Do not use or store the NE1A-series Controller 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 measures 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 and Mounting

• Use the NE1A-series Controller within an enclosure with IP54 protection
or higher according to IEC/EN 60529.

• Use DIN rail (TH35-7.5/TH35-15 according to IEC 60715) to install the
NE1A-series Controller into the control panel. Mount the NE1A-series
Controller to the DIN rail using PFP-M End Plates (not included with the

Additional Precautions According to UL 1604 5

• Disconnect the NE1A-series Controller from the power supply before
starting wiring. Devices connected to the NE1A-series Controller may
operate unexpectedly.

• Properly apply the specified voltage to the NE1A-series Controller inputs.
Applying an inappropriate DC voltage or any AC voltage will cause the
NE1A-series Controller to fail.

• Be sure to separate the communications cables and I/O cables from near
high-voltage/high-current lines.

• Be cautious not to get your fingers caught when attaching connectors to
the plugs on the NE1A-series Controller.

• Tighten the DeviceNet connector screws correctly (0.25 to 0.3 N·m).

• Incorrect wiring may lead to loss of safety functions. Wire conductors cor­rectly and verify the operation of the NE1A-series Controller before using
the system in which the NE1A-series Controller is incorporated.

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

■ Power Supply Selection

Use a DC power supply satisfying the following requirements.

• The secondary circuits of the DC power supply must be isolated from the
primary circuit by double insulation or reinforced insulation.

• The DC power supply must satisfy the requirements for class 2 circuits or
limited voltage/current circuits given in UL 508.

• The output hold time must be 20 ms or longer.

■ Periodic Inspections and Maintenance

• Disconnect the NE1A-series Controller from the power supply before
replacing the Controller. Devices connected to the NE1A-series Controller
may operate unexpectedly.

• Do not disassemble, repair, or modify the NE1A-series Controller. Doing
so may lead to loss of safety functions.

■ Disposal

• Be cautions not to injure yourself when dismantling the NE1A-series Con­troller.

5 Additional Precautions According to UL 1604

The NE1A-series Controller is suitable for use in Class I, Div. 2, Group A, B,
C, D or Non-Hazardous Location Only.

WARNING - Explosion Hazard - Substitution of Components May Impair Suit­ability For Class I, Div. 2.

7 Unit Versions of NE1A-series Controllers

Checking the Unit Version

A “unit version” has been introduced to manage NE1A-series Safety Network
Controllers according to differences in functionality accompanying Unit
upgrades even though the model numbers are the same. The unit version can
be checked on the product itself or using the Network Configurator.

Note The Network Configurator maintains a revision number to manage device

functions for DeviceNet and EtherNet/IP. Refer to Checking the Unit Version
with the Network Configurator on page xxiv for the relationship between
NE1A-series Controller unit versions and the revisions.

Checking the Unit Version on the Product Nameplate

The unit version (Ver. @.@) is listed near the lot number on the nameplate of
the products for which unit versions are being managed, as shown below.

• Unit versions for the NE1A-SCPU01 and NE1A-SCPU02 start at unit ver­sion 1.0.

• Controllers that do not have a unit version listed on the label are called
Pre-Ver. 1.0 Controllers.

• Unit versions for the NE1A-SCPU01-EIP and NE1A-SCPU02-EIP start at
unit version 1.0.
