"a)Supplier side" - "b)Consumer side" = 350mA - 740mA = -390mA
a) It is necessary to add an extension power supply unit since the capacity on the
consumer side b) is 390mA larger than the capacity on the supplier side a).
3) Restriction for the number of connectable units
a) Expansion board
There is no problem since this configuration does not include an expansion board.
b) Special function unit/block
This configuration includes the following 3 special function units/blocks.
There is no problem since up to 7 special function units/blocks can be connected.

c) Other restriction
In some models, only 1 unit can be connected to the main unit.
When connecting 2 or more units, it is necessary to add the extension power supply unit. (Refer to
Subsection 1.10.2.)
This configuration includes the following equipment that falls under the restriction for the number of
connectable units.
