NJ-series Power Supply Units

Model
NJ-PA3001
NJ-PD3001
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.
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.
