  • Locations subject to temperatures or humidity outside the range specified in the specifications.
  • Locations subject to condensation as the result of severe changes in temperature.
  • Locations subject to corrosive or flammable gases.
  • Locations subject to dust (especially iron dust) or salts.
  • Locations subject to water, oil, or chemicals.
  • Locations subject to shock or vibration.

Take appropriate and sufficient countermeasures when installing systems in the following locations. Inappropriate and insufficient measures may result in malfunction.

  • Locations subject to static electricity or other forms of noise.
  • Locations subject to strong electromagnetic fields.
  • Locations subject to possible exposure to radioactivity.
  • Locations close to power supplies.

Installation/Mounting

  • Use the NE1A-SCPU02 within an enclosure with IP54 protection or higher of IEC/EN 60529.
  • Use DIN rail (TH35-7.5 according to IEC60715) for placing the NE1A-SCPU02 into the control board.
  • Mount the NE1A-SCPU02 to DIN rails with attachments (TYPE PFP-M, not incorporated to this product), not to drop out of rails by vibration etc.
  • Spacing should be available around the NE1A-SCPU02 at least 50mm from its top and bottom surfaces for ventilation and wiring.
  • This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.

  • After wiring is completed, be sure to remove label for wire clipping prevention on the NE1A-SCPU02 to enable heat to escape for proper cooling.

Power Supply Selection

Use DC power supply satisfying requirements below.

  • Secondary circuits of DC power supply is isolated from its primary circuit by double insulations or reinforced insulations.
  • DC power supply satisfies the requirement for class 2 circuits or limited voltage/current circuit stated in UL 508.
  • 20ms or over of the output hold time.
  • DC power supply that satisfies the requirements for SELV given in IEC/EN60950-1 or EN 50178.

Periodical Inspection and Maintenance

  • Disconnect the NE1A-SCPU02 from power supply when replacing. Devices connected to the NE1A-SCPU02 may operate unexpectedly.
  • Do not dismantle, repair, or modify the NE1A-SCPU02. It may lead to loss of its safety functions.
