NX-series Safety Control Unit User’s Manual (Z930)
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.
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.

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.
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 Persons
• IEC 62061 Functional Safety of Safety-related Electrical, Electronic and Programmable Electronic
Control Systems

tems
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.

Qualified engineers must develop your safety-related system and install safety products in devices and
equipment. Prior to machine commissioning verify through testing that the safety products works as
expected.
