Installation/Mounting
- Use the NE1A-SCPU01-V1 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-SCPU01-V1 into the control board.
- Mount the NE1A-SCPU01-V1 to DIN rails with attachments (TYPE PFP-M, not incorporated to this product), to prevent it from dropping out of rails due to vibration etc.
- Spacing should be available around the NE1A-SCPU01-V1 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.
Installation/Wiring
Use the following to wire external I/O devices to the NE1A-SCPU01-V1:
- Solid wire: 0.2 to 2.5 mm² (AWG24 to 12)
- Standard (Flexible) wire: 0.34 to 1.5 mm² (AWG22 to 16)
- Disconnect the NE1A-SCPU01-V1 from power supply when wiring. Devices connected to the NE1A-SCPU01-V1 may operate unexpectedly.
- Apply properly specified voltages to the NE1A-SCPU01-V1 inputs. Applying inappropriate DC voltage and any AC voltages causes the NE1A-SCPU01-V1 to fail.
- Be sure to separate the communication cable and the I/O cable from the high-voltage/current lines.
- Be cautious not to have fingers caught when attaching connectors to the plugs on the NE1A-SCPU01-V1.

- After wiring is completed, be sure to remove label for wire clipping prevention on the NE1A-SCPU01-V1 to enable heat to escape for proper cooling.
Power Supply Selection
Use a DC power supply satisfying the requirements below:
- Secondary circuits of the DC power supply are 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.

- Disconnect the NE1A-SCPU01-V1 from power supply when replacing. Devices connected to the NE1A-SCPU01-V1 may operate unexpectedly.
- Do not dismantle, repair, or modify the NE1A-SCPU01-V1. It may lead to loss of its safety functions.
Disposal
- Be cautious not to be injured when dismantling the NE1A-SCPU01-V1.
The above-mentioned is a part of directions. Please use it after reading the operation manual.
