Mounting options
The distributed inverter box is available in two mounting versions.
Figure 3-1 Floor mounting "With supporting foot" and wall mounting "With mounting brackets"
Clearance for heat dissipation
Maintain a clearance of at least 200 mm on all sides of the distributed inverter box to allow for
heat dissipation.
For mounting with mounting brackets, we recommend using vertical profile bars.
