Ron,
As a product developer, my major concern was getting the Lexmark Marknet XLe
approved worldwide. From my viewpoint HAR approval of the jumper cord was
equivalent to a bunch of individual country approvals. But Feller is still the
only manufacturer that I know of that makes IEC-320 jumper co

Regardless of the input the output of the DC/AC inverter must comply with
2.4 of UL 1950 if it could be touched by the user. If it doesn't meet the
requirement then it must be enclosed in a fire enclosure and provided a
barrier to prevent service personal from accidentally touching it.

conceivable that this message got to you without using telco equipment, at
least in the traditional sense. It use to be that digital signals were sent

I'm going to throw a monkey wrench into this discussion. Why do you need HAR
cordage? It is not mandatory to use it in Europe or the EU. Also HAR cordage
can only be manufactured by suppliers in those countries that have accepted the
HAR agreement and use HD 21 or HD 22 as their National Standar

Richard is correct. However, according to Industry Canada's web site, ICES-003
is now at Issue 3 dated Nov 22, 1997. Also, the suggested wording can be found
in the Annex.

Brian,
I'm not sure that I agree with you on your TCF statement. Our TCF's reference
Harmonized documents, when these change I'm expecting that we will have to
update our TCF for what ever changes are introduced.
You don't agree?
Derek.

Help!!!
The low frequency radiated emissions uses a Rod antenna with a
counterpoise,
1, Is the counterpoise 0.5 or 0.6m square?
2, Is there a standard method of connecting the counterpoise to the
earth plane?
Many thanks for your assistance

For digital devices, I believe the Industry Canada specification is now
ICES-003 Issue 3 (November 22, 1997), which references Canadian Standards
Association Standard C108.8-M1983, "Electromagnetic Emissions from Data
Processing Equipment and Electronic Office Machines".

Erik,
My understanding is that your second scenario is correct. Therefore
after July 1, 2001 you must either meet 50082-1:1997 or 50024:1998.
(Whichever is more applicable of course) As of now you can apply
EN 50082-1:1997 or EN 50024:1998 as they are both published in the

Thanks Tania for the response. I believe your response shows that there is
a need to open dialogue to work out these issues. I will attempt to answer
your questions.

Jim,
Thank you for giving us an opportunity to respond.
It would have been very helpful if the telco providers referenced in your
e-mail were more specific as to why they cannot "harmonize" with UL1950
requirements. By specific, I mean paragraph by paragraph. But let me guess

We occasionally solve "wiggly monitor" problems for customers in the

I think that the direction and intent of the commission on the use of the OJ
in identifying harmonized standards is pretty clear. I do not believe that
this should be causing such a conundrum. The OJ lists standards as being
relevant to the LVD, and I would say those standards are the harmonized
