Do not connect the power supply to VFD output terminals U1, V1, W1,
U2, V2, and W2. The voltage applied to the motor cable may cause
permanent damage to the VFD.
If frequent switchover is needed, you can use the switch/contactor that carries mechanical
interlock to ensure motor terminals are not connected to both the input power cable and VFD
output end simultaneously.
