User Manual of EM730/EM730E Series Inverter will cause damage to the rectifier part of the inverter. In this case, please connect a three-phase AC reactor (optional) to the input side of the inverter. This will not only suppress the peak current and voltage, but also improve the power factor of the system. Installation of surge suppressor electromagnetic circuit breaker, etc.) is connected near the inverter, please install a surge When an inductive load (electromagnetic contactor, solenoid valve, solenoid coil, suppressor.
Installation of noise filter on power supply side The noise filter is used to suppress the noise that invades the inverter from the power cable, and the impact of inverter noise on the power grid. Use a dedicated noise filter for the inverter. Ordinary noise filters do not have good effects, so they are not used usually. The correct and incorrect installations of the noise filter are shown in Fig. 3-5 and Fig. 3-6.
