2. OPERATION PROCEDURE
2.1 Ensure the type and output voltage before
power on.
2.2 Connect charger-line (accessory) with +/−
terminals.
Warning : +/−terminals should not be shorted!
2.3 Plug in then switch on, voltage meter should
be read by 13.8V(12V) / 27.6V (24V).
2.4 If output voltage correct then power off.
Connect the red side of the charger-line to the
“+” terminal of the battery, the black one to the
“−” terminal.
2.5 Power on then charging is starting, the more
charge current the less time needed, current is
adjusted by current-adjust-knob on the panel.
For the long time charging, we suggest the
current less than 1A.
2.6 Factory setting of output voltage is 13.8V or
27.6V, on the conditon of old batteries the
voltage can be boost by turning the VR from
the hole loacted on the panel.
CAUTION!! High voltage will cause batteries
liguid vaporized and batteries
damaged.
2.7 Our charger has voltage-feedback-sensor to
avoid batteries be over-charged, if the battery
is full charged then output current will be
reduced to zero, in order to extend the life of
the battery.

3. NOTICES
3.1 Avoid to place the charger in the environment
such as high temperature, humidity, acid &
alkali, Prevent from insolation, drench and
caustic.
3.2 AC input voltage should fit the charger type.
We suggest to install a protection device (such
as MCCB) inter AC power and charger.
3.3 Never depart the charger.
3.4 Never change internal wiring of the charger.
3.5 Never adjust internal VRs of the PCB
intentionally.
3.6 Routine-check of output voltage is necessary
3.7 Terminals of the charger and polarities of the
battery should be connected correctly, red to
“+”, black to “−”.
Warning : Never short “+” (red terminal) and
“−” (black terminal) polarities.
3.8 Please operate the charger under the max.
maximum capacities.
3.9 Beside charge battery, please do not use
charger for other purpose.
3.10 When install the output connect wires, please
references the figure below.

5. TROUBLESHOOTING
1. Check AC Power.
2. Check fuse.
3. Charge-line if poor connection or not.
4. Check if short exists or not .
No output voltage
5. Check if polarities are oppositely or not.
1. Check if battery is full charged or not.
2. Check if poor connection exists or not.
3. Check if the type and the rate of the charger are correct or not.
No charge current or
current Can’t be
adjusted 4. Check if battery is out of order or not.
※
If the step above can’t make the charger working still please contact with us.
