
Pour installation à même le module ou la monture du module, consultez d'abord le fabricant du module
sur la position et son impact sur la garantie du module. Le perçage de trous dans le cadre du module
devra se faire suivant les instructions du fabricant.
CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module connectors with the
optimizer connectors may be unsafe and could cause functionality problems such as ground faults,
resulting in inverter shut down. In order to ensure mechanical compatibility of the SolarEdge optimizers
and the modules to which they are connected, use identical connectors from the same manufacturer
and of the same type on both the power optimizers and on the modules.

Les connecteurs du module doivent être mécaniquement compatibles avec les optimiseurs de
puissance. Sinon, le système SolarEdge installé peut être dangereux ou causer des problèmes
fonctionnels, tels que les défauts de terre, qui peuvent provoquer un arrêt de l’onduleur. Afin d'assurer la
compatibilité mécanique entre les optimiseurs de puissance SolarEdge et les modules auxquels ils sont
connectés, il faut Utiliser des connecteurs identiques du même fabricant et du même type aussi bien
pour les optimiseurs de puissance que pour les modules.

IMPORTANTSAFETYFEATURE
Modules with SolarEdge power optimizers are safe. They carry only a low safety voltage before the
inverter is turned ON. As long as the power optimizers are not connected to the inverter or the inverter is
turned OFF, each power optimizer will output a safe voltage of 1V.

Step 1: Mounting and Grounding the Power
Optimizers
Foreachofthepoweroptimizers1:
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2).Forframe-mountedpower
optimizersfollowtheinstructionssupplied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methods2togroundthepoweroptimizer3:
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.
