IMPORTANTINVERTERSAFETYINSTRUCTIONS

SAVETHESEINSTRUCTIONS

WARNING!

The inverter cover must be opened only after shutting off the inverter ON/OFF switch located at the

bottom of the Primary Unit, above the Connection Unit. This disables the DC voltage inside the inverter

and opens the AC relays. Wait five minutes before opening the cover. Otherwise, there is a risk of

electric shock from energy stored in the capacitors.

AVERTISSEMENT!

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.

HANDLING AND SAFETY INSTRUCTIONS

-Three Phase Inverter with Synergy Technology Installation MAN-01-00402-1.4

WARNING

Before operating the inverter, ensure that the inverter is grounded properly.

AVERTISSEMENT!

Avant d'utiliser l'onduleur monophasé, est correctement mis à la terre.

WARNING!

The inverter input and output circuits are isolated from the enclosure. This system does not include an

isolation transformer and should be installed with an ungrounded PV array in accordance with the

requirements of NEC Articles 690.35 and 690.43 National Electric Code, ANSI/NFPA 70, 2011 (and

Canadian Electrical Code, Part I, for installations in Canada).

Equipment grounding is the responsibility of the installer and must be performed in accordance with all

applicable Local and National Codes.

AVERTISSEMENT!

Les circuits d’entrée et de sortie de l’onduleur sont isolés de l’enveloppe. Ce système n’inclut pas

d’isolation galvanique (transformateur) et devra être installé sans mise à la terre du champ PV et en

accord avec les articles 690.35 et 690.43 du National Electric Code (NEC), ANSI/NFPA 70, 2011 (et du

Code Electrique Canadien, Partie 1, pour les installations faites au Canada).

La mise à la terre des équipements est la responsabilité de l’installateur et doit être faite en accord avec

les toutes les règles locales et nationales applicables.

WARNING!

Avant de faire ces étapes, éteignez l'onduleur monophasé en mettant sur OFF l'interrupteur ON/OFF

situé au bas de l'onduleur.

CAUTION!

Power optimisers are IP68/NEMA6P rated. Choose a mounting location where optimisers will not be

submerged in water.

Les optimiseurs de puissances sont compatibles à la norme IP68/NEMA6P. Choisissez le lieu de

montage tel que l’optimiseur ne puisse pas être submergé par l’eau.

CAUTION!

This unit must be operated according to the operating specifications provided with the unit.

Cette unité doit être opérée suivant les instructions trouvées dans le manuel fourni avec le produit.

CAUTION!

Cutting the power optimiser input or output cable connector is prohibited and will void the warranty.

Sectionner les cables d’entrées ou de sortie de l’optimiseur est interdit et annule sa garantie.

CAUTION!

All PV modules must be connected to a power optimiser.

Tous les modules doivent être connectés à un optimiseur de puissance.

CAUTION!

If you intend to mount the optimisers 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.

IMPORTANT SAFETY FEATURE

Modules with SolarEdge power optimisers are safe. They carry only a low safety voltage before the

inverter is turned ON. As long as the power optimisers are not connected to the inverter or the inverter is

turned OFF, each power optimiser will output a safe voltage of 1V.

Chapter 2: Installing the Power Optimisers

CAUTION!

Installing a SolarEdge system without ensuring compatibility of the module connectors with the

optimiser 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 optimisers’

connectors with the PV modules’ connectors to which they are connected:

lUse identical connectors from the same manufacturer and of the same type on both the power

optimisers and on the modules; or

lVerify that the connectors are compatible in the following way:

oThe module connector manufacturer should explicitly verify compatibility with the SolarEdge

optimiser connector; and

oA third-party test report by one of the listed external labs (TUV, VDE, Bureau Veritas UL, CSA,

InterTek) should be obtained, verifying the compatibility of the connectors.

ATTENTION!

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:.

lUtiliser des connecteurs identiques du même fabricant et du même type aussi bien pour les

optimiseurs de puissance que pour les modules.

lVérifiez que les connecteurs sont compatibles de la manière suivante:

oLe fabricant du connecteur doit explicitement vérifier la compatibilité avec le connecteur

SolarEdge.

oUn rapport de test de tierce partie doit être effectué par l’un des laboratoires externes indiqués ci-

dessous:(TUV, VDE, Bureau Veritas UL, CSA,Intertek), qui vérifiera la compatibilité des

connecteurs.

runs and necessary extensions between optimisers) should not exceed:

IMPORTANT SAFETY FEATURE

lFor a compliant PV Rapid Shutdown (PVRSS) installation, use no more than 30 optimisers per

string.

lEnabling PVRSS from the inverter menu is only required if the installed optimisers were

manufactured before 2015, otherwise it is enabled by default.

NOTE

The DC bus of each unit is separate and not shared for all units. Therefore in addition to following the

inverter design rules, each unit should follow the unit design rules as detailed in the Technical

Specifications.
