关于第二点,2.1.1.5章节里面并没有说不能碰到,看以下标准:, w; x% L4 u( Q7 N3 B0 }
a) A risk of injury due to an energy hazard exists if it is likely that two or more bare parts (one: a0 p* p/ O3 V* M, T
of which may be earthed) between which a HAZARDOUS ENERGY LEVEL exists, will be bridged

b) The likelihood of bridging the parts under consideration is determined by means of the test9 K% Y# }! R; [! k* U, X
finger, Figure 2A (see 2.1.1.1), in a straight position. It shall not be possible to bridge the
