The following situations are exempt from the above requirements:
# T& N: ^. ?) V% b+ n – 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) ; % s, W7 X; u+ }5 {: d3 G
本人理解如下:
5 x# D5 ]; L6 u8 ~, w' L4 e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。
! [6 |& T/ S: c6 v7 X3 B – 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.;$ ` f- J8 ], b' I4 m8 o' J
-->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。
