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

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.
