Page 5: Safety
Safety General This manual contains important instructions for the inverter that must be fol- lowed during installation and maintenance of the inverter. The inverter is designed and tested according to international safety require- ments. Due to its electrical and electronic components, certain precautions must be taken when installing and operating the inverter. -
Page 6: Installation Location And Position
Installation location and position Explanation of WARNING! safety instruc- tions Indicates a potentially dangerous situation. ▶ Death or serious injury may result if appropriate precautions are not taken. CAUTION! Indicates a potentially harmful situation. ▶ Minor injury or damage to property may result if appropriate precautions are not taken. -
Page 7: Intended Use
▶ Only put the inverter into operation with the fixing screws securely tightened. Notice! 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. -
Page 8: Location Selection
When configuring the photovoltaic system, make sure that all components are operating completely within their permitted operating range. All measures recommended by the solar module manufacturer for maintaining solar module properties must be followed. Follow all grid operator regulations regarding grid power feed and connection methods. -
Page 9: Installation Position Of The Inverter
During certain operating phases the inverter may produce a slight noise. For this reason, it should not be installed in an oc- cupied living area. Do not install the inverter in: areas where there is an increased risk of accidents from farm animals (horses, cattle, sheep, pigs, etc.) Stables or adjoining areas storage areas for hay, straw, chaff, animal feed, fertilizers,... -
Page 10: General Location Selection
Do not install the inverter in a sloping position on a vertical wall or column. Do not install the inverter in a horizontal position on a vertical wall or column. Do not install the inverter with the connections upwards on a vertical wall or column. -
Page 11: Example: Installation Of Several Inverters
Only install on a solid, non-flammable surface Max. ambient temperatures: -40 °F/+140 °F (-40 °C/+60 °C) Relative humidity: 0–100% The air flow direction within the inverter is from right to top (cold air intake on the right, hot air outflow at the top).
