Thanks Ari. IEC 61000-4-5 Surge - I can't use the mains CDN (which is internal) due to the limitations in the DC input (60VDC only). I am seriously looking into direct injection.
IEC 61000-4-4 Transients - Agree. I will use the capacitive clamp method. IEC 61000-4-6 Conducted RF - Based on the Coupling flowchart, I think I will go for the EM Clamp.

If no other instructions, use the mains coupler you have. 61000-4-4 fast transients: simply use the mains coupler or capacitive clamp 61000-4-6 RF imm: power line CDN. This seems simple, did I miss some specific problem you have?
