3.2.2.5 Terminals U, V and W
Capacitor device or surge absorber can not be connected to inverter output
side by terminals U, V and W. Otherwise, it may cause frequent inverter
protection or damage to inverter.
If motor cable is too long, it may generate electrical resonance easily due to
the impact of distributed capacitance and thus damage the motor insulation or
generate higher leakage current to cause inverter protection. When the length
of motor cable is longer than 50m, installing AC reactor at the output side is
necessary.
3.2.2.6 Grounding Terminal
The terminal should be grounded reliably. The resistance value of
grounding cable should be less than 10Ω. Otherwise, it may cause fault or
damage to the inverter.
Do not share the grounding terminal with zero line of power supply.
