The rated voltage of the SmartLi is 512 V. The voltage is 408 V at the maximum discharge
current.
When selecting, connecting, and routing power 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.
If primary loads are non-linear loads, increase the cross-sectional areas of
neutral wires 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 30–44 batteries.
When the mains input and bypass input share a power source, configure both
types of input power cables as mains input power cables. The cables listed in
Table 3-2 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.
– 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.
– The length of the AC power cables of a UPS is no longer than 30 m and
DC power cables no longer than 50 m.
