Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
, p3 {$ U' a7 z0 N6 G“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.
3 _9 n4 N. y( U3 G" V' {; ^ tWe 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.
/ u6 G) P2 @' K) ?That cannot be a solution because many products are too small!”) B" V+ _' P Y' E
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):
" Q) @6 v4 t* p6 U% O$ r; Y Z0 qLater 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.
[9 C; l7 y( u. cIt 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 1.7.2.5 Y& K# A4 a" x
Decision: This decision replaces 01/8 with the amended text in red:0 }# O- \- u4 E1 f
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"$ k% m* ?# h/ y1 e

The user instructions must then have a listing of manufacturers and models of the relevant power supplies.

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).3 B" u& N$ y, O7 A. \+ c
