Conditions for Achieving Safety Class
The conditions for achieving the various safety classes are summarized in the table below.
Table 7- 11 PM-D F DC24V PROFIsafe: Conditions for SIL/Categories/PL
Condition Achievable SIL/Category/PL
Fail-safe motor starters are expanded with the expansion modules:
• Brake control xB3 and xB4
SIL2/Category 3/PLd
Power supply of:
• Exclusively fail-safe motor starters F-DS1e-x and F-RS1e-x
• Fail-safe frequency converters F-FU
• Fail-safe connection multipliers F-CM
• Fail-safe power/expansion modules PM-D F X1
Fail-safe motor starters are expanded with the expansion modules:
• Brake Control xB1 and xB2
SIL3/Category 4/PLe
Note
The safety classes SIL2/Category 3/PLd or SIL3/Category 4/PLe listed in the table above
can only be achieved with the modules specified in the "Condition" column. Configurations
with other modules (e.g. motor starter DS1-x/RS1x, DS1e-x/RS1e-x, DSS1e-x) are not
permitted for safety-related applications.
