DO NOT install the AC motor drive in a location subject to high temperature, direct
sunlight, high humidity, or splash of water droplets.
Use the AC motor drives only within specification. Failure to comply may result in
fire, explosion or electric shock.
When the motor cable between AC motor drive and motor is too long, the
insulation layer of the motor may be damaged. Use a frequency inverter-duty
motor or add an AC output reactor to prevent damage to the motor. Refer to
Appendix B “Reactor” for details.
The rated voltage of power system to install motor drives is listed below. Ensure
that the installation voltage is in the correct range when installing a motor drive.
1. For 230V models, the range is between 180V~264V
2. For 460V models, the range is between 342V~528V
The performance of electrolytic capacitor will degrade if it is not charged for a long
time. It is recommended to charge the drive which is stored in no charge condition
every 2 years for 3~4 hours to restore the performance of electrolytic capacitor in
the motor drive. Note: When power up the motor drive, use adjustable AC power
source (ex. AC autotransformer) to charge the drive at 70%~80% of rated voltage
for 30 minutes (do not run the motor drive). Then charge the drive at 100% of rated
voltage for an hour (do not run the motor drive). By doing these, restore the
performance of electrolytic capacitor before starting to run the motor drive. Do
NOT run the motor drive at 100% rated voltage right away.
Pay attention to the following precautions when transporting and installing this
package (including wooden crate and wood stave)
1. If you need to deworm the wooden crate, do NOT use fumigation or you will
damage the drive. Any damage to the drive caused by using fumigation voids
the warranty.
2. Use other methods, such as heat treatment or any other non-fumigation
treatment, to deworm the wood packaging material.
3. If you use heat treatment to deworm, leave the packaging materials in an
environment of over 56°C for a minimum of thirty minutes.
If the motor drive generates leakage current goes over AC 3.5 mA or over DC 10
mA on a protective earth (PE) conductor, the PE conductor must be a copper wire
with a cross section of minimum 10mm
2
or an aluminum wire with a cross section
of at least 16mm
2
. You can also install an earth-leakage circuit breaker
(ELCB).
