Page 6: Selection Of Product And Implications
3 Selection of product and implications The choice of surge protection component is made according to the location, signal type, signal level and operational or maintenance considerations for the safety instrumented function rather than any safety aspect of the surge components themselves. See the previous comments regarding the nature of surge protection in relation to functional safety applications. - Page 7 SD range surge suppression devices Failure rate (FIT) Failure mode SD07/16/ SD16/32/ SDyyR/X (i) SD07z3 (ii) SDRTD 32/55 55z3 (ii) Connected signal not affected 23.9 14.9 22.0 22.0 21.1 Connected signal interrupted 14.5 14.5 20.1 17 .8 20.1 Errors in connected signal Correct operation (failures have no effect) 51.4 32.4...

Page 8: Emc
4.1 EMC The surge protection devices are designed for operation in normal industrial electromagnetic environment but, to support good practice, modules should be mounted without being subjected to undue conducted or radiated interference, see Appendix A for applicable standards and levels. Any maintenance or other testing activity should only be conducted when the field loop is not in service, to avoid any possibility of introducing a transient change in the field signal. -
