Fire-related instructions
CAUTION
Risk of injury from escaping
electrolyte
The battery modules in the
storage system are protected by
a number of security devices for
safe operation. Despite diligent
construction, cells inside the
battery modules can still degrade
or melt components in the event of
mechanical damage, heat, or a fault.
Possible effects include:
• Heating of battery modules.
• Escaping electrolyte fluid.
• Smoke, which can irritate skin,
eyes, and throat.
Consequently:
• Do not open battery modules.
• Do not physically damage
battery modules (puncture,
deform, disassemble, etc).
• Do not modify battery modules.
• Keep battery modules away from
water.
• Do not allow battery modules to
heat up.
• Only operate battery modules in
the allowed temperature range.
• Do not short circuit battery
modules or bring them into
contact with metal.
• Do not use a battery module
after it has short-circuited.
• Do not exhaustively discharge
battery modules.
If contents escape:
• Do not enter the room.
• Avoid contact with the escaping
electrolyte.
• Contact your fire department.
