Fronius manufac-
turer's warranty
Detailed, country-specific warranty terms are available on the internet:

tem, please register at: www.solarweb.com.
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 mounting bracket does not conform to the protection class of the in-
verter as a whole and so must not be installed without the power stage set.
The mounting 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.
- Fronius Symo: The maximum amperage when connecting to a single DC terminal is 33 A.
- Fronius Eco: The maximum amperage when connecting to a single DC terminal is 15 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.
- The maximum DC input voltage must not exceed 1000 V DC.
NOTE! Degree of protection IP 66 is only applicable if:
- The inverter is placed in the mounting bracket and permanently attached using screws
- The cover for the data communication area is permanently attached to the inverter with screws
Protection class IP20 applies to the mounting bracket with no inverter and venting duct!
NOTE! The solar modules connected to the inverter must comply with the IEC 61730 Class A standard.
NOTE! When photovoltaic modules are exposed to light they supply current to the inverter.
NOTE!
- Ensure that the grid neutral conductor is grounded. This may not be the case for IT grids (insulated
grids with no grounding); it will then not be possible to use the inverter.
- In order to use the inverter, the neutral conductor must be connected.
A neutral conductor that is too small may adversely affect the inverter feeding energy into the grid.
The neutral conductor must therefore be the same size as the other live conductors.
Observe the manufacturer's connection, Installation and Operating Instructions at all times. To reduce the ha-
zard 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 torques to
be used at the relevant terminal connections.
