The rated voltage of the SmartLi is 512 V. The voltage is 408 V at the maximum discharge
current.
The currents listed in the tables 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 change, for example, the cable layout or
ambient temperatures, perform verification in accordance with the
IEC-60364-5-52 or the 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 1.5–1.7 times.
The nominal battery discharge current refers to the current at a voltage of
480 V when forty 12 V batteries are configured.
The maximum battery discharge current refers to the current when forty 12 V
batteries, 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 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
table apply only to the following conditions:
– Routing mode: Mains and bypass input and output power cables are
routed over a ladder or bracket (E in IEC 60364-5-52), and the distance
