[DESIGN PRECAUTIONS] CAUTION
!Do not bunch the control wires or communication cables with the main circuit or power
wires, or install them close to each other.
They should be installed 100mm (3.9inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
[INSTALLATION PRECAUTIONS]
CAUTION
!Use the PLC in an environment that meets the general specifications contained in the
CPU user's manual 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
dropping out of the module.
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 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] CAUTION
!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 malfunction 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 cause fallout, 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 fallout, short circuits 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.
!Be sure to fix communication cables or power supply cables leading from the module
by placing them in the duct or clamping them.
Cables not placed in the duct or without clamping may hang or shift, allowing them to
be accidentally pulled, which may cause a module malfunction and cable damage.
!When removing the communication cable or power supply cable from the module, do
not pull the cable. When removing the cable with a connector, hold the connector on
the side that is connected to the module.
When removing the cable connected to the terminal block, first loosen the screws on
the part that is connected to the terminal block. Pulling the cable that is still connected
to the module may cause malfunction or damage to the module or cable.
