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 456 V when
thirty-eight 12 V batteries are configured.
The maximum battery discharge current refers to the current when thirty-eight 12 V
batteries, that is, two hundred and twenty-eight 2 V battery cells (1.75 V/cell), stop
discharging.
The battery cable specifications are selected based on 38 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 following conditions:
− 90° C flexible copper power cable. Multi-core cables are recommended for mains
and bypass input and output power cables, and single-core cables are recommended
for battery cables.
Routing mode: Mains and bypass input and output power cables are routed over a
−
ladder or bracket (E in IEC60364-5-52), and battery cables are routed over a ladder
or bracket in a single layer (F 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%.
− It is recommended that the AC power cable be no longer than 30 meters and the DC
power cable be no longer than 40 meters.
