2.1 Configuring ET 200S with Fail-Safe Modules
Configuration Rules for Fail-Safe Voltage Groups
The "Assignment of Power Modules to Electronic Modules/Motor Starters and Safety Class"
table presents all of the fail-safe and standard power and electronic modules that you can
use in a voltage group.
Configuration with Fail-Safe Motor Starters and Frequency Converters
Use a PM-D F DC24V PROFIsafe for the selective shutdown of:
• fail-safe motor starters (F-MS) F-DS1e-x, F-RS1e-x
• SINAMICS fail-safe frequency converters (F-FU) with ICU24(F)
• fail-safe F-CM connection multipliers
• PM-D F X1 fail-safe power/expansion modules.
The PM-D F DC24V PROFIsafe cannot supply other motor starters (for example
DS1-x/RS1-x, DS1e-x/RS1e-x, DSS1e-x).
The fail-safe motor starters can be expanded:
• up to safety class (safety integrity level) AK6/SIL3/Category 4 with the Brake Control xB1,
• up to safety class (safety integrity level) AK4/SIL2/Category 3 with the Brake Control xB3,
Example of a Configuration with Fail-Safe Motor Starters
The following figure shows an example of an ET 200S configuration with two fail-safe voltage
groups. The first voltage group contains fail-safe motor starters and a connection multiplier.
This configuration achieves safety class (safety integrity level) AK6/SIL3/Category 4.
