series Units on the CPU Rack and Expansion Racks.
CPU Rack
The CPU Rack consists of an NJ-series CPU Unit, an NJ-series Power Supply Unit, CJ-series
Configuration Units, and a CJ-series End Cover. Up to 10 CJ-series Configuration Units can be con-
nected.

* The I/O Control Unit is required only to connect an Expansion Rack. It must be connected immediately to the
right of the CPU Unit.
Even though the NJ-series Controllers do not have Backplanes, the term "slot" is still used to refer to
the location of Units. Slot numbers are assigned in order to Units from left to right on the CPU Rack (slot
0, slot 1, slot 2, etc.).
