OPEN) Setting
1) For the system linked by using RS-485 communication interface, it is necessary to set the termina-
tion switch (LOAD/OPEN) on the rear panel to stabilize data transfer.
2) Set the termination switch to LOAD only for the first and last-numbered equipment units.
All others must be set to OPEN.

- Beep
When each error signal occurs, a warning sound is generated together with the purpose of drawing
the attention of the manager.
Short press the BUZZER OFF button once to turn off the beep
(※Note: Errors are not cleared.)
When the status of each error signal changes, the beep sounds again if other warnings remain.
When all error conditions are resolved, the warning sound is automatically turned off.
- Cancellation and restoration of warning sound mode
To cancel the beep mode, press the BUZZER OFF button for about 5 seconds. The beep mode is re-
leased with a beep sound. To enter the beep mode again, press the BUZZER OFF button for about
3 seconds. It switches to the beep mode with a beep sound.
5. CONFIRM BUTTON
After applying AC power, the battery reaches the output voltage steady state for about 20 seconds.
If the battery is connected, you can save the initial impedance value for checking the battery imped-
ance by pressing the corresponding button.
During the first impedance confirmation, the BATT LED blinks green/orange several times.
If the impedance increases by about 100mohm from the stored value, a warning is activated when
checking the impedance.
Impedance warning repeats with a short cycle of beeps.

Equipment Setting and Checking details
Equipment Setting and Checking details
1. INSTALLATION
Before installing the battery charger into a 19-inch rack, you must perform battery jumper settings.
1) Battery Jumper settings
The battery charging current can be set to 3A/5A/7A/10A according to the battery capacity.
In the factory default setting, the jumper is set to the '3A' position.
(※Caution: Before installation, before all power is connected, it must be operated only by a qualified
technician.)
2) Battery Connection
The total battery value must be 24VDC.
Observe the following when connecting multiple batteries.
- Use only batteries of the same voltage, capacity, type, brand and condition of aging.
- Always connect the batteries in series.
- Always check the relevant standards for details when connecting multiple batteries.
- Always use the battery fuse breaker as close to the battery as possible.
3) Connecting the temperature sensor
The battery charger has one socket for connecting the temperature sensor (included with the system).
➊Insert the plug of the temperature sensor into the socket of the temperature sensor.
➋Attach the sensor body close to the battery. A good thermal connection is essential for accurate
temperature information.
For example, if you connect two 12V batteries in series, attach the sensor between the two bat-
teries.
※The applied charging voltage and current is temperature dependent. So always use a temperature
sensor. If the temperature sensor is not used (or used incorrectly), the battery may be damaged or
the battery life may be reduced.
※If the temperature sensor is disconnected, disconnected or shorted, the voltage will be calibrated
for 25°C.
4) AC Power Connection
The battery charger can be connected to 220-240VAC +/- 10%.
※Use the battery fuse breaker to connect or disconnect the battery charger from the device.
2. CONFIGURATION
1) Battery Charging
In normal operating mode: The battery charger charges the battery and displays its status when fully
charged. The maximum current that can be provided for battery charging (CHG) and auxiliary out-
put (AUX) is 15A. When in backup operating mode: the battery provides the total operating current,
which must not exceed 120A.

BATTERY CHARGER
10 PB-6207B
3. OPERATION
1) Working Principles
- The battery connection test is performed in the following way.
- The battery connection test is performed every 20 minutes after operation.
- An error is generated when the battery appears to be missing.
The battery impedance check is measured once every 20 minutes from 30 seconds after AC power
is applied to the battery charger. When connecting the battery for the first time, an initial value storage
process is required, and an error is generated if the threshold level is exceeded after comparing with
the stored value.
2) Low battery voltage protection
Voltage threshold is 19.6VDC ± 10% for PB-6207B.
- Discharge when there is no AC power to the battery charger
Battery Charger When discharging without AC power, the battery charger discharges the battery
to 19.6V. Undervoltage protection is activated. That is, the battery charger turns off and all outputs
are shut down.
4. SYSTEM OPERATION
To avoid starting problems with the battery charger, the main output current < 9 A, the auxiliary
output current < 9 A, and the total output current < 14 A.
●Please use the following procedure to operate your system.
➊Turn on AC power circuit breaker (battery fuse breaker off).
➋Check the output voltage of the auxiliary output.
- Auxiliary output (AUX) : ~ 24.3VDC
➌Turn on the battery fuse breaker. The battery relay is activated in up to approx. 20 minutes.
➍If the 3 LEDs on the front panel are green, the battery charger is working properly.
5. MAINTENANCE
Maintenance must only be carried out by qualified personnel.
6. CAUTION
Before removing and opening the battery charger housing, check the following.
- The AC power circuit breaker must be in the off position.
- The battery fuse breaker must be in the off position.
- All connections must be disconnected.
➊Check the battery periodically. Consult your battery supplier's specifications and guidelines.
➋Periodically wipe the battery charger with a clean, dry cloth.
➌Prevent dust from accumulating on the fan and air intake.
7. WARNING
There is a risk of explosion if the original battery is replaced with an incorrect type of battery.
Used batteries must be disposed of according to recycling requirements.
