Sounds interesting. Typically, the UL recognition mark is used for components. >From UL's web site: "These are marks consumers rarely see because they are specifically used on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. The Component Recognition marking is found on a wide range of products, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment and thousands of other products."
If the product can be used standalone - with a mouse, keyboard and monitor, then I would've expected to see a listing mark. However, recognition can be applied to "some kinds of industrial control equipment" -perhaps in installations where such product is a 'component' of a larger system. But then you could also have UL evaluate the product as a 'listed accessory'. Perhaps the wrong mark was used on the label? But that would be picked-up during Follow-Up Services inspection . . . if the product was put through UL. A more established manufacturer would more likely to have had the product evaluated properly and the right mark applied. I would be more concerned if the manufacturer was 'more recently established' less aware, or more cavalier regarding product safety. John A. Juhasz GE Interlogix Fiber Options Div.

In 20 years, I've never seen this before but that's not saying much. Why would a mfr get a UL recognition approval for a commercial ITE style single phase 155-230vac computer style product but for that same product get the TUV "GS" mark? Mfr is a stateside company. Product to be used in restricted areas with trained personnel only. But, one that essentially anyone could buy. What's the advantage of getting such a mixed set of approvals? I would assume such a thing would normally get a Listing. Maybe turning the question around for our overseas friends - why would you get a GS mark for your product but only get UL recognition for an ITE computer product when it's normal to get a listing for such a product? And now I'm wondering if with such a device that there's some deviation within the testing as to cause the product to be GS accepted but not with a listing.
