RISK OF ELECTRIC SHOCK AND FIRE. Use this inverter only with PV modules with a maximum
system voltage rating of 600V or higher.
RISQUE DE CHOC ELECTRIQUE ET D’INCENDIE. Utilisez cet onduleur seulement avec des
modules PV spécifiés pour une tension de système maximum de 600V ou plus.
WARNING!
The inverter cover must be opened only after shutting off the inverter ON/OFF switch located at the
bottom of the inverter. This disables the DC voltage inside the inverter. Wait five minutes before
opening the cover. Otherwise, there is a risk of electric shock from energy stored in the capacitors.
Ne pas ouvrir le couvercle de l'onduleur avant d'avoir coupé l'interrupteur situé en dessous de l'onduleur.
Cela supprime les tensions CC et CA de l'onduleur. Attendre que le LCD affiche une tension sécurisée
(50V). Si l’affichage LCD n’est pas visible, attendre cinq minutes avant d’ouvrir le couvercle. Sinon, il y a
un risque de choc électrique provenant de l'énergie stockée dans le condensateur.
WARNING
Before operating the inverter, ensure that the inverter is grounded properly.
Avant d'utiliser l'onduleur monophasé, assurez-vous que l'onduleur est correctement mis à la terre.

If you intend to mount the optimizers directly to the module or module frame, first consult the module
manufacturer for guidance regarding the mounting location and the impact, if any, on module warranty.
Drilling holes in the module frame should be done according to the module manufacturer instructions.

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. To ensure mechanical compatibility of the SolarEdge optimizers’
connectors with the PV modules’ connectors 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 PV 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.
