Qualified Personnel for Working with Functional Safety

2.1
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 accordance with
the general standards and guidelines for safety technology.
Furthermore, they must:
Be familiar with the basic regulations concerning health and safety/accident prevention.
l
Have read and understood the safety guidelines given in this guide.
l
Have a good knowledge of the generic and specialist standards applicable to the specific application.
l
Installers and system integrators of systems incorporating power drive systems (safety-related) are responsible for:
Hazard and risk analysis of the application.
l
The overall safety of the application.
l
Identifying safety functions required and allocating SIL or PL to each of the functions, other subsystems, and the validity of signals
l
and commands from them.
Designing appropriate safety-related control systems, such as hardware, software, and parameterization.
l

General Safety Considerations

2.2
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 information about
safety guidelines for operating the drive, see the product-specific guides.
COMMISSIONING TEST
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.
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
l
contactor.
