对于 assciated 和 independent的理解，可以参看IEC 61558-1中对类似类型变压器的解释3.1.6, 3.1.6.1, 3.1.6.2以及3.1.7
3 J2 {3 j4 _2 \! J(61347-2-13在定义上极大程度地借鉴了IEC 61558-1, 当然一个是针对变压器，一个是针对控制装置)

由此看来，装不装在器具内部，有没有自身的外壳，不是区分associated和independent的重点。
' r" P2 ?- ]* x, c5 Q! S; v) f" e8 r* s) }. |/ b& {
区分的重点在于associated是给特定的设备供电的（例如61347－2－13拿应急照明装置的情况来举了一个例子）;而indepedent是可以给不特定的设备供电的。

61347－2－13中提及的independent，特指可以给不特定照明设备供电的控制装置。 |
