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.
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 by 1.5–1.7 times.
The recommended cables 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 or F in
IEC 60364-5-523).
● Ambient temperature: 30°C
● The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
● Single- or multi-core 90°C-resistant copper flexible cables are used.
● It is recommended that AC power cables be no longer than 30 m and DC power cables
be no longer than 40 m.
