5 Mounting
☐ When mounting with profile rails, an attachment or fixation by loading is required. When
mounting with profile rail, SMA recommends to bolt the profile rail e.g. to the profile of the
module frame or to attach a sheet metal (which can be weighted with stones or with
sandbags) at the profile rails. This will ensure that the inverter is fixed.
Recommended Clearances:
To guarantee optimal operation and adequate heat dissipation for the inverter, the following
requirements for clearances should be observed. This will prevent the inverter power output from
being reduced due to excessive temperatures. However, smaller clearances are permitted without
causing any risk.
Prescribed clearances in accordance with the National Electrical Code
Under certain conditions, the National Electrical Code
• Ensure that the prescribed clearances in accordance with the National Electrical Code
are adhered to.
☐ Maintain the recommended clearances to roof edges, skylights, walls as well as to other
inverters or objects. This ensures that the load-break switches on the inverter can be operated
easily and the LED signals can be read without difficulty.
☐ For possible service deployments, SMA recommends ensuring sufficient clearance from walls,
other inverters or objects on all four sides of the inverter enclosure. Non-fulfillment of these
criteria may restrict servicing.
☐ If multiple inverters are mounted in areas with high ambient temperatures, increase the
clearances between the inverters and ensure sufficient fresh-air supply.
