Chapter 3 Wiring of Drive 33
3.5 Attention for Main Circuit Wiring
3.5.1 Power Supply Wiring
It is forbidden to connect the power cable to the drive output terminals;
otherwise, the internal components of the drive will be damaged.
To facilitate the input side over current protection and power failure
maintenance, the drive shall connect to the power supply through the
circuit breaker or leakage circuit breaker and contactor.
Please confirm that the power supply phases, rated voltage are
consistent with that of the nameplate, otherwise, the drive may be
damaged.
3.5.2 Motor Wiring
It is forbidden to short circuit or ground the drive output terminals;
otherwise the internal components of the drive will be damaged.
Avoid short circuit the output cable and the drive enclosure, otherwise
there is the risk of electric shock.
It is forbidden to connect the output terminals of the drive to the capacitor
or LC/RC noise filter with phase lead, otherwise, the internal components
of the drive may be damaged.
When contactor is installed between the drive and the motor, it is
