CJ2 CPU Unit Hardware User’s Manual
A CJ-series PLC must be mounted inside a control panel on DIN Track. Normally the CPU Rack is
installed on top and the Expansion Racks under it.
• Consider the width of wiring ducts, wiring, ventilation, and Unit replacement when determining the
space between Racks.
Additional Information
A CJ-series PLC must be mounted on DIN Track. It cannot be mounted with screws.
• Whenever possible, route I/O wiring through wiring ducts or raceways. Install the duct so that it is
easy to fish wire from the I/O Units through the duct. It is handy to have the duct at the same
height as the Racks.
