9.1.4 Storage of the AC Drive
For storage of the AC drive, pay attention to the following two aspects:
1)
Pack the AC drive with the original packing box provided by Inovance.
2) Long-term storage degrades the electrolytic capacitor. Thus, the AC drive must be
energized once every 2 years, each time lasting at least 5 hours. The input voltage
must be increased slowly to the rated value with the regulator.
