Dear Treggers, RE: T1 service safety classification in USA/Canada
This is probably an easy question for those of you in the US. I want to confirm the safety status of the T1 service offered in the USA / Canada. Specifically when applying UL 1950 Amd.3 to a piece of Terminal Equipment. Probably because there are now the issues of SELV, TNV-1, TNV-2 and TNV-3 I am trying to understand if the service is either TNV or SELV. To further complicate matters I am anticipating there to be a differnt classifaction for the point of provision, i.e. DSU/CSU scenario ? Am I making a meal of this ? Can someone put me right, please! (or perhaps provide me with the working voltage of the abopve scenarios) Many thanks in advance for your advice. Edward Fitzgerald European Technology Services (UK)
