4-4. Protection


Short-circuit protection: It will not be damaged even the output terminal is short-circuited.

Reverse connection protection: It will not be damaged even battery is reversely
connected.

Over temperature protection: Fan spins when charger internal temperature rises above a
certain level, and switches to strong or weak automatically depending on the temperature. Fan
stops when the temperature drops beyond a certain level. However, once the temperature rises
higher than the general level, LED turns to error display. Leave it for a while and wait for the
temperature drops to the normal level; charger recovers and charging restarts.

Input protection: An abnormal current flow in internal charger because of the charge itself or
other external factors, the protection works by melting the fuse of the input power.

Output protection: Due to the trouble of charger itself or other external factors, abnormal
current flows between the charger and battery. The fuse gets melt to protect the charger and
safety.
Possible cause

Connect charging clips to the battery.

Contact us or the distributor if
charging clips connected and charger
still errors.
Check if the battery voltage is available for
the charger. (Refer to P.6)
The temperature sensor is error. Contact
us or the distributor.
Wait for the charger to cool down. It
restarts automatically after temperature
down.
Contact us or the distributor.
