4.5.2 Heat Dissipation Design
4.5.2.1 Ventilation Requirements
Common heat dissipation methods include the following:
● Natural ventilation
● Forced air cooling
4.5.2.1.1 Air Duct Design
Heat dissipation design of the cabinet door
The cabinet is forcibly cooled by a built-in fan. Therefore, to ensure that enough cooling
air enters the cabinet, open an air inlet with an appropriate size on the cabinet door. For
details on the effective area of the air inlet, see
"4.5.2.1.2 Air Outlet and Inlet
"
on page 39
.
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 below.

Air inlet
The effective area of the air outlet is the actual ventilation area instead of the gross
opening area. The following table describes the minimum ventilation area of the cabinet
air inlet after the drive is installed in the cabinet.
