MC200H BENDING MACHINE INSTRUCTION BOOK 10IMPORTANTThis machine must be connected to an electrical outlet with earthing contact.4.4 Instructions for connecting to the power supplyThe MC200H bending machine comes equipped with a 230V/ 400V 1.1Kw three-phase motor for the oper-ation of the rollers and a 230V/ 400V 0.75 Kw three-phase motor to regulate the hydraulic piston, bothready to be connected to a 400V power supply. The machine must be connected with the plug installed to acompatible power supply that meets the requirements specified.If you want to connect the machine to a 230V three-phase voltage, a series of changes must be made tothe electrical panel. These are the following:- Change of the main motor coil connections- Change of the hydraulic motor coil connections- Change of the transformer connections- Adjustment of the intensity range of the motor guard contactors.Change of the motor connection:When the power supply voltage is 400V three-phase, we perform the connection in a Star shape (defaultsetting in the machine). In the case of 230V three-phase, we perform the connection in a Triangle shape.As shown in the figure.The modification of the connection must be made through the motor terminal box located in the rear of themachine, changing the configuration of the flats according to the power voltage.Figure 7. Change of engine connectionsA check must be carried out to ensure that the machine is not connected to the power supply pri-or to making any modification to the connection or the electrical panel.Star figure(Default)For voltage 400VTriangle figureFor voltage 230V |
