Step 1: Mounting and Grounding the Power
Optimizers
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4).For
optimizerssuppliedwithmoduleframe-specificbrackets,attachthepoweroptimizerto
themoduleframefollowingtheinstructionsincludedwiththeoptimizers.
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.
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theM6(1/4'')stainlesssteelbolts,nuts
andwashers.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.
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.
