Correct grounding of the inverter is an important means to improve the sensitivity of the control system and suppress the noise. The grounding resistance of the grounding terminal E(G) of the inverter is as small as possible. The cross-sectional area of ​​the grounding conductor should be no less than 2mm and the length should be controlled within 20m. The grounding of the inverter must be separated from the grounding point of the power equipment and cannot be grounded. The shield of the signal input line should be connected to E(G), and the other end must not be connected to the ground. Otherwise, the signal will fluctuate and the system will not oscillate. The inverter and the control cabinet should be electrically connected. If the installation is difficult, the copper core wire can be used for bridging.
