What is the length of the connecting wire between the indoor and outdoor units of the Mijia Air Conditioner Pro Eco 5-Star 1 PK Inverter?

The connecting wire between the indoor and outdoor units of the Mijia Air Conditioner Pro Eco 5-Star 1 PK Inverter has a length of 5 meters and a specification of 4×1.0mm². This means the cable consists of four individual conductors (live wire, neutral wire, earth wire, and signal wire), each with a cross-sectional area of 1.0mm², ensuring efficient and stable power transmission as well as signal communication between the indoor and outdoor units.
The information on the four conductors is as follows:
1. The live wire is colored brown and carries the current from the power source to the device;
2. The neutral wire is colored blue and completes the circuit by returning the current to the power source;
3. The earth wire is colored yellow-green and serves as a safety wire to prevent electrical shock by providing a path for the current to flow into the ground in case of a fault;
4. The signal wire is colored white and is used for communication between the indoor and outdoor units, such as sending operational signals or feedback.
Note:
Part of the wire is located inside the air conditioner, and the actual length of wire exposed outside the device is shorter than 5 meters.
