OMRON declares that NE1A-SCPU02 is in conformity with the requirements of the following EU 
Directives:

EMC Directive:2014/30/EU

In case that a safety output is configured as “Safety Pulse Test”, while this output is in an ON state, the pulsed 
off signal(pulse width:580µs) is output continuously for fault diagnosis. Confirm response time of device 
connected to safety outputs so the device does not malfunction due to this off pulse.

Do not drop the NE1A-SCPU02 to the ground or excessive vibration or mechanical shocks. The NE1A-SCPU02 
may be damaged and may not function properly.

Precautions for Safe Use

• 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.

• Use the following to wire external I/O devices to the NE1A-SCPU02.

• Disconnect the NE1A-SCPU02 from power supply when wiring. Devices connected to NE1A-SCPU02 may 

operate unexpectedly.

• Apply properly specified voltages to the NE1A-SCPU02 inputs. Applying inappropriate DC voltage and any AC 

voltages cause the NE1A-SCPU02 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 your fingers caught when attaching connectors to the plugs on the NE1A-SCPU02.
• 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-SCPU02 before commissioning the system in which NE1A-SCPU02 is incorporated.

• 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.

• 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.

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.

• 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.
