Engineering Information
Acceptance test
The machine manufacturer must carry out an acceptance test for the activated Safety Integrated functions (SI
functions) on the machine. This also applies to the STO and SS1 functions. During the acceptance test, all the limit
values entered for the enabled function must be exceeded to check and verify that the functions are working properly.
Each SI function must be tested and the results documented and signed in the acceptance certificate by an
authorized person. Authorized in this sense refers to a person who has the necessary technical training and
knowledge of the safety functions and is authorized by the machine manufacturer to carry out the test. The
acceptance certificate must be stored in the machine logbook.
Certificate
The Safe Torque Off and Safety Stop 1 functions are approved by an accredited body, in accordance with the
machine directive 98/37/EC, EN 60204-1 and category 3 of the EN 954-1 resp. ISO/FDIS 13849-1:2006, and also in
accordance with IEC 61508 SIL 2 as well as with performance level d of the ISO/FDIS 13849-1. The certificate
always refers to specific versions of hardware and firmware.
It is important to note that the certificate refers only to those components listed in the table on the previous page,
starting at the input terminals of the safety-integrated function. Additional circuitries inside and outside the cabinets
are not included.

Validity range of the certificate
For standard cabinet units G150, S150 and S120 Cabinet Modules option K82 is available, which consists of the
complete cable wiring inside the cabinet for all connections required in accordance with certified standards. Further
information can be found in the section "Option K82" of the chapter "Modular Cabinet Unit System SINAMICS S120
Cabinet Modules".
According to IEC 61508, IEC 62061 and ISO 13849-1 it is required to quantify the probability of failures for safety
functions in form of a PFH value (Probability of Failure per Hour). The PFH value of a safety function depends on the
safety concept of the drive unit, its hardware configuration and on the PFH values of additional components, which
are required for the safety function. For SINAMICS units PFH values are provided in dependency on the hardware
configuration (number of units, number of sensors, etc.). Thereby no differece is made between the individual
integrated safety functions.
A list of certified components and firmware versions as well as a list of the PFH values is available on request from
your local Siemens partners.
