Safety Eσ
WARσIσύΞ Incorrect operation or poorly executed work can cause serious injury or damageέ ωommisά
sioning of the inverter may only be carried out by trained personnel in accordance with the technical reά
gulationsέ You should read the safety rules before commissioning the equipment or carrying out
maintenance workέ
WARσIσύΞ χn 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
WARσIσύΞ χn electric shock can be fatalέ ϊanger due to grid voltage and ϊω voltage from solar moduά
lesέ
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, which is enclosed in a separate housing, must only be disconnected from the
connection area when in a deάenergized stateέ
ά εaintenance and servicing in the power stage set of the inverter must only be carried out by όroniusά
trained service techniciansέ
WARσIσύΞ χn 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
WARσIσύΞ χn 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
CAUTIτσΞ Risk 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 wall bracket does not conform to the protection class of the inverter
as a whole and so must not be installed without the power stage setέ
The wall bracket should be protected from dirt and moisture during installationέ
CAUTIτσΞ Risk of damage to the inverter as a result of incorrectly tightened terminalsέ Incorrectly tighά
tened terminals can cause heat damage to the inverter and, in turn, lead to a fireέ When connecting χω
and ϊω cables, ensure that all the terminals are tightened to the specified torqueέ
CAUTIτσΞ Risk 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
στTEΞ Protection class IPθη is only applicable if the inverter is permanently attached to the wall braά
cket with screwsέ
Protection class IPβί applies to the wall bracket with no inverterέ
στTEΞ The solar modules connected to the inverter must conform to the ωlass χ requirements of the
IEω θ1ιγί standardέ
στTEΞ When photovoltaic modules are exposed to light, they supply current to the inverterέ
