If no battery is involved, skip this section.
Before installing, operating, or maintaining batteries, read the battery
manufacturer's instructions. Observe the safety precautions provided in this
document which are supplemental to the safety instructions provided by the
battery manufacturer.
Basic Requirements
Before operating batteries, carefully read the safety precautions for battery
handling and master the correct battery connection methods.
● Do not expose batteries at high temperatures or around heat-generating
sources, such as sunlight, fire sources, transformers, and heaters. Overheating
may cause battery explosion.
● Do not burn batteries. Otherwise, the batteries may explode.
● To avoid leakage, overheating, fire, or explosions, do not disassemble, alter, or
damage batteries, for example, insert sundries into batteries or immerse
batteries in water or other liquids.
● When replacing a battery, use a battery of the same model or type. Improper
replacement may cause the battery to explode.
● 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.
To ensure safety during battery installation, operation, and maintenance, pay

Move or lift the equipment by holding its handles or lower edges. Do not hold
the handles of modules (such as power supply units, fans, and boards) that
are installed in the equipment because they cannot support the weight of the
equipment.
D ANGER
Do not wear conductive articles such as watches, bracelets, bangles, and rings.
Wear goggles, rubber gloves, and protective clothing to avoid damage caused
by electrolyte in the case of electrolyte overflow. If a battery overflows,
protect the skin or eyes from the leaking liquid. If the skin or eyes come in
contact with the leaking liquid, wash it immediately with clean water and go
to the hospital for medical treatment.
Use dedicated insulated tools.
Move batteries in the required direction. Do not place a battery upside down
or tilt it.
Keep the battery loop disconnected during installation and maintenance.
Do not drop, squeeze, or puncture a battery. Protect batteries from external
high pressure to prevent internal short circuits and overheating.
