Hi Neils, In IEC 61000-4-5: 2005, section 7.6 describes how to perform Surge to a shielded I/O cable, the pulse is applied to the shield and there are two methods depending on shield termination, also see figures 16 and 17. Regards, Charlie Martin

Both line/earth and line/line. In the E10 there is a reference to figure 10 of the standard for equipment where power and signal lines are identical, which is the case in my situation. Figure 10 of IEC 61000-4-5 1995 is test set-up for unshielded interconnection lines, so that makes some sense. But my cables are shielded, so my question is: Does anybody know it the test should be performed to the shield, or to the inner wires?
