• You must use power supplies with an output hold time of 10 ms or longer for the DC power sup-
plies that are connected as the Unit power supplies and I/O power supplies for the NX-series
Units.
• This is a Class A product (for industrial environments). In a residential environment, it may cause
radio interference. If radio interference occurs, the user may be required to take appropriate
measures.

Use a shield wire (2 conductors, twisted wire) to connect the High-speed Analog Input Units. The com-
patibility was confirmed in a condition that the shield wire was not connected. The compatibility was
also confirmed in a configuration where the I/O wiring was less than 30 m.
Conformance to UL and CSA Standards
Some NX-series products comply with UL and CSA standards.
If you use an NX-series product that complies with UL or CSA standards and the machinery or system
in which you use the NX-series product must also comply with the standards, refer to the
Instruction
Sheet
that is provided with the product. The
Instruction Sheet
provides the application conditions for
complying with the standards.
Conformance to Shipbuilding Standards
Some NX-series products comply with shipbuilding standards.
If you use an NX-series product that complies with shipbuilding standards and the machinery or sys-
tem in which you use the NX-series product must also comply with the standards, consult with your
OMRON representative. Application conditions are defined according to the installation location. Appli-
cation may not be possible for some installation locations.
For usage conditions for shipbuilding standards, refer to
Conformance to Shipping Standards
in the
user's manual for the CPU Unit or Communications Coupler Unit that the NX Units are connected to.
Note that the usage conditions are provided in the relevant user's manuals for Units whose conform-
ance to shipbuilding standards is confirmed.
