  • Page 19: Warnings

    Safety Precautions Warnings 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 supplied or immediately after power is turned OFF.
  • Page 20 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 acci- dents or fire.

  • Page 21: Cautions

    Safety Precautions Cautions Caution Wiring When you connect a computer or other peripheral device to a Communications Coupler Unit that has a non-isolated DC power supply, either ground the 0-V side of the external power supply (i.e. Unit power supply) or do not ground it at all. If the peripheral devices are grounded incorrectly, the external power supply (i.e.

  • Page 22: 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 23 Precautions for Safe Use Restricted region (shaded portion) • For the installation orientations in the following figure, support the cables, e.g., with a duct, so that the End Plate on the bottom is not subjected to the weight of the cables. The weight of the cables may cause the bottom End Plate to slide downward so that the Slave Terminal is no longer secured to the DIN Track, which may result in malfunctions.
  • Page 24 Precautions for Safe Use • If you use reed switches for the input contacts for AC Input Units, use switches with an allowable current of 1 A or greater. If the capacity of the reed switches is too low, inrush current may fuse the contacts.
