The precautions presented in this manual are concerned with this product only. For programmable
controller system safety precautions, refer to the user’s manual of the CPU module used.
In this manual, the safety precautions are ranked as “WARNING” and “CAUTION.”
WARNING
Indicates
that
incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
CAUTION

[DESIGN PRECAUTIONS]
CAUTION
Provide a safety circuit outside the programmable controller to ensure that the overall system
operates safely in the event of an error in the external power supply or failure of the
programmable controller itself. Failure to do so results in the risk of erroneous output and
malfunction, resulting in module failure.
Configure the circuitry so that the external power supply is activated after the power supply of the
programmable controller itself. Activating the external power supply first results in the risk of
erroneous output and malfunction, resulting in module failure.
When installing the RFID interface module and amplifier/antenna cables, do not bundle the
cables with or install the cables close to the main circuit, power lines, or the like. Be sure to
separate the cables and lines by about 100mm or more. Failure to do so will cause noise,
resulting in malfunction.
