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" e3 }$ v1 `$ x; w7 a; I, W( |

associated 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。9 [2 p! @) d, O/ S

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。 |
