Steering air flow

Cooling air must be taken 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
(A in Figure 40).
B. Install shields in the gaps between the power unit and the cabinet walls (B in Figure 40).
Place the shields above the air outlet gaps at the sides of the module.

NOTE! If a flat roof is used, mount a V-shaped air guide on the underside of the roof to direct the air
flow horizontally. See Figure 41.
