Safety
WARNING! Incorrect operation or shoddy workmanship can cause serious injury or damage. Commis-
sioning of the inverter may only be carried out by trained personnel in accordance with the technical re-
gulations. It is essential that you read the "Safety Rules" chapter before commissioning the equipment
or carrying out maintenance work.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar modu-
les that are exposed to light.
- Make sure that both the AC side and the DC side of the inverter are de-energised before making
any connections.
- Only an authorised electrical engineer is permitted to connect this equipment to the public grid.
WARNING! An electric shock can be fatal. Danger of electric shock if the solar module is not grounded
or is not grounded properly.
To comply with IEC 62109-2:2011, any grounding required by the manufacturer of the solar module wi-
thin the inverter must only be carried out via the specified fuse.
WARNING! An electric shock can be fatal. Danger from DC voltage in solar modules. The inverter's in-
sulation monitoring is deactivated when the solar modules are grounded.
- Ensure that grounded solar modules are designed so that they are isolated according to Protection
Class II
- Place the relevant safety sticker in a clearly visible place on the photovoltaic system
- Configure the inverter so that an error message is displayed if the fuse trips..
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar modu-
les.
- The DC main switch is only to be used to de-energise the power stage set. The connection com-
partment is still live when the DC main switch is switched 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 from residual voltage in capacitors.
Wait for the capacitors to discharge. The discharge time is 3 minutes
WARNING! Inadequate PE conductor connections can cause serious injury and damage. The housing
screws provide a suitable PE conductor connection for earthing (grounding) the housing and must NOT
be replaced by any other screws which do not provide a reliable PE conductor connection.
CAUTION! Risk of damage to the inverter from dirt or water on the terminals and contacts of the connec-
tion area.
- When drilling, ensure that terminals and contacts in the connection area do not become dirty or wet.
- The wall bracket without power stage set does not conform to the protection class of the inverter as
a whole, and therefore must not be installed without the power stage set.
The wall 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 tigh-
tened terminals can cause heat damage 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 20 A.
- Connect the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, taking care to en-
sure that the polarity is correct.
