Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):' N: y& @* C, e$ [5 U7 ?9 N+ b
“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.8 a& O. m. b3 K$ M# s5 ]
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.2 r* k' e: N7 F) M" r
That cannot be a solution because many products are too small!”
/ o, o2 `/ l. q9 J X* e3 H6 T; XOSM/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):
@7 O9 O+ }: _; z0 n, gLater it was confirmed by TC108/MT2 that the book only can be used as an alternative. See explanatory notes below. Based on this it is proposed to revise decision 01/8 as amended with red text under the decision below.0 h5 K" H) g( V W6 ^ s8 e5 B
It 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.% N9 b% {5 q+ {1 \5 S8 B
Decision: This decision replaces 01/8 with the amended text in red:
: u1 N' Z% V# B" u8 WA 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./ p5 n8 s: ~+ h+ g3 b* s5 Y
As 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).
