Inverter Protection Control
Inverter current protection control and inverter fin temperature control are performed to prevent
tripping due to a malfunction, or transient inverter overcurrent, and fin temperature increase.
In the case of multi-outdoor-unit system, each INV compressor performs these controls in the
following sequence.
