 MSC achieves the following safety levels: SIL 3, SILCL 3, PL e, cat. 4, type 4 as per the
applicable standards. However the final SIL and PL safety categories for the applica-
tion are dependent on the number of safety components, their parameters and the
connections made, as per the risk analysis.

 Undertake a comprehensive risk analysis to determine the corresponding safety level
for the specific application based on the applicable standards.
 The programming/configuration of the MSC system is the sole responsibility of the
installer or the user.
 The system must be programmed/configured as per the application-specific risk
analysis and all applicable standards.
 After programming/configuration and installation of the MSC system and all related
devices, a complete application safety check must be undertaken (see "CHECKING the
system", page 75).
