• Do not allow wire clippings, shavings, or other foreign material to enter any Unit. Otherwise, Unit
burning, failure, or malfunction may occur. Cover the Units or take other suitable countermeasures,
especially during wiring work.
• For EtherCAT and EtherNet/IP, use the connection methods and cables that are specified in the
NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual
(Cat. No. W505) and the
NJ/NX-series
CPU Unit Built-in EtherNet/IP Port User’s Manual
(Cat. No. W506). Otherwise, communications may
be faulty.
• Use the rated power supply voltage for the Units that supply power. Take appropriate measures to
ensure that the specified power with the rated voltage and frequency is supplied in places where the
power supply is unstable.
• Make sure that the current capacity of the wire is sufficient. Otherwise, excessive heat may be gen-
erated. When cross-wiring terminals, the total current for all the terminals will flow in the wire. When
wiring cross-overs, make sure that the current capacity of each of the wires is not exceeded.
• If you use reed switches for the input contacts for AC Input Units, use switches with a current ca-
pacity of 1 A or greater.
If reed switches with smaller allowable currents are used, the contacts may fuse due to surge cur-
rents.
Operation
• Confirm the device output hold configuration before you change the operating mode of the CPU Unit
or execute the download.
• Take safety measures for the controlled system as well.
Error Processing
• In applications that use the results of instructions that read the error status, consider the affect on
the system when errors are detected and program error processing accordingly. For example, even
the detection of a minor error, such as Battery replacement during operation, can affect the system
depending on how the user program is written.
• If you change the event level of a Controller error, the output status when the error occurs may also
change. Confirm safety before use.
Restoring and Automatically Transferring Data
• When you edit the restore command file or the automatic transfer command file, do not change any-
thing in the file except for the “yes” and “no” specifications for the selectable data groups. If you
change anything else in the file, the Controller may perform unexpected operation when you restore
or automatically transfer the data.
• To prevent an unexpected restoration, set to enter the password for each execution before the re-
store operation.
