1.7.1 How to Design the Connection Layout of the Power Supply
Follow the procedure below to design the connection layout of the
power supply.
(1) Temporarily determine the position of a power supply.
(2) Calculate the sum of the power consumption of all nodes to be
placed.
(3) Calculate the length of the main line in the temporary layout and
use the graph to roughly obtain the capacity of current that can
be supplied to cables.
(4) Verify that the power supply capacity is greater than the power
consumption.
(5) Make verification after changing the layout of the power supply.
(6) When the conditions are not satisfied in the rough calculation
from the graph in step (3), calculate the amount of power to be
supplied with the expression and then make verification again.
(7) When the conditions are not satisfied in the calculation in step
(6), install multiple power supplies, provide multiple power
systems, and check whether the amount of current supplied from
each power supply satisfies the conditions.
