Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
5 Z3 o( J, l- G, Y! v“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.
- M/ |+ S, ` d8 t9 p+ QWe 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., k I, T! O' w" M4 y
That cannot be a solution because many products are too small!”6 f A$ w; m5 F. W, I! p$ n
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):
; D( w, A" e# Z. n6 x9 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.$ a) m# ~1 J) n1 ]% N2 [+ z& G
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.
# }6 I8 p+ j+ R7 y$ O8 E3 M7 SDecision: This decision replaces 01/8 with the amended text in red:
/ O5 L; X! l' B% i9 a. A4 yA 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"
. W d$ _! A5 k# `or: b% F+ o+ j4 \+ W1 P( O' [( V3 r: S
"For applicable power supplies see user instructions". This statement shall also be in the user-instructions.$ E/ _3 M+ e9 O* o, l
The user instructions must then have a listing of manufacturers and models of the relevant power supplies.
1 o B0 n, o; u) ?: }In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.6 j. b' E! R/ |% K" a; Q" G8 g
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).) E1 v! Q$ D/ {/ W' g
