Precautions for Correct Use
NX-series CPU Unit Hardware User’s Manual (W535)
Precautions for Correct Use
• Follow the instructions in this manual to correctly perform installation.
• Do not operate or store the Controller in the following locations. Operation may stop or malfunctions
may occur.
a) Locations subject to direct sunlight
b) Locations subject to temperatures or humidity outside the range specified in the specifications
c) Locations subject to condensation as the result of severe changes in temperature
d) Locations subject to corrosive or flammable gases
e) Locations subject to dust (especially iron dust) or salts
f) Locations subject to exposure to water, oil, or chemicals
g) Locations subject to shock or vibration
• Take appropriate and sufficient countermeasures when installing the Controller in the following loca-
tions.
a) Locations subject to strong, high-frequency noise
b) Locations subject to static electricity or other forms of noise
c) Locations subject to strong electromagnetic fields
d) Locations subject to possible exposure to radioactivity
e) 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.
• Install the Controller away from sources of heat and ensure proper ventilation. Not doing so may
result in malfunction, in operation stopping, or in burning.
• When you install the Unit, be careful not to touch or bump the pins in the NX bus connector.
• When you handle the Unit, be careful not to apply stress to the pins in the NX bus connector.
If the Unit is installed and the power supply is turned ON when the pins in the NX bus connector are
deformed, contact failure may cause malfunctions.
• Always mount an End Cover to the end of the CPU Rack to protect the last Unit on the CPU Rack.
Not mounting the End Cover may result in malfunction or failure of the CPU Unit.
• After you mount the Unit, always secure it with End Plates at both sides. If you do not secure it, the
Unit may be damaged or malfunction.
• If you use DIN Track Insulation Spacers to install a CPU Rack, the height will be increased by approx-
imately 10 mm. Make sure that the CPU Rack and connecting cables do not come into contact with
other devices.
