for inverter, between indoor unit and outdoor unit connection is LNE (3 wires for power) and one more (4th) for signal. https://youtu.be/9-oUDhE3FkE?si=12MbQqvVzEPF9aF4&t=78
if its 3-wires on the IDU-ODU link, that means your installer will "cheat" by substituting the earth wire as signal cable, thereafter no earth for the ODU
Wow didnt know thatif its 3-wires on the IDU-ODU link, that means your installer will "cheat" by substituting the earth wire as signal cable, thereafter no earth for the ODU
