*1. When an Additional I/O Power Supply Unit is connected to the CPU Rack of a CPU Unit, the maximum I/O
power supply current value may be smaller than that of the Additional I/O Power Supply Unit. For example,
the maximum I/O power supply current for the CPU Rack of an NX1P2 CPU Unit is 4 A. For the maximum
I/O power supply current of the CPU Rack, refer to Maximum I/O Power Supply Current under Designing the
I/O Power Supply from the NX Bus in the hardware user’
s manual for the CPU Unit to which NX Units are
connected.
