Safety Precautions
Refer to the “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”.
Wiring
Use one of the following wires to connect to the
P7SA-10F/10F-ND/14F/14F-ND.
Stranded wire: 0.75 to 1.5 mm2
Solid wire: 1.0 to 1.5 mm2
Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a
torque of 0.78 to 0.98 N·m.
Wire the terminals correctly with no mistakes in coil polarity,
otherwise the G7SA will not operate.
Cleaning
The G7SA is not of enclosed construction. Therefore, do not wash the
G7SA with water or detergent.

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.
PROGRAMMABLE PRODUCTS
OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
ERRORS AND OMISSIONS
The information in this document has been carefully checked and is believed to be accurate; however, no responsibility is assumed for clerical,
typographical, or proofreading errors, or omissions.
