Battery Short Circuit
Battery short circuits can generate high instantaneous current and release a great
amount of energy, which may cause equipment damage or personal injury.
●
●
Flammable Gas
● Do not use unsealed lead-acid batteries.
● To prevent fire or corrosion, ensure that flammable gas (such as hydrogen) is
properly exhausted for lead-acid batteries.
Lead-acid batteries emit flammable gas when used. Ensure that batteries are kept
in a well-ventilated area and take preventive measures against fire.
Battery Leakage
Battery overheating causes deformation, damage, and electrolyte spillage.
Issue 01 (2021-05-30)
Install batteries in a dry and cool environment with good ventilation, which is
away from high temperature and flammable materials, and take precautions
against fire.
Place and secure batteries horizontally.
Note the polarities when installing batteries. Do not short-circuit the positive
and negative poles of the same battery or battery string. Otherwise, the
battery may be short-circuited.
When installing a battery string, retain at least one breakpoint to prevent a
loop being formed. After checking that the installation is correct, close the
breakpoints to finish the installation.
During the installation, insulate the terminals of cables connecting batteries.
Ensure that the terminals do not come into contact with metal components
such as the cabinet.
Secure battery cables or copper bars by tightening bolts to the required
torque. Loose connections will result in excessive voltage drop or cause
batteries to burn out in the case of excessive current.
Check battery connections periodically, ensuring that all bolts are securely
tightened.
D ANGER
If permitted, disconnect the batteries in use before performing any other
operations.
To avoid battery short-circuit, do not maintain batteries with power on.
