Recommended Clearances:
To guarantee optimal operation and adequate heat dissipation for the inverter as well as a good
connection quality when using the SMA Cellular LTE Modem Kit, 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
®
or
Canadian Electrical Code
®
CSA C22.1
Under certain conditions, the
National Electrical Code
®
or the
Canadian Electrical Code
®
CSA C22.1 specify greater clearances.
• Ensure that the prescribed clearances in accordance with the
National Electrical Code
®
or
Canadian Electrical Code
®
CSA C22.1 are adhered to.
☐ Maintain 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.
