WARNING! Incorrect operation or poorly executed work can cause serious injury or damage. Commis-
sioning of the hybrid system may only be carried out by trained personnel in accordance with the techni-
cal regulations. Read the installation and operating instructions before installing and commissioning the
equipment.
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 carrying
out any connection work.
- Only an authorised electrical engineer is permitted to connect this equipment to the public grid.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar modu-
les or battery.
- 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 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 is only to be disconnected from the wall bracket once it is de-energised.
- 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 ca-
pacitors to discharge. The discharge time is 5 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 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.
- 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 set.
The wall bracket should be protected from dirt and moisture during installation.
CAUTION! Risk of damage to the inverter as a result of incorrectly tightened terminals. Incorrectly tigh-
tened terminals can cause heat damage to the inverter and, in turn, lead to 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 32 A.
- When connecting the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, take care
to ensure that the polarity is correct.
- The maximum DC input voltage must not exceed 1000 V DC.
NOTE! Protection class IP65 is only applicable if the inverter is permanently attached to the wall bra-
cket with screws.
Protection class IP20 applies to the wall bracket with no inverter.
NOTE! The solar modules connected to the inverter must conform to the Class A requirements of the
IEC 61730 standard.
NOTE! When photovoltaic modules are exposed to light, they supply current to the inverter.
IMPORTANT! Please refer to the leaflet "Installation and commissioning information sheet" (42,0410,1962).
