 Use a single fuse for 1-phase input inverter models.
For 3-phase input models, each L1(L)/L2/L3(N) phase must be fused.
 Select suitable three-phase squirrel cage induction motor for inverter.
 If an inverter drives mote than one motor in parallel, the total operating current should be less
than the inverter rated current.
Suitable thermistor should be installed on each motor.
 Do not install capacitor, LC, RC between inverter and motor.
