Application Considerations
BASIC CONSIDERATIONS
At OMRON, we are constantly working to improve the quality and reliability of our products. Protective Relays, however, use
semiconductors, which are prone to malfunction. Be sure to use Protective Relays within their rated values. Use the Protective
Relays only in systems that are designed with redundancies, flame protection, countermeasures to prevent operation errors,
and other countermeasures to prevent accidents involving human life or fires.
SELECTION OF PRODUCTS
The applications, illustrations, and charts shown in this catalog are intended solely for purposes of example. Because there are
many variables and requirements associated with any particular application, the final design can only be made in view of the
specific parameters of each application. OMRON does not assume responsibility or liability for actual use based upon the
examples shown in this catalog. Please consult one of our sales offices if you have any doubts or questions concerning your
application.
In particular, the following criteria must always be considered in the selection, application, and installation of control equipment.
•
Type of power supply
•
Voltage rating (max. and min.)
•
Current rating (max. and min.)
•
Power rating (max. and min.)
•
Suitability of frequency of operating controls
•
Effects of component failure (mechanical and/or electrical)
•
Ambient temperature of Protective Relays (Be aware that Protective Relays generate heat.)
•
Mounted state
SUITABILITY FOR USE
OMRON shall not be responsible for conformity with any standards, codes, or regulations that apply to the combination of
products in the customer’s application or use of the products.
At the customer’s request, OMRON will provide applicable third party certification documents identifying ratings and limitations
of use that apply to the products. This information by itself is not sufficient for a complete determination of the suitability of the
products in combination with the end product, machine, system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not intended to be an
exhaustive list of all possible uses of the products, nor is it intended to imply that the uses listed may be suitable for the products.
•
Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in
this catalog.
•
Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement
machines, vehicles, safety equipment, and installations subject to separate industry or government regulations.
•
Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON
PRODUCTS ARE PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR
SYSTEM.
