3.
The grounding wire must be connected to ensure the plug is properly earthed.
4.
Keep the charger level and right side up while charging,
5.
As the casing can generate heat during charging, it is prohibited to cover the vent of casing.
6.
The instructions for the battery and transportation tools should be strictly followed while charging.
7.
The battery should only be mounted or dismantled after the power is turned off.
8.
The maintenance work for the charger should be done by the professionals.
9.
A fuse and cable with the same specifications should be used when they need to be replaced.
10.
As sulfuric acid gas, hydrogen and oxygen, which are strongly corrosive, can be generated while
charging, the battery should be charged inside a well-ventilated room. Flames and sparks should be
kept away and smoking is prohibited.
11.
The power socket should be connected to the grounding wire to ensure the power cord is properly
earthed.
12.
The battery should only be mounted or dismantled after the power is turned off.
13.
When electrified, the battery clamps should not be contacted with each other.
14.
The cover of battery should
never
be opened while charging.
15.
It is prohibited to connect the battery clamps the wrong way around.(e.g., never connect the red
clamp of anode to the cathode of battery, or connect the black clamp of the cathode to the anode of
battery)
16.
It is prohibited to use the charger for the charging of non-charging batteries.
17.
Only fuses of the same specification 80A or 100A, when replaced, may be used, otherwise the
warranty will be void. A set of replacement fuses is supplied with each unit.
18.
In case the power cable is damaged, the damaged cable should be dismantled and replaced by
professionals.
OPERATION INSTRUCTIONS FOR CHARGER AND BATTERY
To ensure that the charger and battery are used correctly and the machine is in good condition, the
following rules must be followed:
1. Operation instructions for the battery
When battery does not have sufficient charge, its’ terminal voltage remains the same, which means
a 12V battery has the terminal voltage of 12V and a 24V battery has the terminal voltage of 24V. The
main physical phenomenon indicating insufficient charge in the battery is the difference in specific
gravity of the battery solution. Normally a battery has sufficient charge when the specific gravity of
the battery solution is 1.28KG/L. If it is lower than 1.16KG/L, the battery is empty and won’t have any
electricity.
The voltage of battery deviates from the normal value only when the battery is loaded or charged.
When loaded, the voltage is higher than its’ usual value of terminal voltage.
If the battery is topped for some time (about 10-30 minutes) after it is loaded, and the terminal voltage
is still lower than normal value, the battery may have quality defects.
Remove the cover of the battery to see if there is sufficient electrolytic solution. If not, add distilled
water.
As the electrolytic solution in the battery is dilute sulfuric acid and strongly corrosive, avoid contact
with your skin or clothes. In case electrolytic solution was in contacted with your skin, wash the
affected area with water immediately and seek medical attention.
2. Correct charging method
It is possible to charge the batteries with the same capacities in parallel connection or when
connected in series.
