Precautions for Safe Use

Handle with care

Do not drop the NE1A-SCPU01-EIP to the ground or subject it to excessive vibration or mechanical shocks. The NE1A-SCPU01-EIP may be damaged and may not function properly.

Installation and storage environment

Do not use or store the NE1A-SCPU01-EIP in any of the following locations:

Locations subject to direct sunlight.
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-SCPU01-EIP 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-EIP into the control board.
Mount the NE1A-SCPU01-EIP 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-EIP at least 5mm from its side and 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-EIP:
- Solid wire: 0.2 to 2.5mm² AWG24 to 12
- Standard (Flexible) wire: 0.34 to 1.5mm² AWG22 to 16
Disconnect the NE1A-SCPU01-EIP from power supply when wiring. Devices connected to NE1A-SCPU01-EIP may operate unexpectedly.
Apply properly specified voltages to the NE1A-SCPU01-EIP inputs. Applying inappropriate DC voltage and any AC voltages causes the NE1A-SCPU01-EIP 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-EIP.
Mount screw of DeviceNet Connector and I/O Connector correctly. (0.25-0.3N-m)
Incorrect wiring may lead to loss of safety function. Wire conductors correctly and verify the operation of the NE1A-SCPU01-EIP before commissioning the system in which NE1A-SCPU01-EIP is incorporated.
After wiring is completed, be sure to remove label for wire clipping prevention on the NE1A-SCPU01-EIP to enable heat to escape for proper cooling.

Power Supply Selection

Use DC power supply satisfying requirements below:

Secondary circuits of 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.

Periodical Inspection and Maintenance

Disconnect the NE1A-SCPU01-EIP from power supply when replacing. Devices connected to the NE1A-SCPU01-EIP may operate unexpectedly.
Do not dismantle, repair, or modify the NE1A-SCPU01-EIP. It may lead to loss of its safety functions.
