C. The notes and specifications of wiring
a. The leakage current between ground and the wires that are
connected between inverter and motor, is not the same for
different rated power. The setting of carry frequency (F_81)
relate to the rated power and wire distance. Referred to the
figure shown below.

P.S. The carry frequency is determined by F_081.
b.
If the inverter is used where the altitude is greater than 1000 m,
the relationship between current and altitude should be
mentioned and referred to the figure shown below.
