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.
When the external conditions such as cable layout or ambient temperatures change, perform verification
in accordance with the IEC-60364-5-52 or the local regulations.
The currents listed in the table "Recommended cross-sectional areas for power cables" are measured at a
rated voltage of 380 V; 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 recommended cables are applicable only when the following requirements are met:
 The cables are routed over a ladder or bracket in a single layer (E or F in IEC60364-5-523).

The ambient temperature is 30° C.
