Fin overheat

What does E.FIN mean?

This function stops the inverter output if the cooling fin overheats, causing the internal overheat sensor to actuate. This indicates that the inverter's heat dissipation is compromised, potentially due to environmental factors or cooling system issues.

1. 1

   Measure the ambient temperature around the inverter and ensure it is within specified limits.

2. 2

   Inspect the cooling fins for any clogging by dust, dirt, or debris.

3. 3

   Verify that the cooling fan is operating correctly and not obstructed.
