The following situations are exempt from the above requirements:
: X, |5 c' ^4 K7 C! v – where terminals for the connection of a supply are provided on a component (for example, a terminal block) or subassembly (for example, a power supply unit), the symbol(没圈的接地符号) is permitted for the protective earthing terminal instead of(有圈的接地符号) ;
: C5 j6 X2 N6 d+ _* T! b- h6 e) |本人理解如下:
8 R) k( H( c2 A如果设备的端子连接的是一个零件(例如一个终端模块)或者组件(比如一个电源),有圈的接地符号可以代替没圈的接地符号。
; p9 I o, ]# Q – on subassemblies or components, the symbol(有圈的接地符号) is permitted in place of the symbol(没圈的接地符号)provided that it does not give rise to confusion.;1 j& E, i9 \ C5 U
-->组件或者零件间的连接,如果用没圈的接地符号代替没圈的接地符号不会引起误解,则允许替代。
