请教大神以下UL60730-1这段怎么理解
11.6.3.5 INDEPENDENTLY MOUNTED CONTROLS for surface mounting or the sub-bases for such CONTROLS shall be constructed in such a manner that the terminals for EXTERNAL CONDUCTORS are accessible and can be used when the CONTROL or the sub-base is correctly fixed to its support and its COVER (or the CONTROL) is removed.

个人理解:

可用于独立安装的控制器 (INDEPENDENTLY MOUNTED CONTROLS ), 当正常安装后, 只要打开盖子后, 端子可以触及并供使用。

相反地, 如果端子连接必须在安装在固定位置前先连接好, 而安装在固定位置后便不能连接或断开, 则不能符合 INDEPENDENTLY MOUNTED CONTROLS。
