Power Supply Precautions

DANGER
SHORT CIRCUIT, FIRE, OR UNINTENDED EQUIPMENT OPERATION
  • Install and fasten this product in an installation panel or cabinet prior to connecting power supply and communication lines.
  • Securely attach power cables to an installation panel or cabinet.
  • Avoid excessive force on the power cable.
Failure to follow these instructions will result in death or serious injury.

  • This product's power cord should not be bundled with or kept close to main circuit lines (high voltage, high current), power lines, or input/output lines, and their various systems should be kept separate. When power lines cannot be wired via a separate system, use shielded cables for input/output lines.

  • An independent DC power supply is recommended for this product. (The DC power supply should be located close to the product, with twisted pair cabling as short as possible.)

  • To increase noise resistance, attach a ferrite core to the power cable.

Power Supply Connections

  • Use the SELV (Safety Extra-Low Voltage) circuit and LIM (Limited Energy) circuit for DC input.
  • If the voltage variation is outside the prescribed range, connect a regulated power supply.
