Dear Customer
First of all, we would like to thank you for purchasing LG Chem’s RESU high voltage battery.
We are consistently improving the product to enhance customer satisfaction, but we can
only
maintain the product quality with your help, too. As the installation volume grow, we are
finding
a growing number of reports related to the Auxiliary power switch.
This is a non-safety related problem, but it can affect the battery functionality.
Your caution is required in order to avoid the problem as the battery can be damaged.
Do not turn off the ‘Auxiliary power switch’ when the circuit breaker is in on position, as
follows.
1) Operation mode(Charging/Discharging)
2) F/W update mode
3) Beginning of the initialization
4) Commissioning
LG Chem has found that the power created from the Auxiliary switch when switched off can
damage the major parts in the DC/DC convertor, if the circuit breaker is in on position.
The current still exit the DC/DC converter even though inverter is turned off.
Please be aware that customers are allowed to turn off the power switch after moving the
circuit breaker to the off position.
Notify your LG Chem regional contact immediately when failed to do so or if you find
another
unfamiliar symptom.
Please be aware that the product can be used again after the repair by a certified
personnel from LG Chem. However, LG Chem cannot guarantee a defective product
caused
by the customer.
Sincerely yours,
Hyunchul Lyu
LG Chem ESS Customer service team leader

Battery Location Restrictions –Exposure to rain
The battery has an IP55 rating which means it’s tested to:
•Ingress of dust is not entirely prevented, but it must not enter Solid particle protection:
in sufficient quantity to interfere with the satisfactory operation of the equipment.
•Liquid ingress protection: Water projected by a nozzle (6.3 mm) against enclosure
from any direction shall have no harmful effects.
An IPX4 rating (liquid ingress protection against splashing) is generally considered
sufficient for rainfall as it protects against splashing from any direction. An IP55 rating
provides a greater level of protection.
The installation manual addresses water exposure in three places:
Page 6: "Do not expose or place near water sources like downspouts or sprinklers"
Page 7: "However, if installed outdoors, do not allow the battery back to be exposed to dir
ect sunlight and water sources as it may cause..."
Page 16: "The waterproof and properly ventilated area is recommended.
The page 6 reference identifies water sources as things like downspouts and sprinklers, it
ems that could subject the battery to sustained water flow. Rain fall isn’t a sustained stre
am of water and shouldn’t be considered a ‘water source.’
In addition, page 16 clarifies that a waterproof area is recommended, not required.

Illumination as required by NEC 706.10(E)
NEC 706.10(E) states:
Illumination. Illumination shall be provided for working spaces associated with ESS and their equipment and
components. Luminaires shall not be controlled by automatic means only. Additional luminaires shall not be required
where the work space is illuminated by an adjacent light source. The location of luminaires shall not do either of the
following:
(1) Expose personnel to energized system components while performing maintenance on the luminaires in the system
space
(2) Create a hazard to the system or system components upon failure of the luminaire
Existing illumination in a customer’s garage will satisfy this requirement:
“Luminaires shall not be controlled by automatic means only.”
This allows for automatic control so long as there is also manual control available. If the light is switched, it
should meet this requirement
“Additional luminaires shall not be required where the work space is illuminated by an adjacent light source.”
Per 210.70(A)(2)(1): "At least one wall switch–controlled lighting outlet shall be installed in hallways, stairways,
attached garages, and detached garages with electric power.”
A garage is required to have a switch controlled lighting outlet so illumination is available in the same space the battery
will be installed in.
In addition, the language in 706.10(E) mirrors 100.26(D):
Illumination. Illumination shall be provided for all working spaces about service equipment, switchboards, switchgear,
panelboards, or motor control centers installed indoors. Control by automatic means only shall not be permitted.
Additional lighting outlets shall not be required where the work space is illuminated by an adjacent light source or as
permitted by 210.70(A)(1), Exception No. 1, for switched receptacles.
Which suggests that the lighting currently accepted for other equipment associated with the solar installation (notably
the inverter) is also acceptable to meet the requirements of 706.10(E).
