- Page 2 SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. In this manual, the safety precautions are classified into two levels: "...
- Page 3 [Design Precautions] CAUTION When laying the control wire or communication cable, do not bundle with or place near main circuit or power line. Keep them at least 100 mm (3.94 in.) away from such cables. Noise may cause erroneous operation. [Installation Precautions] CAUTION Use the PLC in the environment given in the general specifications section of...
- Page 4 [Wiring Precautions] CAUTION Do not connect the AUI cable when the module installation station's power is turned on. Perform correct pressure-displacement, crimp-contact or soldering for external wire connections using the tools specified by the manufactures. Incorrect connection may cause short circuits, fire or malfunction. Attach connector to the module securely.
- Page 5 [Startup and Maintenance Precautions] WARNING Do not touch the terminals while the electricity is on. Doing so could cause erroneous operation. Make sure to switch all phases of the external power supply off before cleaning or re-tightening screws. If you do not switch off the external power supply, it will cause failure or erroneous operation of the module.
- Page 6 [Operating Precautions] WARNING Do not write data in the “system area” in the buffer memory of the special function module. Also, of the output signals directed to the special function module from the PLC CPU, do not output (switch on) the signals that are “use-prohibited”. If data is written to the ”system area”...
