2. Only the professional technicians who have received training can perform
wiring, or it may cause injuries to the equipment and human body.
3. It shall be grounded reliably, or there may be risk of electric shock or fire
accident.
Caution
!
1. Make sure that the input power supply and the rated value of the inverter shall
be consistent, or it may damage the inverter.
2. Make sure that the motor is compatible with the inverter, or the motor may be
damaged or inverter protection may be caused.
3. Do not connect the power supply to the U, V, W terminals, or it may damage
the inverter.
4. Do not connect the brake resistor to the DC bus terminals (+) and (-) directly, or
there may be fire accident.
