When selecting, connecting, and routing cables, follow local safety regulations
and rules.
If external conditions such as 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 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 30–50 batteries.
When the mains input and bypass input share a power source, configure
mains input power cables as input power cables. The cables listed in
3-2 and Table 3-3 are used 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.
– Ambient temperature: 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.
NO TICE
