Safety; Introduction; Validity And Responsibility - Universal Robots UR3/CB3 User Manual

1.1 Introduction

This chapter contains important safety information, which must be read and under-
stood by the integrator of UR robots before the robot is powered on for the first time.
The first subsections in this chapter are more general and the later subsections contain
more specific engineering data relevant for setting up and programming the robot.
It is essential that all assembly instructions and guidance provided in other chapters
and parts of this manual are observed and followed.
Chapter 2 describes and defines safety-related functions particularly relevant for col-
laborative applications. Instructions and guidance provided in that chapter and in
section 1.7 is particularly important.
Special attention shall be paid to text associated with warning symbols.

1.2 Validity and Responsibility

The information does not cover how to design, install and operate a complete robot
application, nor does it cover all peripheral equipment that can influence the safety of
the complete system. The complete system must be designed and installed in accor-
dance with the safety requirements set forth in the standards and regulations of the
country where the robot is installed.
The integrators of UR robots are responsible for ensuring that the applicable safety
laws and regulations in the country concerned are observed and that any significant
hazards in the complete robot application are eliminated.
This includes, but is not limited to:
• Making a risk assessment for the complete system;
• Interfacing other machines and additional safety devices if defined by the risk
• Setting up the appropriate safety settings in the software;
• Ensuring that the user will not modify any safety measures;
• Validating that the total system is designed and installed correctly;
• Specifying instructions for use;
• Marking the robot installation with relevant signs and contact information of the
• Collecting all documentation in a technical file; including the risk assessment and
