understood before performing any installation.
•Do not touch the solar module with bare hands.
After Installation
•Plug in the connector tightly and ensure that the wiring
properly works.
•Conduct periodic inspection of the panels for damage
to front glass, back sheet, frame, junction box, or
external electrical connections.
•Check electrical connections for loose connections

It may result in a burn or injury.
•Do not disassemble the solar module.
•After installation or repair, check that the solar module
are operating properly.
•In the event that the currently used solar module or
parts have been replaced the newly replaced module
and parts must have the same model name and parts
as the previously installed solar module.
•Do not let anyone approach the solar module who has
little knowledge of solar modules or on the measures to
take when solar modules are damaged in order to avoid
the risk of injury or electrical shock.
•Secure all necessary permits and licenses to install
the solar modules.
•Do not locate the solar module horizontally, as this may
cause dirt or white efflorescence(glass deformation).

•Do not work alone. Please work as part of a team of
two or more people.
•Safety harness use is strongly recommended for
installation.
•Partial shadowing may substantially reduce panel and
system output and may be the reason for the damage
of solar module.
•Care must be taken to avoid low tilt angles which may
cause dirt to buildup on the glass against the frame
edge.
•Dirt build-up on the surface of the panel may
cause active solar cells to be shaded and electrical
performance to be impaired.

•
Water, ethanol or a conventional glass cleanser with
rinsing of the front glass to remove dust, dirt or other
deposits.
Do not use ground water containing calcium carbonate
components when cleaning glass.
•Aggressive and abrasive cleansers or chemicals such
as alkali chemicals including ammonia based solution
should not be used on cleaning the module.
•Always keep the back surface of the panel free from
any foreign objects or structural elements which could
come into contact with the panel, especially when the
panel is under mechanical load.
•Deposits of foreign material on the frame surface can
be cleaned by using a wet sponge or cloth and dried
in air or by using a clean chamois.

Caution
•Avoid all electrical hazards when installing, wiring,
operating and maintaining all panels.
•Do not connect panels that have different electrical
system.
•Match the polarities of cables and terminals when
making the connections; failure to do so may result in
damage to the panel.
•When reverse currents can exceed the value marked
on the name plate, a properly rated and certified
over-current device(fuse or circuit breaker) must be
connected in series with each panel or string of panels.
•The rating of the over-current device shall not exceed
the maximum series fuse rating marked on the name
plate.
•The panel contains factory installed bypass diodes
located inside the junction box.
•When installing the system, it is recommended to
install a lightning rod to protect the system.
•The induced overvoltage by lightning can cause the
system damage, you should design conductor loop
connection as minimum as possible.
•The junction box should not be opened. Opening the
junction box will void the warranty.
•Panels with a suspected electrical problem should be
returned to LG Electronics for inspection and possible
repair or replacement as per the warranty conditions
provided by LG Electronics.
Electrical Connections
•Shock hazard may occur near the solar modules
electrical connections.
•Modules may be connected in series and/or parallel
to achieve the desired electrical output as long as it
sheet.
•Please use only the same type of modules in a
combined source circuit.
•Do not disconnect the module under when it is
operating. Shock hazard may occur near the solar
modules connection means.
•When the module installing in series or in parallel (e.g.
using for extension cables, etc.), the connector of each
original female or male connector of the same supplier)

Parallel Connection
•The solar modules may be combined in parallel to
produce the desired current output.
•When modules are combined in parallel, the total
current is equal to the sum of currents from each
module.
•The voltage of each module connected in parallel
should be the same.
•When connecting plural strings of modules in parallel
every series string or solar module must be fused prior
to combining with other strings.

for the protection of the module and cables from over-
current for prevention of unbalanced string voltage.
•A multiplying factor is required for increased output
of the PV modules. Under normal conditions, a PV
module is likely to experience conditions that produce
more current and/or voltage than reported at standard
test conditions. The requirements of the National
Electrical Code (NEC) in Article 690 shall be followed
to address these increased outputs. In installations
not under the requirements of the NEC, the values
of Isc and Voc marked on this PV module should
be multiplied by a factor of 125% when determining
component voltage ratings, conductor ampacities,
fuse sizes, and size of controls to the PV output.
•Depending on national directives, additional safety
factors might be applicable for over current protection.
Earth Grounding
•All work must be conducted in conformance with all
Federal, State, and local codes and standards.
•Grounding works should be performed by an
authorized installer for the safety and maintenance of
the system in accordance with all national, state and
local electrical codes and regulations and standards.
