No exemptions I know of dependent on where a cable goes. Lightning signal is applied common mode so whether or not a differential mode signal is active or connected or not doesn¹t matter: signal is applied to entire bundle.
Pin testing may have to be performed with cited relay in either state.

Does DO-160G Lightning Induced Transients Cable Bundle Test have to be applied to all an Equipment¹s external cables including those that are connected to a separate equipment but are not directly electrically connected or bonded to the Aircraft platform? 2. In other words is Cable Bundle Test applicable to external cables or only those which directly interface with the Aircraft Platform? 3. Finally if all the external cables have to be tested, is there any exemptions for example if the external cable connections are normally disconnected by relays in the equipment and only very intermittently connected to the separate equipment for a very short period of time? Any help will be gratefully appreciated. Please feel free to reply to me directly at [email protected] instead of via the EMC-PTSC server if you prefer.
