When selecting, connecting, and routing 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.
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.
Signal cables must be double-insulated twisted cables. If the cable length is within 25–50
m, the cross-sectional area must be 0.5–1.5 mm
The recommended cables are applicable 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).
● The ambient temperature is 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.
