plant, and machinery in accordance with the general standards and guidelines for safe-
ty technology.
• Are familiar with the basic regulations concerning health and safety/accident preven-
tion.
• Have read and understood the safety guidelines given in this section and also the in-
structions given in the general operating instructions of the stepper motor.
• Have a good knowledge of the generic and specialist standards applicable to the spe-
cific application.
Users of power drive systems (safety related) (PDS(SR)) are responsible for:
• Hazard and risk analysis of the application.
• Identifying safety functions required and allocating SIL or PLr to each of the functions.
• Other subsystems and the validity of signals and commands from them.
• Designing appropriate safety-related control systems (hardware, software, parame-
terization, and so on).
Protective measures
• Only qualified and skilled personnel is allowed to install and commission safety engi-

• Check the ingress protection (IP) level of the motor before installation in wet, humid
environments -
• Ensure short-circuit protection of the STO cable between the motor and the external
safety device according to ISO 13849-2 table D.4.
• When external forces influence the motor axis (for example suspended loads), extra
measures (for example a safety holding brake) are required to eliminate hazards.
3.2.2 Safety precautions
CAUTION
After installation of STO, perform a commissioning test as specified in chapter
missioning
and after each change to the safety installation. In case that the test of STO fails:
