Protective earth
The memory of the leakage current of inverter, in order to ensure the
safety of the inverter and motor must grounding, grounding resistance
should be less than 10Ω. The grounding wire should be as short as
possible, wire diameter should conform to table 3-3 standard.
Note: the data in the table in only two conductors using the same
metal case is correct, if not so, protective conductor cross-sectional
area should be through the method of conductivity coefficient
equivalent using the determined.
