RE: CE Marking Passive devices
Yes, there is a reason. There is a Toy Directive which (I'm on unfamiliar ground here) deals mostly with child safety. As such, some really passive hunks of plastic (i.e. Barbie Dolls (and Ken Dolls, for gender equality) come with CE marks on them. When it comes to children, any piece of material, no matter how passive is suspected as a hazard. My understanding is that the Toy Directive requires testing to prove that toys don't present physical (i.e choking, strangulation) or chemical (i.e. toxicity) hazards to our most precious citizens. My guess is that the toys that you are thinking of are completely exempt from the EMC or Low Voltage Directives that most of us deal with. Their CE marking is probably based on the Toy Directive or some other non-electrical safety requirement. It's a whole different question than the one posed by Courtland regarding passive electrical components, which, I assume; aren't toys. Actually, along a different line of reasoning, (that doesn't apply to toys) I wonder if some manufacturers are CE marking items which are exempt from all of the New Approach directives? I wonder if they are affixing the CE mark as if to say, we're exempt from everything, so we must be CE approved? It could just be a way of ensuring that their goods don't get bottled up in customs.

Re: CE Marking Passive devices
There are a number of CE marking directives including 88/378/EEC Toy Safety. Before toys may be shipped into Europe they must be tested for safety and marked with the CE mark if they comply. The relevant standard is EN 71, Safety of Toys; Specification for Mechanical and Physical Properties. EN 50088 is a separate standard that covers the electrical safety of toys.

RE: SAFETY LISTING
Multiple Listing can also be done. The only advantage under that scheme beyond the one listed below. Is that none of the paperwork or the id number ever refers to the OEM. It really looks like the multiple Listee is the designer manufacturer. It costs a few hundred to do so, but some clients prefer that. Usually, UL will allow you to make the marking changes at the time you request the Multiple Listee because its a paper change only. So time isn't an issue, just the cost.

RE: SAFETY LISTING
Courtland - If Customer 'DEF' doesn't mind your file number on the Listing label you can ask UL to use your file number instead of your company's name to identify the manufacturer. It is a minor report revision that UL has done many times before. It saves the trouble and time of going through the M/L process and cost. The upside is that if you have other customers that wish to sell your products under their name, you can do so without notifying UL.

RE: SAFETY LISTING
Courtland, When we get a product listed we only use our part number for the listing as a way to identify the product, we do not use a product name. That way so long as the part number does not change the Listing will still be valid no matter what product name is on the unit. We even put variables in the part number such as 510-1000-XXX-XX when we get the Listing. This allows us to replace the X's with any alphanumeric characters. By doing this we are able to make changes to parts that do not affect the Listing and have a unique part number for each different unit. These are typically items such as changes to SELV circuitry, painting the unit a different color, putting a customer's name and/or emblem on the unit, etc. We also have some customers that assign their own part number to our products in order to resell it. In that case we include their part number on the label under the heading of P/N and include our part number under the heading of M/N which stands for Manufacturer's Number. This satisfies the requirement of being able to identify the item by the manufacturer's part number or name.

Re: SAFETY LISTING
Hi Courtland, First some observations: UL only grants rights to use UL marks. Other labs can test to UL standards, but they would grant their own marks. UL has Listed Recognized Component other certifications, but not approval. In UL terms, Multiple Listing ML is where company X (Basic Listee) shares certification (but not control of the file) with company Y (Multiple Listee) model numbers can be same or different between companies there is an initial annual fee. As an option to ML, many companies use what is called File Number ID, where Basic Listee marks their UL File Number (E*) on the product to identify them, and puts company Y's name/logo on the product also. If the model number must change, put the Basic model number out of the way company Y's model # in bigger print prominently - no cost/no wait. If the Basic Listee wants to add an alternate model # (DEF) for marketing purposes, or for changes that do not affect safety, there would be a one-time cost (~U$600) for revising the Product Covered part of the report. I encourage my clients to use wildcards in their model number structure to allow for expansion without revising reports. Example: Today's new model is BELCHFIRE 2000 series. There are two versions which do affect safety those will be identified by the 2nd character (2100, 2200). The remaining 3rd 4th characters can be cosmetic software versions, allowing many combinations without updating the report. The Product Covered would read: Model 2XYY, where X is 1 or 2 and Y is any number, letter, or blank. You can also say may be followed by suffixes to cover an infinite possibility. All above remarks apply only to UL. I hope this helps.

