Note
For a cabinet that holds multiple AC drives, blowing air into the cabinet using a fan at the
air inlet may disturb the air distribution in the cabinet, affecting the overall cooling effect.
Therefore, do not install any fan at the cabinet air inlet.
For the minimum effective area of the air inlet after the AC drive is installed into the
cabinet, see "
Table 4–2 Minimum effective area of the cabinet air inlet
