CAUTION!
Danger due to poor or unprofessional installation.
This may result in damage to inverters and other live
photovoltaic system components.
Poor or unprofessional installation can cause overheat-
ing 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 ca-
bles:
► Tighten all terminals to the torque specified in the
Operating Instructions
► Tighten all grounding terminals (PE / GND), includ-
ing free ones, to the torque specified in the Operat-
ing 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! Fronius will not accept any costs associated with production downtimes, installer
costs, etc., that may arise as the result of a detected arc and its consequences. Fronius
accepts no liability for fires that can occur despite the presence of the integrated arc detec-
tion/extinguishing system (e.g. fires caused by a parallel arc).
Note! After an arc has been detected, the entire photovoltaic system must be checked for
possible damage before resetting the inverter.
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 tor-
ques to be used at the relevant terminal connections.
Proper use/in-
tended purpose
The inverter is intended exclusively to convert direct current from solar modules into alter-
nating current and to feed this into the public grid.
Utilisation not in accordance with the intended purpose comprises:
- Any use above and beyond this purpose
- Making any modifications to the inverter that have not been expressly approved by
Fronius
- the installation of components that are not distributed or expressly approved by Froni-
us.
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
Proper use also includes:
- Carefully reading and obeying all the instructions and all the safety and danger notices
in the Operating Instructions and Installation Instructions
- Performing all stipulated maintenance work
- Installation as specified in the Installation Instructions
