• Illustrations contained in this manual sometimes depict conditions without covers and safety shields 
for the purpose of showing the details. When you use this product, be sure to install the covers and 
shields as specified and use the product according to this manual.
• If the product has been stored for an extended period of time, contact your OMRON sales represen-
tative.
If the functions of safety products cannot attain their full potential, it will result in minor or moderate 
injury, or may result in serious injury or death. When building the system, observe the following warn-
ings and optimize safety product selection for your equipment and devices to ensure the integrity of the 
safety-related components.
 Setting Up a Risk Assessment System
The process of selecting these products should include the development and execution of a risk 
assessment system early in the design development stage to help identify potential dangers in your 
equipment and optimize safety product selection.
The following is an example of related international standards.
• ISO12100 General Principles for Design - Risk Assessment and Risk Reduction
 Protective Measure
When developing a safety system for the equipment and devices that use safety products, make 
every effort to understand and conform to the entire series of international and industry standards 
available, such as the examples given below.
The following are examples of related international standards.
• ISO12100 General Principles for Design - Risk Assessment and Risk Reduction
• IEC60204-1 Electrical Equipment of Machines - Part 1: General Requirements
• ISO13849-1, -2 Safety-related Parts of Control Systems
• ISO14119 Interlocking Devices Associated with Guards - Principles for Design and Selection
• IEC/TS 62046 Application of Protective Equipment to Detect the Presence of Persons
 Role of Safety Products
Safety products incorporate standardized safety functions and mechanisms, but the benefits of 
these functions and mechanisms are designed to attain their full potential only within properly 
designed safety-related systems. Make sure you fully understand all functions and mechanisms, 
and use that understanding to develop systems that will ensure optimal usage.
The following are examples of related international standards.
• ISO14119 Interlocking Devices Associated with Guards - Principles for Design and Selection
• ISO13857 Safety Distances to Prevent Hazard Zones being Reached by Upper and Lower Limbs
