When selecting, connecting, and routing power cables, follow local safety regulations
and rules.
The cable selection is based on the maximum current under extreme conditions (e.g. low
voltage, overload).
When the external conditions change, for example, cable layout or ambient temperatures,
perform verification in accordance with the IEC-60364-5-52 or the local regulations.
If the rated voltage is 400 V, multiply the currents by 0.95; if the rated voltage is 415 V,
multiply the currents by 0.92.
When the primary loads are non-linear loads, increase the cross-sectional areas of the
neutral wires by 1.5–1.7 times.
The nominal battery discharge current refers to the current of forty 12 V batteries at 480
V in standard configuration.
The maximum battery discharge current refers to the current when forty 12 V batteries in
standard configuration, that is, two hundred and forty 2 V battery cells (1.67 V/cell), stop
discharging.
The battery cable specifications are selected based on 40 batteries by default and
compatible with application scenarios with 30–44 batteries.
