PLEASE READ PRIOR TO INSTALLATION FOR SAFETY. II Disconnect AC input power before connecting any wiring to the AC motor drive. 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. These components are especially sensitive to static electricity. Please do not touch these components or the circuit boards before taking anti-static measures. 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 place subjected to high temperature, direct sunlight and inflammables. 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.
Rated voltage of power system to install motor drives is as below, make sure that the installation voltage is within the ranges mentioned below while installing the motor drives: 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. For 575V models, the range is between 425V–660V. Refer to the table below for short circuit rating: Model (Power) Short circuit rating 115V 5 kA 230V 5 kA 460V 5 kA 575V 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
