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 480 V.
When selecting, connecting, and routing cables, follow local safety regulations
and rules.
When the external conditions such as cable routing or ambient temperature
change, perform verification in accordance with the IEC 60364-5-52 or local
regulations.
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).
– Ambient temperature: 30°C
