that the height (altitude) difference of all platforms does not exceed 5 mm.
Issue 06 (2020-08-19)
NO TE
The site ground resistance must be less than 0.1 ohm.
The cable flame spread rating must be at least VB.
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 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 distance between the cable and the cable is twice the diameter of
the cable.
● 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 soft power cables with copper conductors are used.
● It is recommended that AC power cables be no longer than 30 m.
