2.1 Qualified Personnel for Working with Functional Safety

Only qualified personnel can install, configure, commission, maintain, and decommission functional safety features and functions.
Qualified personnel for working with functional safety features are qualified electrical engineers, or persons who have received
training from qualified electrical engineers, and are suitably experienced to operate devices, systems, plants, and machinery in ac-
cordance with the general standards and guidelines for safety technology.
Furthermore, they must:
• Be familiar with the basic regulations concerning health and safety/accident prevention.
• Have read and understood the safety guidelines given in this manual.
• Have a good knowledge of the generic and specialist standards applicable to the specific application.
Installers and system designers of power drive systems (safety-related) (PDS(SR)) are responsible for:
• Hazard and risk analysis of the application.
• The overall safety of the application.
• Identifying safety functions required and allocating SIL or PL to each of the functions, other subsystems, and the validity of sig-
nals and commands from them.
• Designing appropriate safety-related control systems, such as hardware, software, and parameterization.

2.2 General Safety Considerations

When installing or operating the AC drive, pay attention to the safety information given in the instructions. For more information
about safety guidelines for installation, see the product-specific safety guide that is included in the drive shipment. For more infor-
mation about safety guidelines for operating the drive, see the product-specific operating guide.
After installing the safety functions, perform a commissioning test.
A successful commissioning test is required after the initial installation, and after each change to the installation or application
involving functional safety.
-
If the commissioning test fails, safe operation cannot be guaranteed.
See 5 Commissioning for more information on performing the commissioning test.
RISK OF ELECTRIC SHOCK
The STO safety function does not provide electrical safety. The STO function itself is not sufficient to implement the Emergency-
Off function as defined by IEC 60204-1:2018. Using the STO function to implement Emergency-Off may lead to death or personal
injury.
-
Emergency-Off requires measures of electrical isolation, for example, by switching off mains via an extra contactor.
