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, ensure 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 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause interference;
and (2) 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 < 30 VDC / 8 A / 240 VA and <
15 VAC / 8 A / 240 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 <
30 VDC / 8 A / 240 VA and < 15 VAC / 8 A / 240 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:
https://manuals.fronius.com/html/4204260312/#0_m_0000018823
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 2023 Art. 690.12 and Canadian Electrical Code CSA
C22.1:21 Art. 64-218. The PLC is implemented according to the specification
“Communication Signal for Rapid Shutdown SunSpec Interoperability
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 errors. 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.
