Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):' {9 s0 i7 x$ e+ k! G- ^. v# U6 z
“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.$ s' J9 V" u5 g8 K$ A/ t+ d
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.
: V( A5 x+ i" e: TThat cannot be a solution because many products are too small!”! ^: m' v* @& t8 `; A
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): |) B9 A4 n6 {; ^: r; P0 b! ^
Later 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.4 u4 V4 j- \( [, [8 P( |
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.
5 l( Z) C' ^: {$ R8 mDecision: This decision replaces 01/8 with the amended text in red:- \$ j' M) t3 v, l
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"
' F+ j: G& F1 ^$ ror5 O0 u$ O/ ^; T6 i9 J! B+ t u; W! R
"For applicable power supplies see user instructions". This statement shall also be in the user-instructions.6 c2 B* Z8 I' {- n4 s. O
The user instructions must then have a listing of manufacturers and models of the relevant power supplies.6 H, e3 o% G7 a- v! _
In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.7 ~$ F; I7 o& M& T
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).
