"a)Supplier side" - "b)Consumer side" = 480mA - 650mA = -170mA
a) It is necessary to add an extension power supply unit since the capacity on the
consumer side b) is 170mA larger than the capacity on the supplier side a).
3) Restriction for the number of connectable units
a) Special adapter
The FX
connect the special adapter to the main unit.
There is no problem with this configuration since only 2 special communication
adapters are connected.
b) Special function unit/block
This configuration includes the following 5 special function units/blocks.
Because only up to 4 units can be connected to the main unit, it is necessary to add an
extension power supply unit.

c) Other restrictions
In some models, only up to 4 units (or 5 units in certain conditions) can be connected to a single main
unit. When connecting 5 or more units, it is necessary to add an extension power supply unit. (Refer to
Subsection 1.10.1.)
This configuration includes the following equipment that fall under the restriction for the number of
connectable units.
- FX
2NC
- FX
0N
There is no problem with this configuration since it satisfies the restriction for the
number of connectable units (4 units).
