Warnings
Serious injury may possibly occur due to loss of required safety functions.
When building the system, observe the following warnings 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 execu-
tion of a risk assessment system early in the design development stage to help identify
potential dangers in your equipment and optimize safety product selection.

Protective Measure
When developing a safety system for the equipment and devices that use safety prod-
ucts, make every effort to understand and conform to the entire series of international
and industry standards available, such as the examples given below
.
Related International Standards:
• ISO 12100 General Principles for Design - Risk Assessment and Risk Reduction
• IEC 60204-1 Electrical Equipment of Machines - Part 1: General Requirements
• ISO 13849-1, -2 Safety-related Parts of Control Systems
• ISO 14119 Interlocking Devices Associated with Guards - Principles for Design and
Selection
• IEC/TS 62046 Application of Protective Equipment to Detect the Presence of Per-
sons
• IEC 62061 Functional Safety of Safety-related Electrical, Electronic and Programma-
ble Electronic Control Systems
• IEC 61508 Functional Safety of Electrical/Electronic/Programmable Electronic Safe-
ty-related Systems
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.
