Page 10: Installation Position Of The Inverter
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. The inverter is designed to be dustproof in principle. However, in areas of high dust accumulation, the cooling surfaces can become dusty, which can impair the thermal performance. -
Page 11: General Location Selection
Do not install the inverter with the connections upwards on a vertical wall or column. Do not install the inverter overhanging with the connections upwards. Do not install the inverter overhanging with the connections down- wards. Do not install the inverter on the ceiling.
