ELECTRICAL INSTALLATION
Caution
•Avoid allelectricalhazardswheninstalling, wiring,
operating andmaintaining allpanels.
•Do not connect panelsthat havedifferent electrical
properties or physicalconfigurations in the same sy
stem.
•Match the polarities of cables andterminalswhen ma
king the connections; failure to do so may result in da
mageto the panel.
•When reverse currents can exceedthe value marked
on the nameplate, aproperly rated andcertified over
-current device(fuse or circuit breaker) must be
connected in series with eachpanel or string of panels.
•The rating of the over-currentdeviceshall notexceed
the maximum series fuse rating marked on the name
plate.
•The panelcontains factory installed bypassdiodes
located inside the junction box.
•When installing the system, it isrecommended to
install a lightning rod to protect the system.
•The inducedovervoltage by lightning can cause the
system damage,you should designconductor loop
connection as minimum as possible.
•The junction boxshould not be opened. Opening the
junction boxwillvoid the warranty.
•Panels with asuspected electricalproblemshould be
returned to LG Electronics for inspection andpossible
repair or replacement as per the warrantyconditions p
rovided by LG Electronics.
Electrical Connections
•Shock hazardmay occur near the solar modules
electricalconnections.
•Modules may be connected in series and/or parallel
to achievethe desiredelectricaloutput as long as it i
swithin the guidelines on the product specification s
heet.
•Please useonly the same type of modules in a
combined source circuit.
•Do not disconnect the module under whenit is op
erating. Shock hazardmay occur near the solar m
odules connection means.
•When the module installing in series or inparallel(e.g.
usingfor extensioncables, etc.), the connectorof each
module should be the same products. (mated with its or
iginalfemale or male connector of the same supplier)
Diodes
•All LGmodules are equippedwith factory installedb
ypassdiodes. The factory-installed diodesprovide p
roper circuit protection for the module from unexpec
tedshadows.
Series Connection
•The solar modules may be wired in series to produce
the desiredvoltage output.
•The current of eachmodule connected in series
should be the same.
•The maximum number of series connected modules
can be determined by basis on maximum system volt
age, the 125%safety factor, andthe module Voc whi
ch can be checked in “Product Specifications” in this
document.
•The maximum solar module configuration can be
found in “Product Specifications”.

Parallel Connection
•The solar modules may be combined in parallelto
producethe desiredcurrent output.
•When modules are combined in parallel,the total
current is equalto the sum of currents from each
module.
•The voltage of eachmodule connected in parallel
should be the same.
•When connecting pluralstrings of modules in parallel e
very series string or solar module must be fused prior t
ocombining with other strings.
•Abide with allapplicable federal, state, andlocalcodes
for additionalfusing requirements andlimitations on the
maximum number of solar modules in parallel.
•Maximum series fuse rating is refer to “Product
Specifications; page11”.
•Parallel configuration is notlimited if propermeasures
are taken to blockthe reverse current flow, e.g. fuses f
or the protection of the module andcables from over-
current for prevention of unbalancedstring voltage.
•LG Electronics recommends to take blocking diode
for prevention of unbalanced string voltage.
•The reverse current flow in the string may be caused by
amoduleshortcircuit,incorrectwiring,shadow,etc.
•Blocking diodes must have :
1) VRRM(Repetitive Peak Reverse Voltage) :
1.5times of maximum system voltage
2) IF (Average Forward Current) :
2times of Isc (PV module short circuit current)
※It is selected in consideration of the thermal
characteristics of the diode, and it is recommended
to use acomponent of 30mA or less for IRRM
(Repetitive Peak Reverse Current, max).
•Amultiplying factor is required for increasedoutput
of the PV modules. Under normalconditions, aPV
module is likely to experienceconditions that produce
more current and/or voltage than reported at standard
test conditions. The requirements of the National Elect
rical Code(NEC) in Article 690shall be followed to ad
dressthese increasedoutputs.
The values of Isc andVoc marked on this PV module
should be multiplied by a factor of 125%when determ
iningcomponent voltage ratings, conductor ampacitie
s, fuse sizes, andsize of controls to the PV output.
•Depending on nationaldirectives, additionalsafety fact
ors might be applicable for over current protection.

General Wiring
•LGElectronics recommends that allwiring be double
insulated with aminimum rating of 90°C(194°F).
•All wiring should useaflexible copper (Cu) conductor.
•The minimum size should be determined by the
applicable codes.
•LGElectronics recommends asize no smallerthan
4mm2.
Earth Grounding
•All workmust be conducted in conformance with all
Federal, State, andlocalcodes andstandards.
•Grounding worksshould be performed by an authoriz
ed installer for the safety andmaintenance of the syst
em in accordancewith allnational, state and localele
ctricalcodes andregulations andstandards.
•Specific information on the solar module dimensions a
nd location of groundingholes is provided in “Product S
pecifications”.
•One M4 stainless steel bolt, onenut, onespring wash
er, two flat washers, onecup washer, onestar washe
r and 12 AWG Cu wiresare recommended per mount
ing hole.
•Where common groundinghardware(nut, bolts, washe
rs) isusedto attach alisted groundingdevice, the attac
hment must be made in conformance with the groundi
ng devicemanufacturer’s instructions.
•All hardwareshould be consist of corrosion resistant
material such as stainless steel.
•There is an earth hole on the edge of the module f
rame. Usingthis hole, an earth conductor andthe
solar module frame may be recommended to be c
onnected andearthed as the belowdrawing.
•All screws andnutsshall be tightened to atorque of
4~5 N∙m.
•To prevent electric shock andfire, aprotective ground must
be done on the frames of solar modules andarrays althoug
hthe solar modules from LGmeet the conditions of safety
class II. The nationaldirectives must be respected.
•Bonding points to groundshould be tight, secure andfree fro
