Allinstructionsandmechanicalandelectricalrequirementsshouldbereadandunderstoodbeforeattemptinginstallation.
Theinstallershouldconformtoallsafetyprecautionsinthisguidewheninstallingthemodule.
Limitation of Liability
Becausetheuseofthismanualandtheconditionsormethodsofinstallation,operation,useandmaintenanceofphotovoltaic(PV)productsarebeyond
SolarEdgecontrol,SolarEdgedoesnotacceptresponsibilityandexpresslydisclaimsliabilityforloss,damage,orexpensearisingoutoforinanywayconnected
withsuchinstallation,operation,useormaintenance.SolarEdgereservestherighttochangethemanualwithoutpriornotice.
Modulesratedforuseinthisapplicationclassmaybeusedinsystemsoperatingatgreaterthan50VDCor240W,wheregeneralcontactaccessisanticipated.
ModulesqualifiedforsafetythroughIEC61730-1andthispartofIEC61730withinthisapplicationclassareconsideredtomeettherequirementsforsafetyclass

Chapter 2: Mechanical Installation
Installation Consideration and Environmental Conditions
InstallSolarEdgemodulesatsitesthatmeetthefollowingrequirements:
lEnvironmenttemperature:-40to85°C
lOperatingtemperature:-40to85°C
lMaximumaltitudethemoduleisdesignedfor:2000m
lMechanicalloadonmodules(e.g.,fromwindorsnow):frontdesignloadislessthan3600Paandreartestloadislessthan2400Pa(safetyfactorof1.5).
lTomaintainthemodules’ClassCfirerating,thefireclassoftheroofandbuildingmaterialsshouldhigherthanClassC.Thefiresafetyratingofthismoduleis
validonlywhenmountedinthemannerspecifiedinthemechanicalmountinginstructions.
lDonotinstallmodulesatlocationsthatcomewithdirectcontactofwater,saltwateroranyaggressiveenvironmentalcondition.
lDonotinstallthemodulesnearflamesorflammablematerialsorlocationswithhazardousmaterials.
Installation Methods
Clamping
Modulescanbelaideitheracrossthesupportingrails(Figure 1)orparalleltothem(Chapter 2andFigure 2).


Figure 1: Clumping modules onto the frame with aluminum clamps across the supporting rails

Figure 2: Clumping modules onto the frame with aluminum clamps parallel to the supporting rails
EachaluminummountingclampcomeswithanM8bolt,aplainwasher,aspringwasher,andanM8nut.
NOTE
Makesuretouseclampswiththefollowingproperties:
Thedimensionsforthemiddleclampsarea≥40mm,b≥26mm,c=8mm,d≥28mm,andØ=9mm.
Therecommendedtorquefortighteningthenutandboltsis28N*MwhenthepropertyclassofboltsandnutsisClass8.8.
Tofastenthemodule:
1. Placethemoduleonthetwosupportingrails(notprovided).Therailsshouldbemadewithstainlessmaterialortreatedwithananti-corrosionprocess
(e.g.,anodicoxidationtreatment).
2. Therail’stopsurfacecontactedwithmoduleframeshouldcomewithgroovescompatiblewithanM8bolt.
3. Iftherailsdonotcomewithgrooves,holesofasuitablediametermayneedtobedrilledtoallowboltstobeattachedtotherailsatthesamelocationsas
mentionedbefore.
4. Secureeachclampbyattachingplainwasher,springwasher,andnut,inthatorder.
5. Bothofclose-upsofFigure 3indicatethemiddleclampsandSeeFigure 4indicatethesideclampsforyourreference.

lThemaximumsystemvoltageoftheSolarEdgemodulesis1000V.
lThepoweroptimizersregulatethestringvoltageataconstantlevel,regardlessofstringlengthandenvironmentalconditions.
lUndernormalconditions,amodulemightproducemorecurrentand/orvoltagethanreportedatstandardtestconditions1.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moduleshouldbemultipliedbyafactorof1.25whendeterminingcomponentvoltageratings,conductorcapacities,
overcurrentdeviceratings,andsizeofcontrolsconnectedtothePVoutput.
lEachseries-connected,stringofmodulesshallbeprovidedwiththemaximumseriesovercurrentprotectivedevice,specifiedas15Aforthe6inchcell
