    • SAFETY PRECAUTIONS • (Always read these instructions before using this equipment.)

    Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The instructions given in this manual are concerned with this product. For the safety instructions of the programmable controller system, please read the user's manual of the CPU module to use. In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".

    ! DANGER

    CAUTION!

    Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

    Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

    Note that the ! CAUTION level may lead to a serious consequence according to the circumstances. Always follow the instructions of both levels because they are important to personal safety.

    Please save this manual to make it accessible when required and always forward it to the end user.

    [DESIGN PRECAUTION] ! DANGER

    • See Chapter 5 of this manual for each station's operating status when there is a communication error in the data link.

    • When performing the control of the PLC in operation (changing data) by connecting a personal computer, etc. to the intelligent function module or connecting peripheral devices to the CPU module, configure an interlock circuit in a sequence program so the safety of the overall system is always maintained. Before performing other controls of the PLC in operation (changing program and operation status (status control)), read this manual carefully and confirm if the overall safety is maintained. Especially, when this control is performed to a remote PC from an external device, troubles that have occurred on the PLC side may not be able to immediately be handled if there is a data communication error. Define a troubleshooting agreement between external devices and the PLC CPU for data communication error occurrences, as well as construct an interlock circuit in the sequence program.

  • A - 2 A - 2

    [DESIGN PRECAUTION] ! DANGER

    • Do not write data into the "system area" of the buffer memory of intelligent function modules. Also, do not output the "prohibited to use" signal as the output signal to an intelligent function module from the PLC CPU. Writing data into the "system area" or outputting a signal for "prohibited to use" may cause system malfunction in the PLC.

    • To specify the automatic refresh parameter, specify "Y" for the remote output RY refresh device. If a value other than "Y" (for example, M or L) is specified, the status of the device will remain as it was prior to the STOP operation when the CPU is stopped. See Section 4.4.10 for how to stop the data link.

    [DESIGN PRECAUTION] ! CAUTION

    • Do not bunch the control wires or communication cables with the main circuit or power wires, or install them close to each other. They should be installed 100mm(3.9inch) or more from each other. Not doing so could result in noise that may cause malfunction.

    [INSTALLATION PRECAUTIONS] ! CAUTION

    • Use the PLC in an environment that meets the general specifications contained in the CPU user's manual to use. Using this PLC in an environment outside the range of the general specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the product.

    • When installing the module, securely insert the module fixing tabs into the mounting holes of the base unit while pressing the installation lever located at the bottom of the module downward. Improper installation may result in malfunction, breakdown or dropping out of the module. Securely fix the module with screws if it is subject to vibration during use.

    • Tighten the screws within the range of specified torque. If the screws are loose, it may cause fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

    • Switch all phases of the external power supply off when mounting or removing the module. Not doing so may cause damage to the module.

    • Do not directly touch the conductive area or electronic components of the module. Doing so may cause malfunction or failure in the module.

  • A - 3 A - 3

    [WIRING PRECAUTIONS] ! CAUTION

    • When turning on the power and operating the module after installing is completed, always attach the terminal cover that comes with the product. There is a risk of malfunction if the terminal cover is not attached.

    • Tighten the terminal screws within the range of specified torque. If the terminal screws are loose, it may cause short circuits, or malfunction. If the terminal screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

    • Be careful not to let foreign matters such as sawdust or wire chips get inside the module. These may cause fires, failure or malfunction.

    • The top surface of the module is covered with protective film to prevent foreign objects such as cable offcuts from entering the module when wiring. Do not remove this film until the wiring is complete. Before operating the system, be sure to remove the film to provide adequate heat ventilation.

    • Use a dedicated cable as specified by the manufacturer for the CC-Link system. If a cable other than the one specified by the manufacturer is used, the performance of the CC-Link system cannot be guaranteed. Also, follow the specifications listed in Chapter 3 for the overall cable distance and the station-to-station cable length. If wiring is done other than as specified, accurate transmission of data cannot be guaranteed.

    • Be sure to fix communication cables or power supply cables leading from the module by placing them in the duct or clamping them. Cables not placed in the duct or without clamping may hang or shift, allowing them to be accidentally pulled, which may cause a module malfunction and cable damage.

    • When removing the communication cable or power supply cable from the module, do not pull the cable. When removing the cable with a connector, hold the connector on the side that is connected to the module. When removing the cable connected to the terminal block, first loosen the screws on the part that is connected to the terminal block. Pulling the cable that is still connected to the module may cause malfunction or damage to the module or cable.

  • A - 4 A - 4

    [STARTING AND MAINTENANCE PRECAUTIONS] ! CAUTION

    • Do not disassemble or modify each module. Doing so could cause failure, malfunction, injury or fire.

    • Switch all phases of the external power supply off when mounting or removing the module. Not doing so may cause failure or malfunction of the module.

    • Do not touch the connector while the power is on. Doing so may cause malfunction.

    • Switch all phases of the external power supply off when cleaning or retightening terminal screws and module installation screws. Not doing so may cause failure or malfunction of the module. If the screws are loose, it may cause fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damages to the screws and/or the module, resulting in fallout, short circuits or malfunction.

    • Always make sure to touch the grounded metal to discharge the electricity charged in the body, etc., before touching the module. Failure to do so may cause a failure or malfunctions of the module.

    [DISPOSAL PRECAUTIONS] ! CAUTION

    • When disposing of this product, treat it as industrial waste.
