Omron CJ1W-ID Series User Manual page 73

Note A CJ-series Power Supply Unit cannot be used to supply power to an NJ-system CPU Rack or Expansion
Rack.
If you connect a CJ-series Power Supply Unit to a CPU Rack, an Incorrect Power Supply Unit Connected
error will occur, and the CPU Unit will not operate. The RUN indicator will flash at a 3-s interval and the
ERROR indicator will light.
If you connect the Power Supply Unit to an Expansion Rack, operation is performed without error detection.
Normal operation, however, may be unstable due to insufficient supplied power. Also, an Internal NJ-series
Bus Check Error (i.e., a Controller error in the major fault level) may occur when the power is interrupted.
Note The Power Supply Unit may continue to supply power to the rest of the Controller for a few seconds after the
power supply turns OFF and the PWR indicator is lit during this time. If the NJ-series NJ-PD3001 Power
Supply Unit is used, confirm that the PWR indicator is not lit when the power supply is tuned ON again after
the power supply turns OFF.
Precautions for Safe Use
• Do not use the Power Supply Units in the system beyond the rated supply capacity ranges.
Doing so may result in operation stopping, incorrect operation, or failure to correctly back up
required data at power interruptions.
• Use only NJ-series Power Supply Units on NJ-series CPU Racks and Expansion Racks.
Operation is not possible if you use a CJ-series Power Supply Unit with an NJ-series CPU Unit
or an NJ-series Power Supply Unit with a CJ-series CPU Unit.

Specifications
An I/O Control Unit is required to connect an NJ-series
Expansion Rack to an NJ-series CPU Rack. The I/O Con-
trol Unit must be connected immediately to the right of

II101) on the Expansion Rack with a CS/CJ-series I/O
Connecting Cable.
Specifications
The End Cover must be connected to the right end of the
NJ-series CPU Rack. (A Controller error in the major fault
level will occur if the End Cover is not connected to the
right end of the Rack.) One End Cover is provided with
the CPU Unit and with an I/O Interface Unit.
