  • Page 85 CHAPTER 8 - OPTIONS AND ACCESSORIES Always add a line reactor, when capacitors for power factor correction are installed in the same line and near to the inverter. Figure 8.2 shows the line reactor connection to the input. Use the following equation to calculate the value of the line reactor necessary to obtain the desired percentage of the voltage drop: L = 1592 .

    (as a function of the "transmission line" effect) are used. WEG Motor with voltages up to 460V, no use of load reactor is required, since the insulation of the motor wires support the operation bi the CFW-10. If the cables between inverter and motor are longer than 100m (300ft), the cable capacitance to ground increases.

    CHAPTER 8 - OPTIONS AND ACCESSORIES In any case, the RMS current capacity and the maximum peak current shall be respected. The maximum peak current defines the minimum resistance value (ohms) of the braking resistor. Refer to table 8.3. The DC Link voltage level at which the rheostatic braking is activated is the following: - CFW-10 200-240V models –...
