[Installation Precautions]
CAUTION
• 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 located in the lower part of the
module, fully insert the module fixing projection(s) in the hole(s) in the base unit and press the
module until it snaps into place.
Incorrect interconnection 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 screw 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.
• When using an extension cable, connect it to the extension cable connector of the base unit
securely.
Check the connection for looseness.
Poor contact may cause incorrect input or output.
• When using a memory card, fully insert it into the memory card slot.
Check that it is inserted completely.
Poor contact may cause malfunction.
• Shut off the external power supply for the system in all phases before mounting or removing the
module.
Failure to do so may result in damage to the product.
• Do not touch the module during turning on electricity and immediately after power supply
interception. There is fear of a burn.
• 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]
WARNING
• Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in electric shock or damage to the product.
• After wiring, attach the included terminal cover to the module before turning it on for operation.
Failure to do so may result in electric shock.
