The phase conductors of the cable are coupled to connectorsL1, L2 and L3. The earth protection coloured green-yellow is coupled to connectorIf you are using 5-lead cable, you must connect neutral conductor withterminal N.*) In cables of S type there is a protective grounding conductor coloured green-yellow.2.2.2. Welding and earth cablesRecommended copper cables with cross-sectional area are as follows:Kemppi Pro Evolution 3200 50 ... 70 mm2Kemppi Pro Evolution 4200 70 ... 90 mm2Kemppi Pro Evolution 5200 70 ... 90 mm2In enclosed table are shown typical load capacities of rubber insulated copper cables, whenambient temperature is 25 ºC and lead temperature is 85 ºC.CABLE DUTY CYCLE ED VOLTAGE LOSS / 10m...........................100% .........60% ........... 30%50 mm 2 ..............285 A .........370 A ......... 520 A ...........0,35 V / 100 A70 mm 2 ..............355 A .........460 A ......... 650 A ...........0,25 V / 100 A95 mm 2 ..............430 A .........560 A ......... 790 A ...........0,18 V / 100 ADo not overload welding cables due to voltage losses and heating.Fasten the earth clamp of the return current cable carefully, preferably direct onto the piece to bewelded.
