Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):8 o' K# \+ w# ], ]
“OSM decision 01/8 requires markings on the product (e.g. "Use only power supplies listed in the user manual / user instruction." or “For applicable power supplies see user instruction”). Furthermore such sentences shall be in the languages acceptable to the country where the product will be used.0 M# \; H3 t, v3 E
We cannot assume that all people speak or understand English and therefore it is necessary to put nearly all languages of such relevant safety instructions on the product.
( w0 j8 c- ?) J' Q; t6 b& D* GThat cannot be a solution because many products are too small!”; G ?9 X8 X. W- D: s; @4 ?
OSM/EE-2007 agreed to use instead of such instructions (sentences) on the product, international accepted symbols like these both marks (ISO 7000-0434 and ISO 7000-1641):

* j9 Z# w& f4 _/ TIt may be considered that the Decision 99/2, requiring marking of manufacturer and model of the power supply on the product, is too stringent in light of sub clause 1.7.2./ o+ I9 Q6 J4 J1 \" S! q/ c; V$ ]
Decision: This decision replaces 01/8 with the amended text in red:& c8 k2 }) x% O: W
A Class III equipment with an enclosure made of HB material and using a non-special connector for the a.c./d.c. input has to have a marking stating the following: "Use only power supplies listed in the user instructions"

In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.
# U: M6 g1 ^# Y" r6 _4 u) QAs an alternative to the text on the product, it is acceptable to use both the symbols ISO 7000-0434 and ISO 7000-1641. The book alone is also sufficient (ISO 7000-1641).
