Wiring

  • Make sure that the power supply is off while wiring.
  • Verify that the supply voltage variation is within the rating.
  • Ensure that an isolation transformer is utilized for the DC power supply. If an autotransformer is utilized, the main body or power supply may be damaged.
  • If the used power supply generates a surge, connect a surge absorber to the power supply to absorb the surge.
  • In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
  • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
  • Damage or burnout may result in case of short circuit of load or miswiring.
  • Make a cable length as short as possible to lessen noise pickup.

Others

  • Our products have been developed / produced for industrial use only.
  • Avoid using a product where there is excessive vapor, dust or corrosive gas, or in a place where it could be exposed directly to water or chemicals.
  • Take care that the sensor does not come in direct contact with water, oil, grease or organic solvents, such as, thinner, etc.
  • Do not use in an environment containing inflammable or explosive gases.
  • Never disassemble or modify the product.
