Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
0 q% b9 b3 L M1 b) y# c9 q“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.
- m2 D1 V) G0 _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.5 ~0 g6 c3 I4 _# v% b1 K! ~+ B3 U; e* i
That cannot be a solution because many products are too small!”* Z& K. K$ Z3 B: Z% Q
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):
( s2 J- \# a( J! tLater 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.
& L# Q% R; ]! k# Y; W Y# Q3 }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 1.7.2.1 o. o; z z9 S9 ]4 o2 C/ a$ I7 G3 C
Decision: This decision replaces 01/8 with the amended text in red:- u! v, l3 \( m: 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"0 n0 j# \& a( R! q g* u
or' O8 ]: H# t5 j6 [; M l2 A
"For applicable power supplies see user instructions". This statement shall also be in the user-instructions.: o8 m! u' h# y c- j: {1 E: B
The user instructions must then have a listing of manufacturers and models of the relevant power supplies.6 s/ z9 p6 I( k: a7 c6 h
In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.
/ n9 m# \# n. Z$ MAs 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).
