Fronius will not bear any costs for production downtimes, or for installations, 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). -
Page 8: Installation Location And Position
Installation location and position Selecting a loca- Please observe the following criteria when choosing a location for the inverter: tion The inverter is suitable for indoor installation. The inverter is suitable for outdoor installation. Because of its NEMA4X protection class, the inverter is not sus- ceptible to hose water on any side and can also be operated in moist environments. -
Page 9: Installation Position
During certain operating phases the inverter may produce a slight noise. For this reason it should not be installed in an occupied liv- ing 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, etc. -
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 ver- tical wall or column. -
