[Installation Precautions]
 Use the programmable controller in an environment that meets the general specifications
contained in the user's manual of the CPU module to use.
Using this programmable controller in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, 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.
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.

Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Not doing so may cause damage to the module.
In the system where a CPU module supporting Online module change is used and on the
MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).
However, there are some restrictions on replaceable modules and the replacement procedures
are predetermined for each module.
For details, refer to the chapter of Online module change in this manual.

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 programmable controller.
There is a risk of electric shock or malfunction.

Use applicable solderless terminals and tighten with the specified torque. If any solderless spade
terminal is used, it may be disconnected when the terminal screw comes loose, resulting in
failure.
 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.
