ENThe cable is entered into the machine through the inlet ring on the rear wall of the machineand locked with a cable clamp (05).The phase conductors of the cable are coupled to connectors L1, L2 and L3. The earthprotection coloured green-yellow is coupled to connector marked with earth protectionsymbol . If you are using 5-conductor cable, you must cut the zero conductor to the level ofthe cable´s protective shield.sizes of mains cables and fuse ratings for the machine at 100% ed duty cycle arespecified in the table below:Kempoweld 3200, 3200WConnected voltage 230 V 400 VVoltage range 220 – 240 V 380 – 415 VFuses, delayed 20 A 16 AConnected cable 4 x 2.5 S mm² 4 x 2.5 S mm²In cables of S type there is protective grounding conductor coloured green-yellow.NOTE! This equipment’s electromagnetic compatibility (EMC) is designed for use in an industrialenvironment. Class A equipment is not intended for use in residential location where the electricalpower is provided by the public low-voltage supply system.Change of mains voltageConnection 3~ 230 or 3~ 400 V of mains voltageBy delivery from the factory the machine has been connected for mains voltage 3~ 400 V.In order to change the mains voltage, remove the side plate of the machine. Change theconnections according to the enclosed diagram. You find the corresponding wiring diagramon the instruction label, which is under terminal block.2.4 Welding and return Current CablesUse only copper cables with cross-sectional area of at least 50 mm². In enclosed tableare shown typical loading capacities of rubber insulated copper cables, when ambienttemperature is 25 °C and conductor temperature is 85 °C.cable cross-section duty cycle ED voltage loss / 10 mCu 100 % 60 % 40 % for 100 A50 mm² 285 A 370 A 450 A 0.35 VFasten the earthing press of the return current cable carefully, preferably direct onto the pieceto be welded. The contact surface area of the press should always be as large and steady aspossible.Do not overload welding cables over permissible values due to voltage losses and heating.Clean the contact surface from paint and rust.8Kempoweld 3200, 3200W / © Kemppi Oy / 1117
