Therefore, to ensure that enough cooling air enters the cabinet, open an air inlet large enough on the cabinet door. The air flows from bottom to top after being heated. Therefore, the cabinet air inlet must be at least 50 mm lower than the air inlet of the drive, as shown in the following figure.
  • Page 21 Preparation Where multiple AC drives are installed in one cabinet, if air is blown into the air inlet with a fan from the outside, air distribution of the drives in the cabinet will be affected, thereby af‑ fecting the overall heat dissipation effect. Therefore, do not install the fan at the cabinet air inlet to blow air into the cabinet.
