CJ2 CPU Unit Hardware User’s Manual

CS/CJ-series I/O Connecting Cables are used to connect the CPU Rack and Expansion Racks.

z CS/CJ-series I/O Connecting Cables

• These connectors are equipped with easy-lock connectors.

• Use them to connect the CPU Rack to an Expansion Rack or to connect two Expansion Racks.

• The CJ-series I/O Connecting Cables are used to connect the I/O Control Unit on the CPU Rack

to the I/O Interface Unit on an Expansion Rack or to connect the I/O Interface Units on two Expan-

sion Racks.

• Install the Racks and select I/O Connecting Cables so that the total length of all I/O Connecting

Cables does not exceed 12 m.

• The following diagram shows where each I/O Connecting Cable must be connected on each

Rack. The Rack will not operate if the cables aren’t connected properly. (The “up” direction is

towards the CPU Unit and “down” is away from the CPU Unit.)
