Battery handling guide
• Use the battery pack only as directed.
• Do not use the battery pack if it is defective, appears cracked, broken or
otherwise damaged, or fails to operate.
• Do not attempt to open, disassemble, repair, tamper with, or modify the
battery pack. The battery pack is not user serviceable.
• To protect the battery pack and its components from damage when trans-
porting, handle with care.
• Do not impact, pull, drag or step on the battery pack. Do not subject it to
any strong force.

1.3 Response to emergency situations
The RESU battery pack comprises multiple batteries that are designed to pre-
vent hazards resulting from failures. However, LG Chem cannot guarantee
their absolute safety.
Leaking batteries
If the battery pack leaks electrolyte, avoid contact with the leaking liquid or
gas. Electrolyte is corrosive and contact may cause skin irritation and chemical
burns.
7

Saftey
If one is exposed to the leaked substance, do these actions:
Inhalation: Evacuate the contaminated area, and seek medical attention im-
mediately.
Eye contact: Rinse eyes with owing water for 15 minutes, and seek medical
attention immediately.
Skin contact: Wash the aected area thoroughly with soap and water, and
seek medical attention immediately.
Ingestion: Induce vomiting, and seek medical attention immediately.
Fire
In case there is a re, always have an ABC or carbon dioxide extin-
guisher.
WARNING
The battery pack may catch re when heated above 150°C.
If a re breaks out where the battery pack is installed, do these actions:
1. Extinguish the re before the battery pack catches re.
2. If it is impossible to extinguish the re but you have time, move the battery
pack to a safe area before it catches re.
3. If the battery pack has caught re, do not try to extinguish the re. Evac-
uate people immediately.
WARNING
If the battery catches re, it will produce noxious and poisonous gases. Do
not approach.
Wet batteries
If the battery pack is wet or submerged in water, do not try to access it. Contact
LG Chem or your distributor for technical assistance.

Saftey
Damaged batteries
Damaged batteries are dangerous and must be handled with extreme caution.
They are not t for use and may pose a danger to people or property.
If the battery pack seems to be damaged, pack it in its original container, and
then return it to LG Chem or your distributor.
CAUTION
Damaged batteries may leak electrolyte or produce ammable gas. If you
suspect such damage, immediately contact LG Chem for advice and infor-
mation.

Installation
CAUTION
Make sure that the battery pack is always exposed to the ambient air. The
battery pack is cooled by natural convection. If the battery pack is entirely
or partially covered or shielded, it may cause the battery pack to stop oper-
ating.
3.8 Securing the battery pack to a wall
Secure the battery pack to a wall to prevent the battery pack from moving. If
the battery pack is installed above the oor or on a platform, make sure that
the wall or platform is capable of supporting the battery pack’s weight.
To mount the battery pack to a wall, take the following steps:
ON
