This catalog is a guide to help customers select the proper safety products. Observe the following items when choosing

products, select the right products for your devices or equipment, and develop a safety-related system to fully utilize product

functions.

Setting Up a Risk Assessment System

The items listed in this catalog must be used properly in terms of product location as well as product performance and

functionality. Part of the process of selecting and using these products should include the introduction and development of a

risk assessment system early in the design development stage to help identify potential dangers in your equipment that will

optimize safety product selection. A badly designed risk assessment system often results in poor choices when it comes to

safety products.

ISO 14121 Principles of Risk Assessment

Safety Policy

When developing a safety system for the devices and equipment that use safety products, make every effort to understand

and conform to the entire series of international and industrial standards available, such as the examples given below.

• Related International Standards:

ISO 12100 Basic Concepts, General Principles for Design

IEC 61508 Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems

Role of Safety Products

Safety products have functions and mechanisms that ensure safety as defined by standards. These functions and

mechanisms are designed to attain their full potential within safety-related systems. Make sure you fully understand all

functions and mechanisms, and use that understanding to develop systems that will ensure optimal usage.

• Related International Standards:

ISO 14119 Interlocking Devices Associated with Guards-Principles for Design and Selection

Installing Safety Products

Make sure that properly educated and trained engineers are selected to develop your safety-related system and to install

safety products in devices and equipment.

• Related International Standards:

ISO 12100 Basic Concepts, General Principles for Design

IEC 61508 Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems

Observing Laws and Regulations

Safety products should conform to pertinent laws, regulations, and standards, but make sure that they are used in

accordance with the laws, regulations, and standards of the country where the devices and equipment incorporating these

products are distributed.

• Related International Standards:

IEC 60204 Electrical Equipment of Machines

Observing Usage Precautions

Carefully read the specifications and precautions listed in this catalog for your product as well as all items in the Operating

Manual packed with the product to learn usage procedures that will optimize your choice. Any deviation from precautions

will lead to unexpected device or equipment failure not anticipated by safety-related systems or fire originating from

equipment failure.

Transferring Devices and Equipment

When transferring devices and equipment, be sure to keep one copy of the Operating Manual and pack another copy with

the device or equipment so the person receiving it will have no problem operating it.
