be caused due to the influence of the distributed capacitance, thus damaging the
motor insulation or produce large leakage current to trigger inverter over current
protection. When the length of the motor cable is longer than 100 meters, AC output
reactor shall be installed.
e) Grounding terminal
:
The terminal must be grounded reliably, and the resistance of the ground wire must
be less than 0.1Ω. Otherwise, fault may be caused, or the inverter may be damaged.
Do not share the grounding terminal
and terminal N of zero line of the power
supply.
