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.
Improper installation may result in malfunction, breakdown or the module
coming loose and dropping. After mounting the module to the base unit
securely hold the module with module fixing bracket.
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.
Do not directly touch the conductive area or electronic components of the
module.
Doing so may cause malfunction or failure in the module.
CAUTION
Always ground the FG terminal for the programmable controller.
There is a risk of electric shock or malfunction.
Be careful not to let foreign matters such as sawdust or wire chips get inside
the module.
These 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
heat ventilation.
