For high power usage combined with low input line voltages (shaded region),
use only the power cord with the 20 A plug. Select the proper fuse based on the
ranges shown in Figure 29.

For example, assume that your TLA721 benchtop system consists of four
TLA7Q4 Logic Analyzer Modules and one TLA7E2 DSO Module. Also assume
that you will be operating the mainframe at 90 VAC.
Add 121 Watts (for the DSO Module) + 4 X 75 Watts (for the logic analyzer
modules) + 70 Watts (for the controller) + 100 Watts for the mainframe to come
up with a total value of 591 Watts.
Because the power consumption (at 90 VAC) is approaching the shaded area of
the graph in Figure 29, you should consider using the 20A power cord.
NOTE
. If you are configuring an expansion mainframe, remember to use the
power value for the expansion module instead of the benchtop controller.
