(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)) j: S }# x9 p' j9 R5 M i: q3 A3 u

5 B3 F7 `& ]3 n0 U$ R( u0 Rassociated 可以是incorporated （装在器具内部，需要依赖器具外壳来防触电）和specific use(可以在器具内部或者是在器具外部，可以依赖自身的外壳来防触电）。

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。6 B% u0 u& W7 R, O# [( X( R8 H
