Fronius Symo Hybrid Installation Seite 5

SafetyΝEσ
WARσIσύΞΝIncorrect operation or poorly executed work can cause serious injury or damageέ ωommisά
sioning of the hybrid system may only be carried out by trained personnel in accordance with the techniά
cal regulationsέ Read the Installation and τperating Instructions of the όronius Symo ώybrid and of the
battery before installing and commissioning the equipmentέ
WARσIσύΞΝχn electric shock can be fatalέ ϊanger due to grid voltage and ϊω voltage from solar moduά
les that are exposed to lightέ
ά Ensure that both the χω side and the ϊω side of the inverter are deάenergised before carrying out
any connection workέ
ά τnly an authorised electrical engineer is permitted to connect this equipment to the public gridέ
WARσIσύΞΝχn electric shock can be fatalέ ϊanger due to grid voltage and ϊω voltage from solar moduά
les or batteryέ
ά The ϊω main switch is only to be used to deάenergise the power stage setέ The connection area is
still live when the ϊω main switch is switched offέ
ά Ensure that the power stage set and connection area are disconnected from one another before
carrying out any maintenance or service tasksέ
ά The power stage set is only to be disconnected from the mounting bracket once it is deάenergisedέ
ά εaintenance and servicing in the power stage set of the inverter must only be carried out by όroniusά
trained service techniciansέ
ά ωheck that the battery is deάenergisedέ
WARσIσύΞΝχn electric shock can be fatalέ ϊanger due to residual voltage in capacitorsέ Wait for the caά
pacitors to dischargeέ The discharge time is five minutesέ
WARσIσύΞΝχn inadequate ground conductor connection can cause serious injury or damageέ The
housing screws provide a suitable ground conductor connection for grounding the housing and must
στT be replaced by any other screws that do not provide a reliable ground conductor connectionέ
CAUTIτσΞΝRisk of damage to the inverter from dirt or water on the terminals and contacts of the connecά
tion areaέ
ά When drilling, ensure that terminals and contacts in the connection area do not become dirty or wetέ
ά Without a power stage set, the mounting bracket does not conform to the protection class of the inά
verter as a whole and so must not be installed without the power stage setέ
The mounting bracket should be protected from dirt and moisture during installationέ
CAUTIτσΞΝRisk of damage to the inverter as the result of incorrectly tightened terminalsέ Incorrectly tighά
tened terminals can cause heat damage to the inverter that may result in a fireέ When connecting χω
and ϊω cables, ensure that all the terminals are tightened to the specified torqueέ
CAUTIτσΞΝRisk of damage to inverter from overloadέ
ά The maximum amperage when connecting to a single ϊω terminal is γβ χέ
ά ωonnect the ϊω+ and ϊωά cables to the ϊω+ and ϊωά terminals on the inverter, taking care to enά
sure that the polarity is correctέ
ά The maximum ϊω input voltage must not exceed 1ίίί V ϊωέ
στTEΞΝϊegree of protection IP θη of the inverter is only applicable if
ά the inverter is placed in the mounting bracket and permanently attached using screws
ά the cover for the data communication area is permanently attached to the inverter with screwsέ
ϊegree of protection IP βί applies to the mounting bracket with no inverterέ
στTEΞΝThe solar modules connected to the inverter must comply with the IEω θ1ιγί ωlass χ standardέ
στTEΞΝWhen photovoltaic modules are exposed to light they supply current to the inverterέ
