2-1-3 Expansion Racks
CJ-series Expansion Racks can be connected to the CPU Rack to expand the number of Units in the
System beyond the CPU Rack. Up to 10 I/O Units can be mounted to each Expansion Rack and a total
of 3 Expansion Racks can be connected.
Mount an I/O Control Unit immediately to the right of the CPU Unit, and mount the I/O Interface Unit
immediately to the right of the Power Supply Unit on the Expansion Rack. Mounting them in other loca-
tions may cause malfunctions.
