[Design Precautions]
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
[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 programmable controller in an environment that meets the general specifications in the
user's manual for the CPU module used. Failure to do so may result in electric shock, fire,
malfunction, or damage to or deterioration of the product.
● To mount the module, while pressing the module mounting lever in the lower part of the module, fully
insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it
snaps into place. Incorrect mounting may cause malfunction, failure, or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the module
with a screw.
● Tighten the screws within the specified torque range. Undertightening can cause drop of the screw,
short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
[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.
