PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
Disconnect AC input power before connecting any wiring to the AC motor drive.
Even if the power has been turned off, a charge may still remain in the DC-link
capacitors with hazardous voltages before the POWER LED is OFF. Do not touch
the internal circuits and components.
There are highly sensitive MOS components on the printed circuit boards.
These components are especially sensitive to static electricity. Take anti-static
measures before touching these components or the circuit boards.
Never modify the internal components or wiring.
Ground the AC motor drive by using the ground terminal. The grounding method
must comply with the laws of the country where the AC motor drive is to be
installed.
DO NOT install the AC motor drive in a location
with high temperature, direct
sunlight or inflammable materials or gases.
Never connect the AC motor drive output terminals U/T1, V/T2 and W/T3 directly
to the AC mains circuit power supply.
After finishing the wiring of the AC motor drive, check if U/T1, V/T2 and W/T3 are
short-circuited to ground with a multimeter. Do NOT power the drive if short circuits
occur. Eliminate the short circuits before the drive is powered.
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.
For 115V models, the range is between 85–132 V.
For 230V models, the range is between 170–264 V.
For 460V models, the range is between 323–528 V.
Refer to the table below for short circuit rating:
Model (Power) Short circuit rating
115V 5 kA
230V 5 kA
460V 5 kA
Only qualified persons are allowed to install, wire and maintain the AC motor
drives.
Even if the three-phase AC motor is stopped, a charge with hazardous voltages
may still remain in the main circuit terminals of the AC motor drive.
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.
