[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 PLC in the environment that meets the general specifications described in the QSCPU
User's Manual (Hardware Design, Maintenance and Inspection).
Using this PLC 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.
While pressing the installation lever located at the bottom of module, insert the module fixing tab into
the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing hole as
a supporting point.
Incorrect loading of the module can cause a failure or drop.
Secure the module to the base unit with screws.
Tighten the screw in the specified torque range.
If the screws are too loose, it may cause a drop of the screw or module.
Over tightening may cause a drop due to the damage of the screw or module.
Make sure to fix the 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.
Over tightening may cause a drop due to the damage of the screw or module.
Completely turn off the external supply power used in the system before mounting or removing the
module.
Not doing so could result in damage to the product.
Do not directly touch the module's conductive parts or electronic components.
Doing so may cause malfunctions or a failure.
