When the external conditions such as the cable layout or ambient temperatures change,
perform verification in accordance with the IEC-60364-5-52 or 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 to 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 30–50 batteries.
When the mains input and bypass input share a power source, configure mains input
power cables as input power cables. In addition, cables recommended in the table apply
only when the following requirements are met:
−
Routing mode: The cables are routed over a tray or bracket in a single layer (E in
IEC 60364-5-52). The distance between cables should be greater than twice the
cable diameter. Routing mode: The cables are routed over a tray or bracket in a
single layer (E multi-core and G single-core in IEC 60364-5-52).
−
The ambient temperature is 30°C.
−
The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
−
The 90°C flexible cables with copper conductors are used.
−
It is recommended that AC power cables be no longer than 30 meters and DC power
cables be no longer than 50 meters.
When connecting power cables, comply with the tightening torque listed in Table 3-3 to
ensure secure connections and prevent safety risks.
