Certain Precautions on Specifications and Use

1. Suitability of Use. Omron Companies shall not be responsible for conformity

with any standards, codes or regulations which apply to the combination of the

Product in the Buyer’s application or use of the Product. At Buyer’s request,

Omron will provide applicable third party certification documents identifying

ratings and limitations of use which apply to the Product. This information by

itself is not sufficient for a complete determination of the suitability of the Prod-

uct in combination with the end product, machine, system, or other application

or use. Buyer shall be solely responsible for determining appropriateness of

the particular Product with respect to Buyer’s application, product or system.

Buyer shall take application responsibility in all cases but the following is a

non-exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical

interference, or conditions or uses not described in this document.

(ii) Use in consumer products or any use in significant quantities.

(iii) Energy control systems, combustion systems, railroad systems, aviation

systems, medical equipment, amusement machines, vehicles, safety equip-

ment, and installations subject to separate industry or government regulations.

(iv) Systems, machines and equipment that could present a risk to life or prop-

erty. Please know and observe all prohibitions of use applicable to this Prod-

uct.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS

RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT

ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO

ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-

ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE

OVERALL EQUIPMENT OR SYSTEM.

2. Programmable Products. Omron Companies shall not be responsible for the

user’s programming of a programmable Product, or any consequence thereof.

3. Performance Data. Data presented in Omron Company websites, catalogs

and other materials is provided as a guide for the user in determining suitabil-

ity and does not constitute a warranty. It may represent the result of Omron’s

test conditions, and the user must correlate it to actual application require-

ments. Actual performance is subject to the Omron’s Warranty and Limitations

of Liability.

4. Change in Specifications. Product specifications and accessories may be

changed at any time based on improvements and other reasons. It is our prac-

tice to change part numbers when published ratings or features are changed,

or when significant construction changes are made. However, some specifica-

tions of the Product may be changed without any notice. When in doubt, spe-

cial part numbers may be assigned to fix or establish key specifications for

your application. Please consult with your Omron’s representative at any time

to confirm actual specifications of purchased Product.

5. Errors and Omissions. Information presented by Omron Companies has been

checked and is believed to be accurate; however, no responsibility is assumed

for clerical, typographical or proofreading errors or omissions.
