3-4 ControlLogix System HardwareRecommendations forSystem Hardware UseUsers must consider the recommendations listed below when usingSIL2-certified ControlLogix hardware:ChassisWhen installing ControlLogix chassis, follow the information providedin the product documentation listed in the Related ControlLogixHardware Documentation section on page 3-5.Power SuppliesUsers must consider these recommendations when using SIL2-certifiedControlLogix power supplies:• When installing ControlLogix power supplies, follow theinformation provided in the product documentation listed in theRelated ControlLogix Hardware Documentation section onpage 3-5.• A non-redundant power supply can be used if it meets theuser-defined PFD criteria.• For high availability SIL2 applications, the redundant powersupply is recommended.• It is recommended that the solid state fault relay on each powersupply be wired from an appropriate voltage source to an inputpoint in ControlLogix so the user can detect and display a powersupply fault.Publication 1756-RM001B-EN-P - October 2003
