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.
Line protection
The line protection of the SIMATIC ET 200SP motor starter is provided for the motor
outgoing feeder cable when the following condition is met:
The cross-section of the motor outgoing feeder cable must be dimensioned for the load
ratios of the motor and for the cable-laying method.
Comply with national regulations. The user is responsible for the correct selection and
dimensioning of the motor connection cable to DIN VDE 0100 and DIN VDE 0298-4 and/or
UL 508.
The conductor protection for the incoming feeders must be ensured by the owner of the
installation depending on the cross-section.
Permissible cable temperature
Note
Permissible cable temperature
The minimum permissible cable temperature must be 30 °C higher than the ambient
temperature of the ET 200SP (example: at an ambient temperature of 60 °C, a connection
conductor must be dimensioned for a temperature range of at least 90 °C).
You should specify other connection types and material requirements based on the electrical
characteristics of the circuits you use and the installation environment.
