terminals. Never connect three-phase power supply to output terminals U/T1, V/T2 and
W/T3. Failure to comply may result in equipment damage.
Install braking resistors at terminals and B2 only. Failure to comply may result in
equipment damage.

Since all adjustable frequency AC drives from GTAKE have been subjected to hi-pot
test before delivery, users are prohibited from implementing such a test on this
equipment. Failure to comply may result in equipment damage.
Signal wires should be away from main power lines to the best of the possibility. If this
cannot be ensured, vertical cross-arrangement shall be implemented, otherwise
interference noise to control signal may occur.
If motor cables are longer than 100m, it is recommended output AC reactor be used.
Failure to comply may result in faults.
Drives which have been stored for more than 2 years should be used with voltage
regulator to gradually boost the voltage when applying power to the drives. Failure to
comply may result in equipment damage.
Be sure to implement the wiring as per Section 3.4 before applying power to the drive.
Failure to comply may result in equipment damage and/or electric shock hazard.
Be sure to confirm the completion and correctness of the drive wiring and close the
cover before applying power to the drive. Do not open the cover after applying power.
Failure to comply may result in electric shock hazard.
After applying the power, never touch the drive and peripheral circuits no matter what
state the drive is under, otherwise there will be electric shock hazard.
Prior to running the drive, make sure there is no person in surrounding area who can
reach the motor so as to prevent personal injury.
When the drive is running, foreign bodies should be prevented falling into the
equipment. Failure to comply may result in faults and/or equipment damage.

Only qualified technicians familiar with adjustable frequency AC drives are allowed to
perform signal test during operation. Failure to comply may result in equipment damage
and/or personal injury.
Never change the drive parameters at will. Failure to comply may result in equipment
damage.
Make sure the number of phases of power supply and rated voltage are consistent w ith
product nameplate. If not, contact the seller or GTAKE.
Check there are no short circuits in peripheral circuits connected with the drive, and
make sure the connection is tight. Failure to comply may result in equipment damage.
Make sure the motor and associated machinery are within allowable range of service
prior to operation. Failure to comply may result in equipment damage.
Never touch fans, heat sink and braking resistor with bare hands. Failure to comply may
result in equipment damage and/or personal injury.
It is not allowed to start & stop the drive frequently via direct switching power on or off.
Failure to comply may result in equipment damage.
Make sure the drive is in a non-output status before switch-on/sw itch-off of the drive
output and/or contactor. Failure to comply may result in equipment damage.
Only qualified technicians are allowed to implement the maintenance, and
troubleshooting.
Never implement the maintenance, and troubleshooting before power supply has been
turned off and discharged completely. Failure to comply may result in equipment
damage and/or personal injury.
To avoid an electric shock hazard, wait at least 10 minutes after the power has been
turned off and make sure the residual voltage of the bus capacitors has discharged to
0V before performing any work on the drive.
After the replacement of the drive, be sure to perform the same procedures in strict
accordance with the above-noted rules.

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.
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.
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.

Chapter 1 Safety Precautions GK600E User Manual
- 6 -
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 damage to the drive as a result of motor insulation damage. A 500V
voltage mode mega-ohmmeter is recommended to use for the measurement of the motor
insulation, during which, it is essential to disconnect the motor from the drive. Normally, the
insulation resistance of the motor should be bigger than 5MΩ.
1.2.6 Derating
Due to the thin air in high-altitude areas, the radiating performance of the drive with forced air
cooling may degrade while 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.

All w iring 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.
Since leakage current of the drive may exceed 3.5mA, for safety's sake, the drive and
the motor must be grounded so as to avoid hazard of electric shock.
Be sure to perform w iring in strict accordance with the drive terminal marks. Never
connect three-phase power supply to output terminals U/T1, V/T2 and W/T3. Failure to
comply will result in equipment damage.
