The manufacturer's specifications for connection, installation and operation must be ob-
served. You must carefully follow all installation steps and make all connections in accor-
dance with specifications and regulations to minimize any risk of danger.
The tightening torques for the respective terminals are listed in the operating instructions/
installation instructions for the devices.
Intended Use The solar inverter is designed exclusively to convert direct current from solar modules into
alternating current and feed this power into the public grid.
The following are deemed not to be in conformity with its intended purpose:
- utilization for any other purpose, or in any other manner
- alterations to the inverter that are not expressly recommended by Fronius
- installation of components that are not expressly recommended or sold by Fronius.
The manufacturer is not responsible for any damage resulting from improper use.
All warranty claims are considered void in such cases.
Proper use also means
- carefully reading and obeying all the instructions and safety and danger notices in the
operating instructions
- carrying out all the specified inspection and servicing work
- installation as per operating instructions.
When configuring the photovoltaic system, make sure that all photovoltaic system compo-
nents are operating completely within their permitted operating range.
All measures recommended by the solar module manufacturer for maintaining solar mod-
ule properties must be followed.
Utility company regulations regarding grid power feed must be followed.
Location Selec-
tion
Please note the following criteria when choosing a location for the inverter:
- Securely tighten all grounding terminals
(PE/GND) using the proper torque listed
in the operating instructions, even for
free grounding terminals.
- Do not overload cables.
- Check cables for damage and correct
wiring.
- Follow all safety instructions, operating
instructions, and any local connection
regulations.
Always secure the inverter to the wall bracket
with fixing screws using the torque specified
in the operating instructions.
Only put the inverter into operation with the
fixing screws securely tightened.
NOTE! Fronius will not bear any costs for production downtimes, or for installa-
tions, etc., which may arise due to a detected electric arc and its consequences.
Fronius accepts no liability for fires which may break out despite integrated arc
detection/interruption (e.g., due to a parallel arc).
NOTE! Before an inverter can be reset following a detected electric arc, check the
entire affected photovoltaic system for any damage.
