Figure 4-34 Example 2: installation in cabinet with mounting plate
We recommend that you attach a cover and filtered fan to the cabinet.
The filtered fan must be fitted in such a way that the cooling air required by the drive line-up
is not restricted. This can be determined by establishing the total cooling air required by the
individual components. This information is available in the technical data.
Note
If the cooling air requirement is not covered by the filtered fan, the components cannot
output their specified power.
The filters with a filtered fan must be regularly checked for dirt and cleaned if necessary.
