used, the wire thickness cannot exceed 1.5 mm², and the length cannot exceed 25m. If crimp terminals are used,
the wire can be up to 0.75 mm² for a 15 m length of wiring, or up to 1.0 mm² if 20 m is required. Longer wiring
is not supported. The ground impedance cannot exceed 5 ohms.
连接电源线和接地线。接裸线最大支持 1.5mm²（长度最大支持 25m）电源线，配压线端子支持 0.75mm²（长度最大支
持 15m）或 1.0mm²（长度最大支持 20m）电源线。接地线要求阻抗≤ 5Ω。
NOTE/ 说明
If a Huawei adapter is used, connect the power cable following the instructions on positive and negative
power terminals shown in the figure. If an optional adapter is used, connect the power cable according to
the actual positive and negative terminals of the adapter.
若使用华为原装适配器，则按图示电源正负极说明连接电源线。若使用选配的适配器，请根据适配器实际正负极连接
电源线。

cable port in sequence, thread the network cable through the kit (If the network cable cannot be threaded
through the kit, cut off the RJ45 connector.), and install the components in the sequence marked in the following
figure. The waterproof connector of the network cable must be secured tightly, or they may come loose later.
连接网线。先把网线接口上防水套件的组件 1、组件 2 和组件 3 依次旋转拆卸，然后穿入网线（如果网线水晶头带护套无法
穿入，请剥离护套。若护套不可剥离，请剪掉水晶头后再重新铆压。），再将各组件按如图所示顺序安装。网线防水接头务
必拧紧到位，否则会有脱落风险。
