Do not overload power strips and extension cords.Overloading can result in fire or electric shock. 不要使电源插座和外接电源线过载，否则可能导致电击或火灾。
The latter can be used to prevent the surge current or overload currents from the security zone transmission to the dangerous place to ensure the reliable isolation security. 后者采用能防止浪涌电流或过载电流从安全区传输到危险场所的高度可靠的隔离措施来保证安全。
