The currents listed in the tables are measured at a rated voltage of 380 V.
When selecting, connecting, and routing power cables, follow local safety regulations
and rules.
When the external conditions change, for example, the 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 1.5–1.7 times.
The nominal battery discharge current refers to the current at a voltage of 480 V when
forty 12 V batteries are configured.
The maximum battery discharge current refers to the current when forty 12 V batteries,
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 and compatible with
application scenarios with 30–50 batteries.
When the mains input and bypass input share a power source, configure input power
cables as mains input power cables. In addition, cables listed in the table apply only to
the following conditions:
− Routing mode: The cables are routed over a ladder or bracket in a single layer (E in
IEC60364-5-52). The distance between cables should be greater than twice the
cable diameter. Routing mode: The cables are routed over a ladder or bracket in a
single layer (E multi-core and G single-core in IEC60364-5-52).
The ambient temperature is 30° C.
−
− The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
− 90° C flexible copper power cable.
− It is recommended that the AC power cable be no longer than 30 meters and the DC
power cable be no longer than 50 meters.
