[INSTALLATION PRECAUTIONS]
•
Use the PLC in an environment that meets the general specifications contained in the user's
manual of the CPU module to use.
Using this PLC in an environment outside the range of the general specifications may cause
electric shock, fire, malfunction, and damage to or deterioration of the product.
•
When installing the module, securely insert the module fixing tabs into the mounting holes of the
base unit while pressing the installation lever located at the bottom of the module downward.
Improper installation may result in malfunction, breakdown or the module coming loose and
dropping.
Securely fix the module with screws if it is subject to vibration during use.
•
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
•
Switch all phases of the external power supply off when mounting or removing the module.
Not doing so may cause damage to the module.
•
Do not directly touch the conductive area or electronic components of the module.
Doing so may cause malfunction or failure in the module.
[WIRING PRECAUTIONS]
•
Always ground the FG terminal for the PLC.
There is a risk of electric shock or malfunction.
•
When turning on the power and operating the module after wiring is completed, always attach
the terminal cover that comes with the product.
There is a risk of electric shock if the terminal cover is not attached.
•
Tighten the terminal screws within the range of specified torque.
If the terminal screws are loose, it may result in short circuits or malfunction.
If the terminal screws are tightened too much, it may cause damage to the screw and/or the
module, resulting in short circuits or malfunction.
•
Be careful not to let foreign matter such as sawdust or wire chips get inside the module.
They may cause fires, failure or malfunction.
•
The top surface of the module is covered with protective film to prevent foreign objects such as
cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate ventilation.
