1.2 Safety instructions
For safety reasons, installers are responsible for familiarizing themselves with the contents
of this document and all warnings before performing installation.
1.2.1. General safety precautions
Over-voltages or wrong wiring can damage the RESU10M(hereinafter “battery pack”)
and cause deflagration, which can be extremely dangerous.
All types of breakdown of the product may lead to a leakage of electrolyte or
flammable gas.
Avoid installing the battery pack where flammable materials are stored. Do not
install in places where explosive gas or chemicals are present.
During installation of the battery, the utility grid, solar input must be disconnected
from the Battery Pack wiring. Wiring must be carried out by a qualified personnel.
Battery Pack is not user serviceable. High voltage is present in the device.
The electronics inside the Battery Pack are vulnerable to electrostatic discharge.
Be sure to be grounded before handling the battery pack.
Read the label with Warning Symbols and Precautions, which is visibly under to the
Battery Cover (see Section 1.3)
1.2.2. Battery handling guide
Store the product out of reach of children and animals.
Store the product where it should be minimal dust and dirt in the area.
Store at cool and dry place. (Do not store in greenhouses and storage areas for hay,
straw, chaff, animal feed, fertilizers, vegetables of fruit products.)
Store the product on a flat surface.
Do not store this product in a place exposed to direct sunlight.
Do not store the battery pack upside down on the ground.
If the battery pack is installed in the garage then ensure the product is above the
height of the vehicle bumper and/or door
Do not connect the power cable at terminal block opposite direction.
Do not put the battery pack upside down on the ground.
Do not expose battery to open flame.
Do not expose or place near water sources like downspouts or sprinklers.
Do not place the product nearby highly flammable materials. It may lead to fire

or explosion in case of accident.
Do not disconnect, disassemble or repair by unqualified personnel.
Services must be made by qualified personnel only.
Do not step on the product or the product package. The product may be damaged.
Do not place any foreign objects on the top of the Battery
Do not charge or discharge damaged battery.
Do not connect any AC conductors or Photo-voltaic conductors directly to the
battery pack and should be only connected to the Inverter.
The battery pack has been certified IP55 and can be installed indoors as well as outdoors.
However, if installed outdoors, do not allow the battery pack to be exposed to direct
sunlight and water source as it may cause :
- Power limitation phenomena in the battery
(with a resulting decreased energy production by the system)
- Premature wear of the electrical/electromechanical components and
mechanical components.
- Reduction in performance, service life and possible damage of the battery
A ventilated area is strongly recommended for handling the product.
Only use the product with a LGC-authorized inverter. For a list of compatible
inverters, go to : http://www.lgesspartner.com
Do not touch if liquid is spilled on the product. There is a risk of electric shock.
Handle the battery wearing the insulated gloves.
Do not damage the unit in such ways as dropping, deforming, impacting, cutting
or penetrating with a sharp object. It may cause a leakage of electrolyte or fire.

1.2.3. Response to emergency situations
The battery pack comprises multiple batteries that are designed to prevent
hazards resulting from failures. However, LG Chem cannot guarantee their absolute safety.
If a user happens to be exposed to internal materials of the battery cell due to damage
on the outer casing, the following actions are recommended.
Inhalation : Leave the contaminated area immediately and seek medical attention.
Eye contact : Rinse eyes with running water for 15 minutes and seek medical
attention.
Contact with skin : Wash the contacted area with soap thoroughly and seek
medical attention.
Ingestion: Induce vomiting and seek medical attention.
If a fire breaks out in the place where the battery pack is installed, perform the following
countermeasures:
Fire extinguishing media
Respirator is not required during normal operations.
Use FM-200 or CO2 extinguisher for battery fire.
Use an ABC fire extinguisher, if the fire is not from battery and not spread to it yet.
Fire -fighting instructions
1. If fire occurs when charging batteries, if it is safe to do so, disconnect the battery
pack circuit breaker to shut off the power to charge.
2. If the battery pack is not on fire yet, extinguish the fire before the battery pack
catches fire.
3. If the battery pack is on fire, do not try to extinguish but evacuate people
immediately.
Effective ways to deal with accidents
On land : Place damaged battery into a segregated place and call local fire
department or service engineer.
In water : Stay out of the water and don’t touch anything if any part of the battery,
inverter, or wiring is submerged.

Do not use submerged battery again and contact the service engineer.
