[Design Precautions]
Do not bunch the wires of external devices or communication cables together with the main circuit or
power lines, or install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause malfunctions.
Select the external devices to be connected to the CC-Link Safety remote I/O module, considering
the maximum inrush current with reference to the CC-Link Safety System Remote I/O Module User's
Manual.
[Installation Precautions]
Use a safety programmable controller in the environment that meets the general specifications
described in the QSCPU User's Manual (Hardware Design, Maintenance and Inspection).
Using this programmable controller in an environment outside the range of the general specifications
could result in electric shock, fire, erroneous operation, and damage to or deterioration of the
product.
Make sure to fix CC-Link Safety remote I/O module with a DIN rail or mounting screws and tighten
the screws with the specified torque.
If the screws are too loose, it may cause a drop of the screw or module.
Overtightening may cause a drop due to the damage of the screw or module.
Do not directly touch the module's conductive parts or electronic components.
Doing so may cause malfunctions or a failure.
[Wiring Precautions]
Be sure to shut off all phases of the external supply power used by the system before wiring.
Not completely turning off all power could result in electric shock or damage to the product.
When energizing or operating the module after installation or wiring, be sure to close the attached
terminal cover.
Not doing so may result in electric shock.
