Safety
DANGER!
- This warning indicates an immediate hazard which will lead to death or serious
injury may occur.
(1) Electrical Shock
Do not touch the terminals of the battery module without protectors.
Be grounded with the specified conditions.
High voltage may occur between the positive and the negative terminals.
Electric shock impairs health or may cause threat to life.
More than 2,000 meters higher, risks of an electric shock will be increased.
(2) Immersion
Do not immerse the battery module in liquid such as water, beverages, or
other fluids.
Do not expose to corrosive substances such as sea breeze, steam or chemicals.
Do not install in the humid places or places to condensation.
Exposure to liquid may damage the battery module or the circuit board.
This may cause a battery module's damage to leak electrolyte, generate
heat, smoke, catch fire, or explode.
