  • Page 4 PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.  Disconnect AC input power before connecting any wiring to the AC motor drive.  When wiring, turn off the AC motor drive power first. It takes a certain time for the internal DC capacitor to discharge. A charge may still remain in the DC link capacitors with hazardous voltages before the POWER LED is OFF.
  • Page 5  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.

    The parallel solution model is suitable for AC motor drives with the same power of 220kW and above (C2000 Plus, C2000-HS and C2000-R). It addresses the need for capacity expansion in high-power control by enabling internal communication between two AC motor drives (master/ slave) for parallel expansion control.
