Page 5 For a fail-safe circuit example, refer to "General Safety Requirements" in MELSEC iQ-R Module Configuration Manual. (4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an output circuit.
Page 6 [Design Precautions] WARNING ● Do not write any data to the "system area" and "write-protect area" of the buffer memory in the module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to each module.
Page 7 [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 8 [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 the included terminal cover to the module before turning it on for operation.
Page 9 For wiring, refer to MELSEC iQ-R Module Configuration Manual. ● For Ethernet cables to be used in the system, select the ones that meet the specifications in the user's manual for the module used.
Page 10 [Startup and Maintenance Precautions] CAUTION ● When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding.
Page 11 ● When disposing of this product, treat it as industrial waste. ● When disposing of batteries, separate them from other wastes according to the local regulations. For details on battery regulations in EU member states, refer to MELSEC iQ-R Module Configuration Manual.
