Precautions for Correct Use
Storage and Installation
• Follow the instructions in this manual to correctly perform installation.
• Do not operate or store the Controller in the following locations. Doing so may result in burning, in
operation stopping, or in malfunction.
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 re-
sult in malfunction, in operation stopping, or in burning.
Mounting
• When you install the Unit, be careful not to touch or bump the pins in the X Bus connector.
• When you handle the Unit, be careful not to apply stress to the pins in the X Bus connector. If the
Unit is installed and the power supply is turned ON when the pins in the X Bus connector are de-
formed, contact failure may cause malfunctions.
• Attach a cover to the left end of the X Bus Unit to prevent entry of foreign objects. Signal short-cir-
cuit or contact failure may cause malfunctions.
• If you use DIN Track Insulation Spacers to install a CPU Rack, the height will be increased by ap-
proximately 10 mm. Make sure that the CPU Rack and connecting cables do not come into contact
with other devices.
Wiring
• 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.
