Precautions for Correct Use
NX-series EtherNet/IP Coupler Unit User’s Manual (W536)
Precautions for Correct Use
• Follow the instructions in this manual to correctly perform installation and wiring.
• Do not operate or store the Units in the following locations. Doing so may result in malfunction, in
operation stopping, or in burning.
Locations subject to direct sunlight
Locations subject to temperatures or humidity outside the range specified in the specifications
Locations subject to condensation as the result of severe changes in temperature
Locations subject to corrosive or flammable gases
Locations subject to dust (especially iron dust) or salts
Locations subject to exposure to water, oil, or chemicals
Locations subject to shock or vibration
• Take appropriate and sufficient countermeasures during installation in the following locations.
Locations subject to strong, high-frequency noise
Locations subject to static electricity or other forms of noise
Locations subject to strong electromagnetic fields
Locations subject to possible exposure to radioactivity
Locations close to power lines
• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any
static build-up.
• 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.
• Install the Units away from sources of heat and ensure proper ventilation. Not doing so may result in
malfunction, in operation stopping, or in burning.
• Do not allow foreign matter to enter the openings in the Unit. Doing so may result in Unit burning,
electric shock, or failure.
• Use the EtherNet/IP connection methods and applicable cables that are specified in this manual and
in the CS and CJ Series EtherNet/IP Units Operation Manual (Cat. No. W465). Otherwise, communi-
cations may be faulty.
• If you change the event level of an error, the output status when the error occurs may also change.
Confirm safety before you change an event level.
• Do not turn OFF the power supply while data is being transferred.
• Do not turn OFF the power supply while parameters are being written to the Communications Cou-
pler Unit or NX Units.
Do not disconnect the EtherNet/IP communications cables during operation. The outputs will become
unstable.
