  • Page 3: 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. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the MELSEC iQ-R Module Configuration Manual.
  • Page 4 [Design Precautions] WARNING ● Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.
  • Page 5 [Design Precautions] WARNING ● Especially, when a remote programmable controller is controlled by an external device, immediate action cannot be taken if a problem occurs in the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.
  • Page 6 [Design Precautions] WARNING ● If a stop error occurs in the CPU module, the operating status of the DP-Master is as follows. In a redundant system, however, the operation is the same as when "CPU Error Output Mode Setting" is set to "Hold" regardless of its setting value. (1) When "CPU Error Output Mode Setting"...
  • Page 7 [Design Precautions] CAUTION ● Do not install the control lines or communication cables together with the main circuit lines or power cables. Doing so may result in malfunction due to electromagnetic interference. Keep a distance of 100mm or more between those cables. ●...
  • Page 8 [Installation Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in electric shock or cause the module to fail or malfunction. [Installation Precautions] CAUTION ●...
  • Page 9 [Wiring Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before installation and wiring. Failure to do so may result in electric shock or cause the module to fail or malfunction. ● After installation and wiring, attach a blank cover module (RG60) to each empty slot and an included extension connector protective cover to the unused extension cable connector before powering on the system for operation.
  • Page 10 [Wiring Precautions] CAUTION ● Tighten the terminal screws or connector screws within the specified torque range. Undertightening can cause drop of the screw, short circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or malfunction. ●...
  • Page 11 [Startup and Maintenance Precautions] WARNING ● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. ● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Also, do not expose it to liquid or strong shock. Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
  • Page 12 [Startup and Maintenance Precautions] CAUTION ● Do not drop or apply shock to the battery to be installed in the module. Doing so may damage the battery, causing the battery fluid to leak inside the battery. If the battery is dropped or any shock is applied to it, dispose of it without using.
