Battery pack short circuits can generate high instantaneous currents and release a great
amount of energy, which may cause equipment damage or personal injury.

When installing and maintaining battery packs, wrap the exposed cable terminals on the
battery packs with insulation tape.

Avoid foreign objects (such as conductive objects, screws, and liquids) from entering
battery packs, as this may cause short circuits.
Hazard and Toxicity Description

Hazard: Contact between battery pack terminals and other metal objects may cause heat or
electrolyte leakage. The electrolyte is flammable. If the electrolyte leaks, move battery
packs away from fire sources immediately.

Toxicity: Steam produced by battery pack burning may irritate eyes, skin, and throat.
Battery Pack Troubleshooting Measures

Avoid contact with leaked liquids or gases in the case of electrolyte leakage or abnormal
odor. Keep non-professionals away. Contact professionals immediately. Professionals must
wear safety goggles, rubber gloves, gas masks, and protective clothing.

Electrolyte is corrosive and can cause irritation and chemical burns. If you come into
contact with the battery electrolyte, do as follows:

Inhalation: Evacuate from contaminated areas, get fresh air immediately, and seek
immediate medical attention.

Eye contact: Immediately wash your eyes with water for at least 15 minutes, do not rub
your eyes, and seek immediate medical attention.

Skin contact: Wash the affected areas immediately with soap and water and seek
immediate medical attention.

Intake: Seek immediate medical attention.

When a battery pack is dropped (with or without packaging) but the appearance is not
deformed or damaged, and there is no obvious abnormal odor, smoke, or fire, ensure
safety and perform the following operations:
− Warehouse: Evacuate personnel, transfer the battery pack to an open and safe place
by professionals using mechanical tools, and contact the Company's service
engineers. Leave the battery pack for an hour and wait until the battery pack
temperature is within room temperature±10°C before handling.
− ESS onsite: Evacuate personnel, close the doors of the ESS, transfer the battery
pack to an open and safe place by professionals using mechanical tools, and contact
