☐ Observe the recommended clearances to walls as well as to other inverters or objects.
☐ If multiple inverters are mounted in areas with high ambient temperatures, increase the
clearances between the inverters and ensure sufficient fresh-air supply.
Figure 4: Recommended clearances
Permitted and prohibited mounting positions:
☐ The inverter must be mounted in one of the permitted positions. This will ensure that no
moisture can penetrate the inverter.
☐ The inverter should be mounted in such a way that LED signals can be read without difficulty.
