1.
Determinethepoweroptimizermountinglocationandusethepoweroptimizer
mountingbracketstoattachthepoweroptimizertothesupportstructure(See
Figure5).Itisrecommendedtomountthepoweroptimizerinalocationprotected
fromdirectsunlight.Forframe-mountedpoweroptimizersfollowtheinstructions
suppliedwiththeoptimizers,orreferto
https://www.solaredge.com/sites/default/files/installing_frame_mounted_power_
optimizers.pdf.
2.
Ifrequired,markthemountingholelocationsanddrillthehole.
CAUTION!
Donotdrillthroughthepoweroptimizerorthroughthemountingholes.Thedrillingvibrationscan
damagethepoweroptimizerandwillvoidthewarranty.
ATTENTION!
Ne pas percer à travers la optimiseur de puissance ou ses trous de fixation. Les vibrations qui en
résulteraient peuvent endommager la optimiseur de puissance.
3.
AttacheachpoweroptimizertotherackusingM6(1/4'')stainlesssteelbolts,nutsandwashersor
otherappropriatemountinghardware.Applytorqueof9.5N*m/7lb*ft.
For3NAseriespoweroptimizes,SolarEdgerecommendsmountingthepoweroptimizeronarailwith
thesmoothsidefacingout,sothatthepoweroptimizerbodywillpreventitsrotation.
4.
Usethefollowingmethods

togroundthepoweroptimizer:
WARNING!
Themetallicenclosureofthepoweroptimizermustbegroundedinaccordancewiththe
requirementsofthelocalandnationalcodes.
AVERTISSEMENT!
L'enceinte métallique de l’optimiseur de puissance doit être mise à la terre en accord avec les
régulations locales et nationales.
l For mounting on a grounded metal rail:Usetheprovided5/16''stainlesssteelgroundingstar
washerbetweentherailingandtheflatsideofthemountingbracket.Thegroundingwasher
shouldbreakthroughtheanodizecoatingoftherailingtoensurelowresistiveconnection.Apply
torqueof9.5N*m/7lb*ft.SeeFigure5.

Thesemethodshavebeenevaluatedbyanationallyrecognizedtestinglaboratoryaspartoftheoptimizerevaluation.
TheSolarEdge-suppliedgroundinglugkithasbeenevaluatedonlyforusewithSolarEdgepoweroptimizers.Itisnot
intendedorlistedtobeusedasageneralpurposegroundinglugwithotherelectricalequipment.
