Re: [PSES] To earth or not to earth......
Hi Bostjan / Ted, Thanks for the information. The pluggable type A equipment in question has a VDR + GDT in series in the PSU. Mains cord connection is Line, Neutral and Earth with earth terminating to the chassis inside the unit. There is also has a provision for a permanently connected earth conductor (external earth screw in chassis). The question is does the unit have to be permanently connected to earth? Or does just providing the provision for a permanent connection meet the requirement? Thanks, Chris. On 5 March 2015 at 14:13, Ted Eckert ted.eck...@microsoft.com wrote: Hello Chris, Your equipment is required to have a provision for a permanently connected earthing conductor. Section 1.5.9.4 gives you three options. ·If your equipment has no permanent connections, it must be Pluggable Type B. Since you have already described your product as Pluggable Type A, this option isn’t available. ·Your equipment can have a permanent mains connection. Again, since you have Pluggable Type A, you can’t use this option. ·This leaves the third option of providing a provision for a permanently connected earthing conductor along with providing instructions on its proper use. It is not prohibited from having equipment with a permanent earthing connection yet pluggable line connections. This is an unusual and somewhat impractical construction, but it is allowed. It’s not all that different from the Japanese Class 01 plug. In Japan, grounded outlets are uncommon. Most residential and commercial outlets are NEMA 1-15 with just line and neutral. There is a strange plug in Japan that is allowed under Japanese national differences to IEC 60950-1. The Class 01 plug http://www.quail.com/P-2013.098/Power-Cord--Quail-Pn-2013098--25m-125mm3-Vctf-Black-Nacc-Jis-8303-Japan-With-Ground-Lead-To-Roj.aspx has the line and neutral blades, but it also has a ground wire coming off of it with a fork or ring lug. It isn’t exactly what would be required on your equipment, but it does show that such constructions are used in Japan.

Re: product modifications by the end user
Chris, I'm not sure about EN60065, but in EN60950 the user is always considered to be unqualified personnel and therefore does not know what they are exposing themselves to. If you invite a user to remove a cover from a unit (even if you have told them to disconnect the mains) the whole of the unit becomes user accessible by definition of the standard and must be safe even when powered. The user should not be exposed to any hazardous energy / voltages i.e. all circuits should be SELV. Maybe you should ask the bright marketing person to have a go. If he survives then it is OK.

In the process not only would the victim be exposed to hazardous voltages (if the product was still connected to the mains) but he/she would also have to wire up mains connections. There would also be a possibility that critical insulation would be disturbed. Apart from telling them that they were mad and suggesting that someone could be killed or seriously injured, would there be any black and white legislation that you could use to help bin this idea?

Re: Conducted Emissions on Telecom Ports
Pryor, Unfortunately, I don't think the definition is in question. It specifically states, that for the purposes of the standard, LANs are to be considered as telecomms ports as per section 3.6. It probably would have been less ambiguous if the standard defined Telecomms ports as Ports which are intended to be connected to the telecomms network OR LANs OR similar networks. As far as enforcement goes this will not change from the current method of enforcing compliance, primarily via the end user requesting DoCs and the relevent test data to back this document up. I believe the requirement goes back to a test that was performed under either VDE 0805 or 0806 (it was a long time ago that I had to perform the test). It was specifically aimed at unscreened cables over a certain length being placed in cable ducts and their impact on adjacent telecomms cables (if anybody remebers StarLan this was the product I was involved in).
