Here is my interpretation: since the requirements of the EMC Directive are
integral part of the essential requirements under the RTTE Directive, a
single declaration to the RTTE Directive should be sufficient. But if the

Peter,
For your equipment special consideration of transient levels is needed.
Refer to annex G of 60950. If you power the pole mounted equipment from
overhead lines as do streetlights, you are likely to be overvoltage
category IV which might mean mains transient levels of 4 or 6 KV.

Hi Kevin,
I am inclined to side with the regulatory authority. If you have a

Kevin,
Council Directive 99/5/EC does call out directives 73/23/EEC and 89/336/EEC.
Since some customers are not aware of the linkage, listing all three
directives on the DofC avoids having to 'educate the customer'. Either way,
standards applied will tell the story.
