during operation.
• The HMI is a general purpose product. It is a system component and is used in conjunction with other items of industrial equipment such as PLC's. Loop Controllers,
Adjustable Speed Drives, etc.
• A detailed system analysis and job safety analysis should be performed by the system designer or system integrator before including the HMI unit in any new or existing system. Consult your OMRON representative for options availability and for
application specific system integration information if required.
• The product may be used to control an adjustable speed drive connected to high
voltage sources and rotating machinery that is inherently dangerous if not operated
safely. Interlock all energy sources, hazardous locations, and guards in order to
restrict the exposure of personnel to hazards. The adjustable speed drive may start
the motor without warning. Signs on the equipment installation must be posted to
this effect. A familiarity with auto-restart settings is a requirement when controlling
adjustable speed drives. Failure of external or ancillary components may cause
intermittent system operation, i.e., the system may start the motor without warning
or may not stop on command. Improperly designed or improperly installed system
interlocks and permissives may render a motor unable to start or stop on command.

conditions (i.e., wind, rain, snow, etc.).
• Never dispose electrical components via incineration. Contact your state
environmental agency for details on disposal of electrical components,
batteries and packaging in your area.
1-7 Conformance to EC Directives
1-7-1 Applicable directives
• EMC (ElectroMagnetic Compatibility) Directives
• Low-voltage directive
1-7-2 Concepts
OMRON units complying with EC Directives also conform to related product
standards making them easier to incorporate in other units or machines. The
actual products have been checked for conformity to product standards.
Whether the products conform to the standards in the system used by the
customer, however, must be checked by the customer.
Product related performance of OMRON units complying with EC Directives
will vary depending on the configuration, wiring, and other conditions of the
equipment or control panel in which OMRON devices are installed. The
customer must, therefore, perf orm final checks to confirm that units and the
overall system conforms to product standards.
A Declaration of Conformity for the NQ-Series can be requested at your
nearest OMRON representative.
1-7-3 Conformance to EC Directives
NQ-Series should be installed as follows, for the complete configuration to
meet the EC directives:
1 The units are designed for installation in panels. All units must be installed
in control panels.
2 Use reinforced insulation or double insulation for the DC power supplies
used for the communication power supply, internal circuit power supply,
and the I/O power supplies.
3 The NQ-Series meets the generic emission standard. However as EMC
performance can vary in the final installation, additional measures may be
required to meet the standards. It should therefore be verified that the
overall machine or device also meets the relevant standards. You must
therefore confirm that EC directives are met for the overall machine or
device, particularly for the radiated emission requirement (10 m).
4 This is a class A product. It may cause radio interference in residential
areas, in which case the user ma y be requ ired to take adequat e meas ures
to reduce interference.
