Fronius accepts no liability for fires that can occur despite the pres- ence of the integrated arc detection/extinguishing system (e.g. fires caused by a parallel arc). -
Page 7: Explanation Of Symbols And Choice Of Location
Proper use also includes carefully reading and obeying all the instructions and all the safety and danger notices in the operating instructions performing all stipulated inspection and maintenance work installation as specified in the operating instructions When designing the photovoltaic system, ensure that all of its components are operated within their permitted operating ranges at all times. -
Page 8: Installation Position
Do not install the inverter in: Areas where ammonia, corrosive vapours, acids or salts are present (e.g. fertiliser stores, ventilation openings from cattle sheds, chemical plants, tanneries, etc.) During certain operating phases the inverter may produce a slight noise. For this reason it should not be installed close to living areas. -
Page 9: General Comments Regarding Choice Of Location
The inverter is suitable for installation on a sloping surface. Do not install the inverter on a sloping surface with its connection sockets at the top. Do not install the inverter at an angle on a vertical wall or column. Do not install the inverter horizontally on a vertical wall or pillar. - Page 10 Max. ambient temperatures: -40 °C / +55 °C Relative humidity: 0-100% The airflow within the invert- er is from the left and right to the top (cold air taken in from the left and right, hot air dissipated out of the top). The exhaust air can reach a temperature of 70 °C.

Attaching the Mounting Bracket Safety WARNING! Danger due to residual voltage in capacitors. This may result in an electric shock. ▶ Wait for the capacitors to discharge. The discharge time is five minutes. CAUTION! Danger due to dirt or water on the terminals and contacts of the inverter's con- nection area. -

Page 15: Connecting The Inverter To The Public Grid (Ac Side)
▶ Maintenance and servicing in the power stage set of the inverter must only be carried out by Fronius-trained service technicians. CAUTION! Risk of damage to the inverter as the result of incorrectly tightened terminals. Incorrectly tightened terminals can cause heat damage to the inverter that may result in a fire. -

AC terminals Ground conductor / earthing Phase conductor Neutral conductor Max. cross-section of each conductor cable: 16 mm² Min. cross-section of each conductor cable: in accordance with the fuse rating on the AC side, but at least 2.5 mm² The AC cables can be connected to the AC terminals without ferrules. -
Page 17: Requirements For The Neutral Conductor
IMPORTANT!Repeat the procedure if the cable has been disconnected and is to be re-connected. Requirements Note! for the neutral Ensure that the grid neutral conductor is grounded. This may not be the case conductor for IT grids (insulated grids with no grounding); it will then not be possible to use the inverter. -
Page 18: Maximum Fuse Rating On Alternating Current Side
IMPORTANT! The PE ground conductor of the AC cable must be laid in such a way that it is the last to be disconnected in the event that the strain-relief device should fail. This can be ensured, for example, by making it somewhat longer and by laying it in a loop. - Page 19 For this situation, a type A residual current protective device is generally ad- equate. In particular cases, and depending on local factors, however, the type A residual current protective device may trip at the wrong time. For this reason, Fronius recommends that an RCD suitable for frequency con- verters be used.

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. - Page 21 WARNING! Danger from inadequate ground conductor connection. This can result in serious injury and damage to property. ▶ 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.

The cable cross-section of the DC con- nection lead and the jumpering must be the same.

Page 28: Data Communication
To cater for this eventuality, a suitable blanking cover (42,0405,2020) is available from Fronius as an option. IMPORTANT! If data communication cables are wired into the inverter, observe the following points: Depending on the number and cross-section of the data communication cables that are being introduced, take the relevant blanking plugs out of the sealing insert and insert the data communication cables. - Page 29 IMPORTANT! Observe the ESD guidelines when handling option cards. IMPORTANT! Only one Fronius Datamanager in master mode is permitted per Fronius Solar Net ring. Switch any other Fronius Datamanagers to slave mode or remove them. Seal off the unoccupied option card slot by replacing the cover (item number 42,0405,2094);...
