Functional Description
4.10 Inverter Cooling Fin Temperature Control
Outline
This control will restrict the compressor upper limit frequency in order to protect the electronic
components in the switch box from overheating (L4-error activation).
By lowering the compressor frequency, the current drawn by the compressor will be reduced
and as a result the temperature inside the switch box will drop.
