Illustration 8: Ventilation Arrangements on the Cabinet (Examples)
5.2.2 Steering the Internal Airflow
Cooling air must be sucked in through the ventilation gaps on the door and blown out at the top of the enclosure. To steer the hot
air from the power unit to the outlet at the top of the enclosure and prevent it from circulating back to the fan blower, use either of
the following arrangements:
A: Install a closed air duct from the power unit to the outlet on top of the enclosure (1 in
Illustration 9).
B: Install shields in the gaps between the power unit and the cabinet walls (2 in Illustration 9). Place the shields above the air outlet
gaps at the sides of the unit.
In enclosure size FR12, close the opposing gaps in the upper part of the cabinets with a sheet metal plate to ensure proper cooling.
