1.6.3 Protection Against Battery Short Circuits

Issue 02 (2019-08-30)
Do not connect a metal conductor to the battery poles or touch the battery terminals.
Otherwise, the battery may be short-circuited and heat up, which can cause injuries such
as burning.
Dispose of batteries in accordance with local laws and regulations. Do not dispose of
batteries as household waste. If a battery is disposed of improperly, it may explode.
Do not drop, squeeze, or puncture a battery. Protect batteries from external high pressure
to prevent internal short circuits and overheating.
Do not use damaged batteries.
To prevent injury or explosion, do not allow children or pets to swallow or bite a battery.
If batteries experience discoloration, deformation, abnormal heating, or other
abnormalities during working, charging, or storage, stop using the batteries and replace
them with new ones.
Secure battery cables or copper bars to the torque specified in battery documentation.
Loose connections will result in excessive voltage drops or cause batteries to burn out
when the current increases.
Lead-acid batteries emit flammable gas when used. 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. High battery temperature may result in
battery distortion, damage, and electrolyte overflow.
Switch off the power supply before installing batteries.
Note the positive and negative polarities when installing batteries. Do not short-circuit
the positive and negative poles of the same battery or battery string. Otherwise, a great
amount of energy is released, causing personal injury and damage to equipment.
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.
Before powering on a battery string, ensure that all bolts connecting batteries are
tightened to the required torque.
Do not use unsealed lead-acid batteries. Place and secure lead-acid batteries horizontally
to prevent device inflammation or corrosion due to flammable gas emitted from
batteries.
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.
When handling a battery, ensure that its electrodes are upward. Do not tilt or overturn
batteries.
