1. Determinethepoweroptimisermountinglocationandusethepoweroptimiser
mountingbracketstoattachthepoweroptimisertothesupportstructure(See
Figure5).Itisrecommendedtomountthepoweroptimiserinalocationprotected
fromdirectsunlight.Forframe-mountedpoweroptimisersfollowtheinstructions
suppliedwiththeoptimisers,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!
Drilling vibrations may damage the power optimiser and will void the warranty. Use a torque wrench
or an electric drill with adjustable clutch that meets the mounting torque requirements. Do not use
impact drivers for mounting the power optimiser.
Do not drill through the power optimiser or through the mounting holes.
ATTENTION!
Les vibrations résultant du perçage peuvent endommager l’optimiseur de puissance et annulera la
garantie. Utilisez une clé dynamométrique ou une perceuse électrique avec embrayage adaptable
compatible avec les moments indiqués. Ne pas utiliser des tournevis à percussion pour fixer
l’optimiseur. Ne pas percer à travers l’optimiseur de puissance ou ses trous de fixation.
3.
AttacheachpoweroptimisertotherackusingM6(1/4'')stainlesssteelbolts,nutsandwashersor
otherappropriatemountinghardware.Applytorqueof9-10N*m/6.5-7lb*ft.
For3NAseriespoweroptimizes,SolarEdgerecommendsmountingthepoweroptimiseronarailwith
thesmoothsidefacingout,sothatthepoweroptimiserbodywillpreventitsrotation.
4.
Usethefollowingmethods
1
togroundthepoweroptimizer:
WARNING!
The metallic enclosure of the power optimiser 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 optimiser 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.
