FCC Compliance

This equipment has been tested and found to comply with the limits for a Class B digital

device, pursuant to part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in a residential installation. This

equipment generates, uses and can radiate radio frequency energy and, if not installed

and used in accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on,

you are encouraged to try to correct the interference by one or more of the following

measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and the receiver.

Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by the party responsible for

compliance may void the user’s authority to operate the equipment.

CONSIGNES DE SÉCURITÉ IMPORTANTES

CONSERVEZ CES INSTRUCTIONS

WARNING!

The inverter cover must be opened only after switching the inverter ON/OFF/P

switch located at the bottom of the inverter to OFF. 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.

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 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. This

product must be connected to a grounded, metal, permanent wiring system, or

an equipment-grounding conductor must be run with the circuit conductors

and connected to the equipment grounding terminal or lead on the product.

AVERTISSEMENT!

Avant d'utiliser l'onduleur monophasé, assurez-vous que l'onduleur est

correctement mis à la terre. Ce produit doit être raccordé à un système de

câblage fixe, métallique, l'équipement-le conducteur de mise à la terre doit être

exécuté avec les conducteurs de circuit et raccordé à l'équipement borne de

mise à la terre ou de plomb sur le produit.

WARNING!

Opening the inverter and repairing or testing under power must be performed

only by qualified service personnel familiar with this inverter.

AVERTISSEMENT!

L’unité ne doit être ouverte que par un technicien qualifié dans le cadre de

l'installation et de la maintenance.

WARNING!

The Safety Switch meets all requirements for a code-compliant installation of

this system. The DC Disconnect Switch disconnects both the positive and

negative conductors.

AVERTISSEMENT!

Le sectionneur externe (inclus) repond aux exigences de conformité pour

l’installation de ce système . Le coupeur CC ouvre les conducteurs positifs et

négatifs.

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!

Three phase 9,10, 20 kW inverter must be connected to a dedicated AC branch

circuit with a maximum Overcurrent Protection Device (OCPD) of 40A.

Three phase 14.4, 33.3 kW inverters must be connected only to a dedicated AC

branch circuit with a maximum Overcurrent Protection Device (OCPD) of 60A.

AVERTISSEMENT!

Les onduleurs triphasés 9,10,20 kW doivent être connectés à un branchement

AC dédié avec un disjoncteur de 40A.

L’onduleur triphasés 14.4, 33.3 kW doivent être connectés à un branchement AC

dédié avec un disjoncteur de 60A.
