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 verication 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
exible 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.
