Chapter 1 Safety Precautions

ATTENTION
Do not touch the electric components with 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 when power 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.
This series of drives support common DC bus input. Users are suggested to consult GTAKE
technical personnel before use.
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 where lightning occurs frequently need to mount an external
surge suppressor in front of power 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 between the power 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 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 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 between the motor and the drive shall effectively
reduce output noise, avoiding interference to other surrounding equipment.
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
