Installing the Fan (MD580‑4T426(‑L) to MD580‑4T820(‑L))
① Install the fan in a reverse procedure to removal. Pay attention to the direction of the
fan.
② Align the fan box to the rail and push it into the AC drive.
③ Connect the power cable connectors before fixing the fan cover. After replacement,
ensure that the air flows upwards.
5.4 Storage
For storage of the AC drive, observe the following:
● To store the drive, pack the AC drive with the original packing box provided by
Inovance.
● Do not expose the drive to the environment with moisture or high temperature, or
place it outdoors in direct sunlight for an extended period.
● The electrolytic capacitor will deteriorate after being stored for a long time.
Therefore, the AC drive must be switched on once for at least five hours every six
months. The input voltage must be increased slowly to the rated value by using a
voltage regulator. Contact professionals for technical support if necessary.
