3-3 Power Supply Units
Use an NJ-series Power Supply Unit to supply power to an NJ-series CPU Rack or Expansion Rack.
Precautions for Correct UsePrecautions for Correct Use
• Do not use the Power Supply Units in the system beyond the rated supply capacity range
given in the following specifications. Doing so may result in operation stopping, incorrect oper-
ation, 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. Oper-
ation 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.
