EN: WARNING!
Operating the equipment incorrectly or poor workmanship can cause serious injury or damage. The inverter may only be installed
and commissioned by trained personnel acting in accordance with the technical regulations. Before working with the device, en-
sure that you have read and understand all the documents provided (both hard copies enclosed with the product and documents
provided online).
FR: AVERTISSEMENT!
Les erreurs de commande et les erreurs en cours d’opération peuvent entraîner des dommages corporels
et matériels graves. L’installation et la mise en service de l’onduleur ne doivent être effectuées que par du personnel formé à cet effet et
dans le cadre des dispositions techniques. Ne travailler avec l’appareil que lorsque tous les documents mis à disposition en annexe, imprimés
et en ligne, ont été lus et compris !
ES-MX: ADVERTENCIA!
El manejo incorrecto y los trabajos realizados de forma incorrecta pueden provocar daños personales o materiales
graves. La instalación y la puesta en marcha del inversor deben llevarse a cabo exclusivamente por personal formado y en el marco de
las disposiciones técnicas. ¡Antes de trabajar con el equipo, leer y comprender todos los documentos adjuntos y puestos a disposición en
línea!
FCC
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part of the FCC Rules. Opera-
tion is subject to the following two conditions:
() This device may not cause interference; and
() This device must accept any interference, including interference that may cause undesired operation of the device.
Rapid Shutdown
Two different types of rapid shutdown (RSD) can be triggered depending on the configuration and on-site installation:
Via external buttons: One or more external buttons can be installed on the WSD (wired shutdown) interface of the Data communication area
on page (→). Pressing one of these buttons triggers the rapid shutdown. The terminals are discharged to < VDC / A / VA and < VAC
/ A / VA. The inverter also interrupts the communication to the shutdown devices of the PV modules if they correspond to the SunSpec
standard for rapid shutdown.
Via the loss of the grid connection: An automatic rapid shutdown can also occur if the grid connection is lost. The inverter identifies a failure of
the grid connection and terminals are discharged to < VDC / A / VA and
< VAC / A / VA. The inverter also interrupts the communication to the shutdown devices of the PV modules if they correspond to the
SunSpec standard for rapid shutdown.
For more information see
Power Line Communication (PLC) transmitter
The inverter is equipped with a Power Line Communication (PLC) transmitter on the DC side.
Its function is to ensure rapid shutdown in accordance with National Electric Code NEC Art. . and Canadian Electrical Code CSA
C.: Art. -. The PLC is implemented according to the specification “Communication Signal for Rapid Shutdown – SunSpec Interop-
erability Specification”. Please visit www.sunspec.org for details.
AFCI - Arc Fault Circuit Interrupter (Arc Guard)
An AFCI (arc fault circuit interrupter) protects against arc faults and, in the narrower sense, is a protection device in the event of contact er-
rors. The AFCI evaluates faults that occur in the current and voltage flow on the DC side using an electronic circuit and shuts down the circuit
if a contact error is detected. This prevents overheating at poor contact points and, ideally, possible fires.
DANGER
Danger from faulty or incorrect DC installation.
This may result in a risk of damage and, as a consequence, risk of fire in the PV system due to prohibited thermal loads that occur during an
arc.
► Check the plug connections to ensure that they are correct.
► Repair faulty insulation correctly.
► Perform connection work in line with the instructions.
