charger, and the cable shall be laid through the cable trench.
2. The AC cable adopts copper core wire, and the cross-sectional area of the cable shall
adapt to the load.
3. The outdoor power cable shall be laid according to the power specification. The
power cable and the signal cable must be separated, and the signal cable should be put
through the tube separately to avoid the pressure loss and interference of the
communication signal.
4. The cable shall not be laid in the area easily damaged by mechanical damage,
corrosive medium emission, humidity, strong magnetic field and strong electrostatic field
interference. If necessary, please take corresponding protection or shielding measures.
5. The AC input cable starts from the user's distribution switch and connects to the
copper bar of the charger's inlet cable switch. Protection devices shall be provided at the
user's power distribution.
6. The color of AC input cable is brown (L1), black (L2), gray (L3), blue (N), yellow green
(PE). If the input cable has only one color, it is necessary to paste cable number identification
(or tube with mark).

SEC 240kW Series DC Fast Charger--- User Manual
12
3.3.2 Process requirements of distribution cables
1. Cable laying shall be free from external force, distortion and damage of insulation
layer.
2. It is strictly forbidden to twist, flatten, break the protective layer and wear the
protective layer seriously.
3. The protective pipe shall be cleaned before the cable passes through the pipe, and
the wire shall not be damaged.
4. The cable arrangement shall be tidy. The binding should be neat and should not be
crossed.
5. Sufficient allowance shall be reserved for each wire of the cable, and the bending
degree shall be consistent.
6. Crimp the terminal of the cable head, and there should be no gap on the penetration
surface of the terminal after crimping.
7. When pressing the lug of inlet cable, the heat shrinkable tube should be set between
the cable and the lug, and the inside and outside of the tube should be smooth without
damage and crack. Before setting the heat shrinkable tube, the sundries on the cable shall be
removed, and there shall be no burr and iron filings on the surface to prevent damage to the
tube. The color of the tube shall be in accordance with the phase sequence. When the tube is
heat shrinkable, the flame should be avoided to spray on the inside of the cabinet to prevent
burning the internal components and cables of the cabinet. The appearance of heat
shrinkable casing should be flat, smooth, uniform shrinkage, no dust and crack.
8. Attention should be paid to the wiring sequence when pressing RJ45 connector for
Ethernet cable. Check whether the pressing is qualified after pressing.
