  • Page 2: Safety Precautions

    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] WARNING When there are communication problems with the data link, the communication problem station will enter the following condition. Build an interlock circuit into the sequence program that will make sure the system operates safely by using the communication state information. Not doing so could result in erroneous output or erroneous operation.
  • Page 4 [Installation Precautions] CAUTION Use the programmable controller in an environment that meets the general specificaitons contained in CPU module user’s manual. Using this programmable controller in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.
  • Page 5 [Wiring Precautions] WARNING Before installation or wiring, be sure to shut off all phases of the external power supply used by the system and the one for the network (A1SJ71QLP21S). Failure to do so may cause electric shocks or damage the product. CAUTION Always connect the FG terminals to the ground using class D (class 3) or higher grounding exclusively designed for programmable controller.
  • Page 6 [Startup and Maintenance Precautions] CAUTION Please read this manual thoroughly and confirm the safety before starting online operations (especially, program modifications, forced outputs, and operating status modifications), which are performed by connecting the GX Developer via the MELSECNET/10 network system to a running CPU module of other station.

    (6) Connect the cable connector and module connector securely until you hear a "click" sound. (7) Please wire IN/OUT of the connector for the cable correctly. Please do loopback test, the set confirmation test, and the bureau order confirmation test after wiring. It might be generated that a baton abnormal passing cannot be generated when miswiring and the downed bureau which cannot do the loopback of an arbitrary bureau do the row again even by the reclosing of the power supply.
