Chapter 1 Safety Precautions
- 5 -
ATTENTION
Do not touch the electric components w ith bare hands during maintenance, and
troubleshooting. Failure to comply may result in component damage due to ESD.
All pluggable components can be inserted or pulled out only w hen pow er has been
turned off.
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 necessary, please use booster to rise or drop the voltage to regulated
voltage range.
1.2.2 Surge Protection
This series of drives are furnished w ith surge suppressor that has certain resistance to lightning
induction. How ever, users in areas w here lightning occurs frequently need to mount an external
surge suppressor in front of pow er input side of the drive.
1.2.3 Operation of Contactor
As to the configuration of peripheral devices recommended by this manual, it is necessary to
mount a contactor betw een the pow er supply and input side of the drive. Such a contactor
should not be used as a control device to start and stop the drive, as frequent charging &
discharging shall reduce the service life of internal electrolytic capacitors.
When it is necessary to mount a contactor betw een the drive output and the motor, it should be
ensured the drive is in a non-output status before sw itch-on/sw itch-off of such a contactor.
Failure to comply may result in damage to the drive.
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 betw een the motor and the drive shall effectively
reduce output noise, avoiding interference to other surrounding equipment.
Be sure not to mount phase-shifting capacitor or surge absorber at output side of the drive
since this may cause damage to the drive as a result of over-temperature.
