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 and servicing.
1.2.1 General Safety Precautions
Over-voltages or wrong wiring can damage the battery pack and cause combustion which can
be extremely dangerous.
Any type of product breakdown may lead to a leakage of electrolytes or ammable gas.
Avoid installing the battery pack where ammable materials are stored. Do not install in places
where explosive gas or chemicals are present.
During installation of the battery, the utility grid and solar input must be disconnected from the
Battery Pack wiring. Wiring must be carried out by qualied personnel.
Battery pack should only be serviced by qualied personnel.
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 are visible under the Battery
Cover (see Section 1.3 Warning Label).
1.2.2 Battery Handling Guide
• Do not expose the battery to an open ame.
• Do not place the product near to highly ammable materials.
• Do not expose or place near water sources such as downspouts or sprinklers.
• Do not store or install the product in direct sunlight.
• Do not install the product in an airtight enclosure or in an area without ventilation.
• Do not install the product in living area of dwelling units or in sleeping units other
than within utility closets and storage or utility spaces.
• Store in a cool and dry place. (Do not store in greenhouses or storage areas for
hay, straw, cha, animal feed, fertilizer, vegetables, or fruit products.)
• Store the product on a at, level surface.
• Store the product out of reach of children and animals.
• Store the product in clean environment, free of dust, dirt and debris.
• Do not disconnect, disassemble or repair the product unqualied personnel. Only
qualied personal are to handle, install and service the Product.
• Do not damage the Product by dropping, deforming, impacting, cutting or
penetrating with a sharp object. Doing so may cause a re or leakage of
electrolytes.
• Do not touch the product if liquid spills on it. There is a risk of electric shock.
Handle the battery wearing insulated gloves.
• Do not step on the product or the product՚s packaging since the product may be
damaged.
• Do not place any foreign objects on top of the Battery Pack and on the cooling n.
• Do not put the battery pack upside down on the ground.
• Do not connect the power cables at terminal the block in the opposite direction.
• Do not charge or discharge a damaged battery.
• If the Product is installed in a garage or carport, ensure there is adequate clearance
from vehicles.
• The battery pack has been certied 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 or water sources, as they may cause:
- Power limitation phenomena in the battery (with a resulting decrease in energy
production by the system).
- Premature wear of the electrical/electromechanical and mechanical components.
- Reduction in performance, performance warranty and possible damage of the battery
• Only use the product with a LGES-authorized inverter.
For a list of compatible inverters, visit the LG ESS Battery Website by the URL
below and check the ‘Home Battery’ > ‘Product Info’ menu.

• Do not connect any AC conductors or photovoltaic conductors directly to the
battery pack. These are only to be connected to the inverter.
1.2.3 Response to Emergency Situations
The Product includes internal fault mechanisms designed to prevent failures and subsequent
risk hazards. However, LG Energy Solution cannot guarantee safety performance of the
Product is ever exposed to abuse, damage or negligence.
• If a user happens to be exposed to the internal materials of the battery cell due to
damage on the outer casing, the following actions are recommended.
In case of inhalation: Leave the contaminated area immediately and seek medical
attention.
In case of contact with eyes: Rinse eyes with running water for 15 minutes and
seek medical attention.
In case of contact with skin: Wash the contacted area with soap thoroughly and
seek medical attention.
In case of ingestion: Induce vomiting and seek medical attention.
If a re breaks out at the location where the battery pack is installed, perform the following
countermeasures.
• 
A respirator is not required during normal operation.
Use an FM-200 or CO2 extinguisher for battery res.
Use an ABC re extinguisher if the re is not from the battery and has not yet spread to it.

1. If a re occurs when charging batteries, provided it is safe to do so, disconnect
the battery pack circuit breaker to shut o the power charge.
2. If the battery pack is not on re yet, extinguish the re before the battery pack
catches re preferably with water.
3. If the battery pack is on re, do not try to extinguish it, and evacuate people
from the premises immediately.
WARNING
There may be a possible explosion when batteries are heated above 150°C. When a
battery pack is burning, it will leak poisonous gases. Do not approach it.