RE: SAFETY LISTING
The product displays the name of the manufacturer and the model number. The name of the manufacturer may be changed at will without amending the UL report if the file number is listed near the UL Listing mark. However, if you wish to change the model number, then the UL report must be amended or a multiple listing used.

Re: TNV to Earth Insulation Requirement
Dear All, Assume you have equipment with external power earthed (Class 1) power supply with an earthed appliance inlet for conenction to the mains. The power supply output is connected to a dc unit with a TNV-2 interface with no separation to SELV. The dc unit has a earth stud for connection of an external earthing conductor. All exemptions for basic insulation in Table 19 is applied. My questions is: can the stud on the dc unit serve as my permanent connection to earth? UL1950/EN 60 950 Table 19 condition 2 specifies that the installation instructions specify that the protective earthing terminal shall have a permanent connection to earth. Is the stud the protective earthing terminal? What is the definition of protective earth terminal? From my understanding, protective earthing terminal is associated with the supply conductors and therefore the appliance inlet earthing terminal is in this case the terminal which must now be changed to have a permanent connection to earth. Is this assumption correct or can the stud on the dc unit serve as the permanent means for connection to the supply? If stud is OK, what is the min. size required?

Hi Dave: This topic seems to generate a lot of confusion and controversy, since most telecom equipment that the test labs see is subject to the isolation Many test labs seem to be unaware that the isolation requirements can be waived if certain conditions are met. However, UL 1950 does have provisions for certain types of equipment to not For example, central office equipment and large PBXs typically do not have isolation between TNV and SELV/ground. The requirements for isolation appear in several clauses in UL 1950 (6.2.1.2, To qualify for the exemptions, it is necessary to step through each clause and show compliance In general, though, equipment which has a permanently connected earth ground can usually For clause 6.3.3 that you mentioned, the permanent ground exemption can be found in clause 6.3.3.2. If your equipment qualifies for the exemptions from having isolation, there should be no requirement for a hipot test between your TNV circuits and If you plan to exercise the exemptions, I suggest that you review your rationale ahead of time with your test lab, before they try to hipot your equipment. The requirements in EN 60950 are pretty much the same as UL 1950, except that Norway and Sweden have additional requirements for the exemption that can be These requirements call for permanent connection or This may or may not affect your product if the input is strictly -48 VDC.

Re: EFT DC blocking capacitor question
Sorry this is a little late, but it is Schaffner's official response to the recent question from Antonio Cinquino Re: EFT DC blocking capacitor on Dec 5th. {Posted by Tony O'Hara 12/11/2000, LARCTEC Marketing, Colorado] Re: EFT DC blocking capacitor question from Antonio Cinquino To the EMC Dicussion group, I believe that using a 33nF cap in series with the generator as indicated by Schaffner is the correct way to apply EFT pulses for mains and power ports. Every diagram in the IEC 1000-4-4 standard shows 33nF capacitors which are external to the EFT generator. The relevant paragraphs from the EFT standard are listed below. In addition, it is important to note that according to Section 7.3.2, if the capacitive clamp cannot be used for I/O and data ports, discrete 100pf caps are used instead of the 33nF caps. IEC 1000-4-4 Section 6.2 Coupling/decoupling network for a AC/DC mains supply port describes the CDN for AC and DC mains ports and the circuit diagram is shown in Figure 4. The text and diagram show a 33nf coupling capacitor in series with each mains connection. Section 7.2.2 Methods of coupling the test voltage to the EUT, Power supply ports and Figures 8 and 10 show the 33nF cap in series with the generator as well. This section covers conditions where direct injection test must be applied. Section 7.3.1 Test on power supply ports and on protective earth terminals states that If AC/DC blocking capacitors are necessary their capacitance shall be 33nF. This section also refers to Figure 10 where the caps are shown in series with the generator. And finally, to clear the air, all Schaffner burst generators incorporate DC bocking capacitors with the mains and direct outputs.

RE: Application of CE Mark
Cyril, CE marking the packaging is hassle free transportation of goods within Europe. As you say, this will prevent the toll gate officials from tampering your packs. If your packaging has CE marks and also a copy of DOC (preferrably in a plastic bag affixed to your packaging)the officials have no right to open your packs to verify compliance. This means that your packaging remains intact and your products remain safe.
