2 L4 P, ^! S4 z8 W( O+ XElectrical connection with the mains in such a way that a connection to either pole of the mains causes in that connection a permanent current equal to or greater than 9A, protective devices in the apparatus being not short-circuited/与电网电源的电气连接,当设备中的保护装置不短路时,与电网电源的任一极连接时会在此连接处产生大于或等于9A的稳定电流。
