1.2 Other Considerations
1.2.1 Input Power Supply
This series of drives are not applicable to applications out the range of operating voltage
as set forth in this manual. If the input voltage is not in the required range, please use
booster to rise or drop the voltage to the stated voltage range.
1.2.2 Surge Protection
This series of drives are furnished with surge suppressor that has certain resistance to
lightning induction. However, users in areas with frequent occurrence of lightning need to
mount an external surge suppressor in front of the drive power input side.
1.2.3 Operation of Contactor
As to the configuration of peripheral devices recommended by this manual, it is
necessary to mount a contactor between the power supply and this drive input side.
Such a contactor should not be used as a control device for start and stop of the drive, as
frequent charging & discharging shall reduce the service life of internal electrolytic
capacitors.
When it is necessary to mount a contactor between the drive output and the motor, it
should be ensured the drive is in a non-output status before switch-on/switch-off of such
a contactor. Failure to comply may result in drive damage.
1.2.4 Output Filter
Since the drive output is PWM high frequency chopping voltage, mounting filter devices
such as an output filter and an output AC reactor between the motor and the drive shall
effectively reduce output noise, avoiding interference to other surrounding equipments.
If the length of cable between the drive and the motor exceeds 100m, an output AC
reactor is recommended to use with the purpose of preventing drive fault as a result of
overcurrent caused by excessive distributed capacitance. An output filter is optional
depending on field requirements.
Be sure not to mount phase-shifting capacitor or surge absorber at output side of the
