The rated voltage of the SmartLi is 512 V. The voltage is 408 V at the maximum discharge
current.
The currents listed in the table 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 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.
