The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
  • Page 15 Safety Precautions Warning WARNING During Power Supply Do not touch the terminal section while power is ON. Electric shock may occur. Do not attempt to take any Unit apart. In particular, high-voltage parts are present in Units that supply power while power is sup- plied or immediately after power is turned OFF.
  • Page 16 Safety Precautions Voltage and Current Inputs Make sure that the voltages and currents that are input to the Units and slaves are within the specified ranges. Inputting voltages or currents that are outside of the specified ranges may cause accidents or fire.
  • Page 17 Safety Precautions Online Editing Execute online editing only after confirming that no adverse effects will be caused by devia- tions in the timing of I/O. If you perform online editing, the task execution time may exceed the task period, I/O may not be refreshed with external devices, input signals may not be read, and output timing may change.

  • Page 18: Precautions For Safe Use

    Precautions for Safe Use Precautions for Safe Use Transporting • When transporting any Unit, use the special packing box for it. Also, do not subject the Unit to excessive vibration or shock during transportation. • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit malfunction or burning.
  • Page 19 Precautions for Safe Use • Do not write on an NX Unit with ink within the restricted region that is shown in the following figure. Also do not get this area dirty. When the Unit is installed or removed, ink or dirt may adhere to the pins in the NX bus connector, which may result in malfunctions in the CPU Rack or the Slave Termi- nal.
  • Page 20 Precautions for Safe Use • Do not press the flat-blade screwdriver straight into the release holes on a screwless clamping termi- nal block. Doing so may break the terminal block. • When you insert a flat-blade screwdriver into a release hole on a screwless clamping terminal block, press it down with a force of 30N or less.
  • Page 21 Precautions for Safe Use Actual Operation • Before you start operation, always register the NX Units that are connected to the Communications Coupler Unit in the host communications master as the Unit configuration information. • Check the user program, data, and parameter settings for proper execution before you use them for actual operation.
  • Page 22 Precautions for Safe Use Using Communications Interface Units • Always check polarity before connecting RS-422A/485 cables. The polarity of the SDA/SDB and RDA/RDB terminals and signals are reversed for some remote devices. NX-series Communications Interface Units User’s Manual (W540)

  • Page 23: Precautions For Correct Use

    Precautions for Correct Use Precautions for Correct Use Storage, Mounting, and Wiring • Follow the instructions in this manual to correctly perform installation and wiring. • Do not operate or store the Units in the following locations.
