1.1.5 Maintenance
- 4 -
GK500 User Manual Chapter 1 Safety Precautions
All pluggable components can be inserted or pulled out only when power has
been cut 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 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
- 5 -
Chapter 1 Safety Precautions GK500 User Manual
drive since this may result in drive damage as a result of over-temperature.
1.2.5 Insulation of the motor
In view of the fact that the drive output is PWM high frequency chopping voltage
accompanied by higher harmonics, the noise, temperature rise and vibration of the motor
is higher compared with sinusoidal voltage. Particularly this debases motor insulation.
Therefore, the motor should be subjected to insulation inspection before initial use or
reuse after being stored for a long period of time. The motor in regular service should
also be subjected to regular insulation inspection so as to avoid the drive damage as a
result of motor insulation damage.
1.2.6 Derating
The drive heat dissipation by forced air cooling degrades ascribed to the thin air in
high-altitude areas, as well as the electrolyte of electrolytic capacitors is more volatile,
which can result in reduction in product life. Drive should be derated when used in an
area at the altitude above 1000 meters. It is recommended to derate 1% for every 100m
when the altitude is above 1000 meters.

WARNING
Only qualified personnel familiar with AC motor drives are allowed to implement
wiring. Failure to comply may result in equipment damage and/or personnel
injury even death.
Wiring should be in strict accordance with this manual, otherwise hazard of
electric shock or equipment damage exists.
Make sure input power supply has been completely disconnected before wiring
operation. Failure to comply will result in personnel injury even death.
All wiring operations and lines should comply with EMC and national and local
industrial safety regulations and/or electrical codes. The conductor diameter
should be in accordance with recommendations of this manual. Otherwise,
hazard of equipment damage, fire, and/or personnel injury exists.
Screws or bolts for terminal wiring must be screwed tightly.
AC 220V signal is prohibited from connecting to other terminals than control
terminals RA, RB and RC.
ATTENTION
Signal wires should to the best of possibility be away from main power lines. If
this cannot be ensured, vertical cross arrangement should be adopted, reducing
EMI interference to the signal wires as much as possible.
