・The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one size thicker in diameter. Make sure the
power-supply voltage does not drop more than 10%. Make sure that the voltage imbalance between the phases is 2% or less.
・Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57).
For example, use wiring such as YZW.

The maximum allowable length of transmission cables via outdoor units (both centralized control transmission cables and indoor-outdoor transmission cables) is
Remarks
500 m (1640 ft).
The maximum allowable length of transmission cables from the power supply unit to each outdoor unit or to the system controller is 200 m (656 ft).
* Do not use a single multiple-core cable to connect indoor units that belong to different refrigerant systems. The use of a multiple-core cable may result in signal transmission errors and
malfunctions.
* Ensure shield continuity when extending the transmission cable.
