[Installation Precautions]
• Use the programmable controller in an environment that meets the general specifications shown
in "Safety Guidelines", the manual supplied with the CPU module or head module.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
• To interconnect modules, engage the respective connectors and securely lock the module joint
levers.
Incorrect interconnection may cause malfunction, failure, and drop of the module.
• Do not directly touch any conductive part and electronic components of the module.
Doing so can cause malfunction or failure of the module.
[Wiring Precautions]
• Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
• After installation and wiring, attach the included terminal cover to the product before turning it on
for operation.
Failure to do so may result in electric shock.
[Wiring Precautions]
• 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 screw on the terminal
block comes loose, resulting in failure.
• Do not install the control lines or communication cables together with the main circuit lines or
power cables.
Failure to do so may result in malfunction due to noise.
• Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or
cables or malfunction due to poor contact.
• Tighten the terminal block screw 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.
• When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable with connector, hold the connector part of the cable.
For the cable connected to the terminal block, loosen the terminal block screws.
Pulling the cable connected to the module may result in malfunction and damage to the module
or cable.
