华为ETP48100按装DCDU/ETP48100电源输入线 

a) 直流：裁剪16mm2蓝黑电源线并压接端子，连接至DCDU与电源柜 

b) 交流：将交流输入电源线两端分别连接至ETP48100与AC220V电源插排，多余线缆盘绕绑扎在机框旁边 

线缆布放时须用绝缘胶带缠绕端头，使之绝缘，电源柜侧接电时，须使用经过绝缘处理的工具，接电前需确认空开关闭或拔出熔丝  

电源线和信号线需间隔30mm固定，室内用白色线扣十字交叉绑扎，齐根剪平不拉尖，室外用黑色线扣，留3-5mm后剪掉.

HUAWEI ETP48100 press on DCDU/ETP48100 power input line

A) DC: trimming 16mm2 blue black power cord and crimping terminal, connecting to DCDU and power cabinet.

B) AC: Connect the two ends of the AC input power cord to the ETP48100 and the AC220V power strip respectively, and the redundant cables are coiled and tied beside the frame.

Insulation tape should be used to wrap the ends of the cables when placing them. Insulation tools should be used when the side of the power cabinet is connected with electricity.

The power and signal wires should be fixed at intervals of 30 mm. The power and signal wires should be crossed and tied with white thread buckles indoors. The power wires should be cut flat without pulling the tips. The black thread buckles should be used outdoors. Leave them 3-5mm and then cut them off.
