Re: Static Discharge - An issue to be added to the technical issues list
Dieter, thank you for the input. I will record the following as the first
additional technical issue to be added to our issues list:
Decide if there is a need to specify a discharge path for the portential
on the cable. If the answer is yes, decide if it should be part of the
requirements or an informative annex. Then complete the work for
incorporating the information in the draft.
Best regards,
