Introduction

Safety Certification

Safety Concept
This section describes the safety performance level concept and how the
PowerFlex™ 7000 drives can meet the requirements for SIL CL3, Cat. 3, or PLe
applications.
The PowerFlex 7000 drive safety option is certified for use in safety
applications up to and including SIL 3 according to EN 61800-5-2, IEC
61508, and EN 62061, PLe, and Cat. 3 according to ISO 13849-1. Safety
requirements are based on the standards current at the time of certification.
The TÜV Rheinland group has approved the PowerFlex 7000 drive safety
option for use in safety-related applications where the de-energized state is
considered to be the safe state. All of the examples in this manual are based on
achieving de-energization as the safe state for typical Machine Safety and
Emergency Shutdown (ESD) systems.

Important Safety Considerations

The system user is responsible for:
• the set-up, safety rating, and validation of any sensors or actuators
connected to the system.
• completing a system-level risk assessment and reassessing the system any
time a change is made.
• certification of the system to the desired safety performance level.
• project management and proof testing.
• programming the application software and the safety option
configurations in accordance with the information in this manual.
• access control to the system.
• analyzing all configuration settings and choosing the proper setting to
achieve the required safety rating.
IMPORTANT When applying Functional Safety, restrict access to qualified, authorized
personnel who are trained and experienced.
IMPORTANT This safety function may be used where power removal is required to prevent
unexpected start-up.
