请教标准中,如下条款 ,感觉很抽象,不知道怎么理解
Circuits with TERMINALS which are HAZARDOUS LIVE

These circuits shall not be connected to ACCESSIBLE conductive parts, except for circuits
which are not MAINS CIRCUITS, and which are designed to be operated with one TERMINAL
contact at earth potential. In such cases, the ACCESSIBLEconductive parts shall not be
HAZARDOUS LIVE.
If such a circuit is also designed to be operated with one ACCESSIBLE TERMINAL contact (signal
low) floating at a voltage which is not HAZARDOUS LIVE, this TERMINALcontact is permitted to be
connected to a common FUNCTIONAL EARTH TERMINAL or system (for example, a coaxial
screening system). This common FUNCTIONAL EARTH TERMINALor system is also permitted to
be connected to other ACCESSIBLE conductive parts.

我的理解:
带有危险带电端子的电路
这些电路不可以连接到可接触导体部分, 但是~~~~除外

If such a circuit is also designed to be operated with one ACCESSIBLE TERMINAL contact (signal
low) floating at a voltage which is not HAZARDOUS LIVE
第一段中要求接地了, 这里说的非危害悬浮电压怎么理解?

this TERMINALcontact is permitted to be
connected to a common FUNCTIONAL EARTH TERMINAL or system (for example, a coaxial
screening system). This common FUNCTIONAL EARTH TERMINALor system is also permitted to
be connected to other ACCESSIBLE conductive parts.
第一段已经允许接到地系统了,这里有牵扯出公共功能地系统??太抽象了,到底在说什么???

如果我的设备,有一个输出端子,是接客户的设备,电压不能确保一定无危害,该怎么处理???
