ensure a correct angle for the cable arrangement when crimping the TWIN end sleeve so
that the cables are optimally arranged.

Safety standards for fail-safe motor starters
Fail-safe motor starters fulfill the following standards under certain conditions:
● PL e/Cat. 4 according to EN ISO 13849-1
● Safety Integrity Level SILCL3 acc. to IEC 62061
To fulfill both standards, lay cross-circuit proof and P-cross-circuit proof control cables from
the safe output of a sensor or F-DQ to the safe input of the motor starter, e.g. as a
separately sheathed cable or in a separate cable duct.
