All inverters are designed to be dust-tight. However, in areas with a 
heavy build-up of dust, the thermal efficiency may still be impaired by 
dust forming on the cooling surfaces. Regular cleaning is necessary in 
such situations. It is therefore not recommended to mount the device in 
rooms or areas in which a heavy build-up of dust is expected. 
Do not install the inverter in:
- greenhouses
- storage or processing areas for fruit, vegetables or winegrowing 
products  
- places used to prepare grain, green fodder or animal feeds
The inverter is designed to be installed vertically on a vertical wall or pil-
lar.
The inverter is suitable for horizontal installation.
The inverter is suitable for installation on a sloping surface. 
Do not install the inverter on a sloping surface with its connection sockets 
facing upwards. 
Do not install the inverter at an angle on a vertical wall or pillar. 
Do not install the inverter horizontally on a vertical wall or pillar.
