For the detailed power distribution requirements, refer to the solution in use.
The external ground resistance of the container must not exceed 10 ohms, or the
equivalent radius of the ground grid is no less than 5 m.
The upper end of the pre-installed ground grid must be at least 0.7 m underground. In
cold areas, the ground electrodes must be buried under the frozen layer.
At least two ground points on each container must be properly grounded.
Do not connect devices such as fuses and switches to ground cables.
Ground cables should be short, straight, and not coiled.
