Fire-related instructions

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 catch fire in the event of mechanical damage, heat, or a fault. Possible effects
include:
• Heating of battery modules.
• Escaping electrolyte, which can ignite and produce an explosive flame.
• 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 (except to extinguish a fire in the storage
system).
• 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.
Despite all of the care that goes into the design of the storage
system, fires are still possible. A fire can release substances
contained in the battery modules.
In the event of a fire in the storage system or its surroundings:
• Only fire fighters wearing proper protective clothing
(including gloves, masks, and breathing apparatus) may enter
the room with the burning storage system.
• A fire in the storage system can be extinguished by
conventional agents.
• The use of water is advisable to cool the battery modules and
thus prevent the thermal runaway of modules that are still
intact.
Pertinent information on battery modules include:
• The battery modules have a rated voltage of 51.2 VDC and
are thus in the range of protective extra-low voltage (below
60 VDC).
• The battery modules contain no metallic lithium.
