1 Safety precaution
Read the manual carefully and operate in accordance with the safety precautions. Refer to local
safety regulations on items not covered in this manual. Electrical installation, maintenance must
be performed by professional / qualified personnel.
1.1 Storage and installation environment
 Handle the product gently, prevent from dropping
 Avoid open flame; keep away from flammables, explosives or corrosive chemicals
 Choose cool and dry place for storage and installation
 Prevent from water or humid intrusion
 Prevent from accidental access (children and animals)
 Do not step on the product packaging
 Do not place any foreign objects on top of the battery pack
 Do not store the battery pack upside down
1.2 Battery safety guidelines
 Prevent from electrostatic discharge
 Wear insulating gloves when handling batteries.
 Do not energize auxiliary power during installation
 Check the polarity carefully before switching on the system
 Defected or damaged batteries shall not be charged or discharged
Use the product only with inverters authorized by Sunwoda Energy, or consult
Sunwoda Energy's product engineers. For compatible list inverters, please visit:

1.4 Emergency handling
Wear personal protective equipment (PPE) such as goggle, facemask, insulated gloves and boots.
Evaluate the situation before taking remedy action. When it is safe to do so, disconnect external
AC or DC power connection.
Damaged or deformed battery enclosure
Risk of chemical leakage (i.e. electrolyte) and internal short-circuit.
Warning
Deformed or severely damaged battery pack can lead to piercing of cell pouch (chemical leakage)
or internal short-circuit (thermal runaway). The damaged battery pack can release toxic gas. Keep
away from it.
In case of accidental skin contact, wash the skin thoroughly with soap and seek medical advice. For
eye contact, wash under running water (~15 minutes) and require immediate medical attention.
Fire hazard
If the fire is not from the battery or not spread to the battery, use FM-200 or CO2 fire extinguisher
to put out the fire.
If the battery pack catches fire, do not attempt to put out the fire and evacuate immediately.
Seek medical in case of inhalation of pungent and toxic fumes.
Keep damaged batteries isolated and call your local fire department. Contact service for further
support.
Note：
1. If a fire occurs during battery charging, disconnect the battery pack circuit breaker and cut off
the power supply for charging under safe conditions.
2. If the battery string does not catch fire, extinguish the fire before the battery string catches fire.
3. If the battery pack catches fire, do not attempt to extinguish the fire. Evacuate immediately.

Water damage
Risk of electric shock and internal short-circuit. In case of splash or water spillage, when it is safe
to do so, dry the product. If any part of the battery system is submerged, keep away from water.
Do not reuse the submerged battery. Contact a service for support.
