Prescribed clearances in accordance with the National Electrical Code
Canadian Electrical Code
Under certain conditions, the National Electrical Code
CSA C22.1 specify greater clearances.
• Ensure that the prescribed clearances in accordance with the National Electrical Code
or Canadian Electrical Code
☐ 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 Solar Technology AG 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.
