3. Connect one end of the earth cable to the user earth bar, and the other end to the earth bar in the AC distribution cabinet (See Figure 31 and Figure 32 ).
4. Lead out the DC earth cable from the positive busbar of the DC distribution cabinet, and connect it to the copper earth bar in the equipment room. The sectional area of the DC earth cable increases with system capacity, and should be at least 95mm 2 .
Connecting Cables Between Rectifier Cabinet and AC Distribution Cabinet
For Rack1000-A rectifier cabinet, choose one 160A MCB as AC input switch of the rectifier cabinet.
For Rack1500-A and Rack2000-A rectifier cabinets, choose two 160A MCBs as AC input switches of the rectifier cabinet.
Follow the steps below to install the AC input cables of the rectifier cabinet.
1. If the AC input cables of the rectifier cabinet are routed inside the cabinets, users can use the accessory cables as the AC input cables. Otherwise users need to prepare armored cables by themselves. If the system capacity exceeds 2000A, users need to prepare extra cables. The cable specification cannot greater than 50mm 2 . The wiring is shown in Figure 33 .
