2.0 SafetyPrecautions
Beforeinstallingthisproduct,readallsafetyinstructionsinthisdocument.


 AllinstallationsmustbeperformedincompliancewiththeNationalElectrical
Code(NEC)andanyapplicablelocalcodes.
 ForCanadianjurisdictions,installationsshallbeinaccordancewithCSAC22.1,
SafetyStandardforElectricalInstallations,CanadianElectricalCode,Part1
 ModulescertifiedtoUL61730areSafetyClass2
forprotectionagainst
electricshock
 Therearenouser‐serviceablepartswithinthemodule.Donotattemptto
repairanypartofthemodule.
 Installationshouldbeperformedonlybyqualifiedpersonnel.
 Donotstandon,drop,scratch,orallowobjectstofallonmodulesasdoing
so
maydamagethemandvoidthewarranty.
 Donotplaceanythingonthemodules,evenforamomentbecauseresulting
residuemaydamageorstaintheglasssurface.
 Ifthefrontglassisbroken,orthebacksheetistorn,contactwithanymodule
surfaceormoduleframecan
causeelectricshock.
 BrokenJ‐boxesorconnectorsareelectricalhazardsaswellaslaceration
hazards.Installersshouldremoveanysuchmodulefromthearrayand
contactSunPowerfordisposalinstructions.
 Donotinstallorhandlethemoduleswhentheyarewetorduringperiodsof
highwind.
 Donotblockdrainholesorallowwatertopoolinornearmoduleframes.
 SunPowerrecommendsaconservativeminimumcablebendradiusofequal
toorgreaterthan
40mm(1.5”).
 Unconnectedconnectorsmustalwaysbeprotectedfrompollution(e.gdust,
humidity,foreignparticles,etc),priortoinstallation.Donotleave
unconnected(unprotected)connectorsexposedtotheenvironment.Aclean
assemblyenvironmentisthereforeessentialtoavoidperformance
degradation.
 Do not allow the connectors to come in
 contact with chemicals such as
greases,oilsandorganicsolventswhichmaycausestresscracking.
 Do not disconnect any modules when its inverter is feeding in to the grid.
Switchofftheinverterbeforedisconnecting,reinstallingormakinganyaction
withthemodules.
 Forconnectors, whichare accessible
tountrainedpeople,itisimperativeto
usethelockingconnectorsandsafetyclips,ifapplicable,inordertodefend
againstuntrainedpersonneldisconnectingthemodulesoncetheyhave been
installed.
 Cover all modules in the PV array with an opaque cloth or material before
makingorbreakingelectricalconne ctions.

 ContactSunPowerifmaintenanceisnecessary.
 Savetheseinstructions!

2.1FireRating
ThemodulefireratingisType2perUL1703,2013editionandClassCper
UL1703,2002edition.FireratingclassificationforanyPVsystemusing
UL1703:2013canonlyestablishafireratingincombinationwiththemounting
systemratingsnormallyfoundinthemountingsysteminstallationinstructions.
3.0 ElectricalCharacteristics
ElectricalcharacteristicsofthemodulesaredescribedinTable1below.Rated
electricalcharacteristicsarewithin10percentofmeasuredvaluesatStandard
TestConditionsof:1000W/m2,25°Ccelltemperatureandsolarspectral
irradianceperIEC60904‐3orirradiationof(airmass)AM1.5global(G)spectrum.
Eachmodule
containsthreebypassdiodes.Themaximumseriesfuserati ngis
15A;forA‐SeriesandM‐Seriesmodulesitis20A.
Undernormalconditions,aphotovoltaicmodulemayexperienceconditionsthat
producemorecurrentand/orvoltagethanreportedatStandardTestConditions.
Accordingly,thevaluesofISCandVOCmarked
onULListedmodulessh ould
alwaysbemultipliedbyafactorof1.25whendeterminingcomponentvoltage
ratings,conductorcapacities,fusesizesandsizeofcontrolsconnectedtothe
moduleoutput.RefertoSection690‐8oftheNECforanadditional1.25Safety
factorwhichmaybeapplicable.
DANGER!Moduleinterconnectioncablespassdirectcurrent(dc)and
aresourcesofvoltagewhenthemoduleisunderloadandwhenitis
exposedtolight.Directcurrentcanarcacrossgapsandmaycause
injuryordeathifimproperconnectionordisconnectionismade;or
ifcontactismadewithmoduleleadsthatarefrayedortorn.Donot
connectordisconnectmoduleswhenacurrentsourceisenergizing
theconductors.Modulesmaycontainhighvoltagewhen
interconnectedwithothermodules.
IMPORTANT!Pleasereadtheseinstructionsintheirentiretybefore
installing,wiring,orusingthisproductinanyway.Failuretocomply
withtheseinstructionswillinvalidatetheSunPowerLimited
WarrantyforPVModules.
