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 pannel.
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.
