WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar modules that are exposed to light.
– Ensure that both the AC side and the DC side of the inverter are de-energised before carrying out any connection work.
– Only an authorised electrical engineer is permitted to connect this equipment to the public grid.
– The DC main switch is only to be used to de-energise the power stage set. The connection area is still live when the DC main switch is swit-
ched off.
– Ensure that the power stage set and connection area are disconnected from one another before carrying out any maintenance or service
tasks.
– The power stage set, which is enclosed in a separate housing, must only be disconnected from the connection area when in a de-energized
state.
– Maintenance and servicing in the power stage set of the inverter must only be carried out by Fronius-trained service technicians.
WARNING! An electric shock can be fatal. Danger due to residual voltage in capacitors. Wait for the capacitors to discharge. The discharge
time is five minutes.
WARNING! An inadequate ground conductor connection can cause serious injury or damage. The housing screws provide a suitable ground
conductor connection for grounding the housing and must NOT be replaced by any other screws that do not provide a reliable ground conduc-
tor connection.
CAUTION! Risk of damage to the inverter from dirt or water on the terminals and contacts of
the connection area.
– When drilling, ensure that terminals and contacts in the connection area do not become dirty or wet.
– Without a power stage set, the mounting bracket does not conform to the protection class of the inverter as a whole and so must not be
installed without the power stage set.
– The mounting bracket should be protected from dirt and moisture during installation.
CAUTION! Risk of damage to the inverter as the result of incorrectly tightened terminals. Incorrectly tightened terminals can cause heat da-
mage to the inverter that may result in a fire. When connecting AC and DC cables, ensure that all the terminals are tightened to the specified
torque.
CAUTION! Risk of damage to inverter from overload.
– The maximum amperage when connecting to a single DC terminal is 36 A.
– Connect the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, taking care to ensure that the polarity is correct.
CAUTION! Risk of damage to inverters and other live photovoltaic system components due to poor or unprofessional installation. Poor or
unprofessional installation can cause overheating of cables and terminal connections and result in arcs. These can cause heat damage, which in
turn may lead to fires.
Observe the following when connecting AC and DC cables:
– Tighten all terminals to the torque specified in the Operating Instructions
– Tighten all grounding terminals (PE / GND), including free ones, to the torque specified in the Operating Instructions
– Do not overload cables
– Check cables for damage and verify that they are laid correctly
– Take note of the safety instructions, Operating Instructions and any local connection regulations
Using fastening screws, always screw the inverter firmly to the mounting bracket to the torque
specified in the Operating Instructions. Ensure that the fastening screws are tight before starting the inverter!
NOTE! Ensure the polarity is correct when connecting the DC cables.
NOTE! Degree of protection IP 65 is only applicable if
– the inverter is placed in the mounting bracket and permanently attached using screws
– the cover for the data communication area is permanently attached to the inverter with screws
Degree of protection IP 20 applies to the mounting bracket with no inverter.
NOTE! When connecting aluminium cables:
– Observe national and international guidelines regarding the connection of aluminium cables
– Follow the instructions of the cable manufacturer
– Check every year that the cables are securely attached in accordance with the specified torque
NOTE! For grounding solar module frames or racks, the relevant specifications from the solar module manufacturer must be taken into account
along with national guidelines.
NOTE! Observe the ESD guidelines when using option cards.
NOTE! If the inverter is installed in Australia or New Zealand (required standard: AS4777.2:2020), the inverter must not be used as part of a
three-phase combination, as there is no communication link between the inverters
Observe the manufacturer's connection, Installation and Operating Instructions at all times. To reduce the hazard potential to a minimum,
perform all installation and connection work carefully according to the instructions and regulations. Refer to the device Operating Instructions
/ Installation Instructions for the tightening torques to be used at the relevant terminal connections.
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 ! Les mod-
ules solaires exposés à la lumière fournissent la tension à l'onduleur. Ce document ne décrit pas toutes les possibilités de configurations sys-
tème. Le soussigné, Fronius International GmbH, déclare que l'équipement radioélectrique du type Fronius Primo est conforme à la directive
2014/53/UE. Le texte complet de la déclaration UE de conformité est disponible à l'adresse internet suivante: www.fronius.com
AVERTISSEMENT ! Une décharge électrique peut être mortelle. Danger en raison de la tension du secteur et de la tension DC des modules
solaires exposés à la lumière.
– Avant toute opération de raccordement, veiller à ce que les côtés AC et DC en amont de l'onduleur soient hors tension.
– Le raccordement fixe au réseau électrique public doit être réalisé uniquement par un électricien agréé.
– L'interrupteur principal DC sert exclusivement à la mise hors courant de l'étage de puissance. Lorsque l'interrupteur principal DC est dé-
connecté, la zone de raccordement reste sous tension.
– Les opérations de maintenance et de service doivent être exécutées uniquement lorsque l'étage de puissance et la zone de raccordement
sont séparés.
– Le bloc indépendant de l'étage de puissance ne doit être séparé de la zone de raccordement que si l'ensemble est hors tension.
– Les opérations de maintenance et de service dans l'étage de puissance de l'onduleur doivent être exécutées uniquement par du personnel de
service formé par Fronius.
