CAUTION

• Be careful not to let any foreign matter such as wire chips get inside the module.
They may cause fire, as well as breakdowns and malfunctions of the module.
• Never disassemble or modify the module.
This may cause breakdowns, malfunctions, injuries or fire.
• When attaching or removing the base module and all expansion module special
blocks, make sure to cut all external power supplies.
Failure to do so may cause the module to breakdown or malfunction.
• Tighten the terminal screws using the specified torque.
If the terminal screws are loose, it may cause the module to short-circuit,
malfunction or fall off.
Tightening the terminal screws excessively may damage the screws and/or the
module and cause the module to short-circuit, malfunction or fall off.
• Do not directly touch the conducting parts and electronic parts of the module.
This may cause the module to malfunction or fail.
• When disposing of this product, treat it as industrial waste.
• A protective sheet is pasted on the upper part of the module in order to prevent
foreign matter such as wire chips to get inside the module while wiring.
Do not remove this protective sheet during wiring work.
However, be sure to remove the protective sheet before operating the module to
allow heat radiation during operation.
• Before performing control operations (especially data modifications, program
modifications and operating-status modifications) on the PLC in operation, be sure
to confirm the safety.
• For basic module status control (remote RUN/STOP and similar controls) previous
parameter settings should normally be set to open. If these conditions are not met,
after a remote STOP, the communication line is closed from another node and
cannot be re-opened, so remote RUN cannot start.
