Unit Load Calculation
Worksheet
If you determine that you need to recalculate the unit load for any carrier,
use the instructions on the following worksheet.
NOTE:
You should have a separate copy of the worksheet for each carrier.
See "Unit Loads" in Chapter 1 for information on recalculating unit
loads.
The 391A3 power supply has a maximum rating of 75 unit loads. If your
system contains a 391A1 or 391A2 power supply module, and the unit
loads for that carrier will exceed 54, it is recommended that a 391A3
power supply be installed in the system. Auxiliary Power Units cannot be
used with the 391A3 power supply.
