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 service.
1.2.1 General Safety Precautions
Over-voltages or wrong wiring can damage the battery pack and cause

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

6
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).

• 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, go to :
https://www.lgessbattery.com/us (in case of North America)
https://www.lgessbattery.com/au (in case of Australia)
https://www.lgessbattery.com/eu (in case of all EU-countries in general)
https://www.lgessbattery.com/de (in case of Germany)
https://www.lgessbattery.com/it (in case of Italy)
https://www.lgessbattery.com/es (in case of Spain)
• 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 ES 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.
• Utilize re-extinguishing media
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.
• Follow proper re-ghting instructions
1) If a re occurs when charging batteries, provided it is safe to do so,
disconnect the battery pack circuit breaker to shut off 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.
