[Security Precautions]
● To maintain the security (confidentiality, integrity, and availability) of the programmable controller and
the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other
cyberattacks from external devices via the network, take appropriate measures such as firewalls,
virtual private networks (VPNs), and antivirus solutions.
[Installation Precautions]
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
● Use the module in an environment that meets the general specifications in this manual. Failure to do
so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
● Securely fix the module with a DIN rail.
● Securely connect the cable connectors. Poor contact may cause malfunction.
[Wiring Precautions]
● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
[Wiring Precautions]
● Tighten any unused terminal screws within the specified torque range. Undertightening can cause a
short circuit due to contact with a solderless terminal.
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when a terminal block screw comes loose,
resulting in failure.
● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
● Tighten the terminal block screws within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, fire, or malfunction.
