• 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 NX bus connector and X
Bus connector.
• When you handle the Unit, be careful not to apply stress to the pins in the NX bus connector and X
Bus connector.
If the Unit is installed and the power supply is turned ON when the pins in the connector are de-
formed, contact failure may cause malfunctions.
• Mount a cover to the left end of the X Bus Unit to prevent foreign objects from entering. A short sig-
nal circuit or 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 ap-
proximately 10 mm. Make sure that the CPU Rack and connecting cables do not come into contact
with other devices.
