Planning the cabinet installation 39
Preventing the recirculation of hot air
Prevention the air recirculation outside the cabinet
Prevent hot air circulation outside the cabinet by leading the outcoming hot air away from
the area where the inlet air to the cabinet is taken. Possible solutions are listed below:
• gratings that guide air flow at the air inlet and outlet
• air inlet and outlet at different sides of the cabinet
• cool air inlet in the lower part of the front door, and an extra exhaust fan on the roof of
the cabinet.
Prevention the air recirculation inside the cabinet
Prevent hot air circulation inside the cabinet with eg, leak-proof air baffles at the positions
shown in the diagrams in section Required free space around the drive module below. No
gaskets are usually required.
Required free space around the drive module
Free space around the drive module is needed for ensuring that sufficient cooling air flows
through the module and that the module cools properly.
