SECTION 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 located 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.
