F-10 System Loading and Heat Dissipation
Calculating Heat
Dissipation Use the following table when you need to determine the heat dissipation of
your system for installation in an enclosure. For System Loading, take the value
from the appropriate system loading worksheets on pages F-4, F-5, F-8 or F-9:
