・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 60245 IEC57). For example, use wiring such as YZW.
・The user must ensure that this unit is connected only to a power supply system which fulfils the requirement
above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.
