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.
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.
If you store the AC motor drive in a not-charged condition for more than three
months, the ambient temperature should not be higher than 30°C. Storage longer
than one year is not recommended and could result in the degradation of the
electrolytic capacitors.
Pay attention to the following when transporting and installing this package
(including wooden crate, wood stave and carton box).
1 If you need to sterilize or deworm the wooden crate or carton box, do not
use steamed sterilization or you will damage the VFD. Use other methods to
sterilize or deworm.
2 You may use high temperatures to sterilize or deworm. Leave the packaging
materials in an environment of over 56°C for thirty minutes.
