Precautions for Correct Use
Always use separate power supplies for the Unit power supply and the I/O power supply. If
you supply power from the same power supply, noise may cause malfunctions.
Additional Information
Refer to the hardware user’s manual for the CPU Unit to which Units are connected for infor-
mation on the designing of the power supply for the CPU Rack.
The CPU Unit supplies the NX Unit power to the NX Units in the CPU Rack.
There are the following types of NX-series power supply-related Units other than CPU Unit.
Refer to NX-series catalogs or OMRON websites, or ask your OMRON representative for information
on the most recent lineup of NX Units.
