5.5.2 Fan air outlet
Each fan has a choice of three air outlets; front, top or rear. These are selected by removing the appropriate
cover and using this cover to block the unwanted outlet.
The air outlet must not be obstructed and should preferably be ducted out of the control enclosure. Figure 4-5
shows the six fixing centres on each of the fan outlets for connecting a duct.
To keep personnel from the main air and noise path it is recommended that the airflow outlet is through the
top or rear of the drive enclosure.
These fans are normally fitted at the top of the enclosure, outside of the normal accidental finger access range.
If they are installed in a position where the fan is accessible, mechanical protection must be provided.
