Connecting AC Input Cables
Connection requirements
1. The AC input cables are wired from the user distribution switch, and connected to the output terminal when the power is to be
switched on. The AC input is fitted with protection devices for over-current, short circuit and lightning protection devices. The
capacity of the distribution switch should not be less than 1.5 ~ 2 times of the load capacity.
2. The yellow, green, red, and light blue AC cables correspond respectively to the AC phase A, B, C and neutral lines. If the cables
are of the same color, they should be numbered or identified with insulating tape of different colors at both cable ends.
3. The AC cables should be wired separately from the DC cables, with separation exceeding 150mm.
4. No splice, damage or scratch on the cables is permitted.
Connection with optional AC distribution cabinet
1. Connect the AC distribution cabinet and the user’s distribution switch outside the power system.
The AC cables can enter the system from either the top of AC distribution cabinet through cabling rack or the bottom of AC
distribution cabinet through trenching. After the AC input cables are led into the cabinet, connect them to the MCBs, as shown in
Figure 1.11.
