EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Noise Filter Installation on the Output Side (As Shown in Figure 3–8). MCCB IM Conducted Interference Radio Device Signal Line Control Device Figure 3–8 Noise Filter Installation on the Output Side 3.2.6.7 Countermeasures Against Inductive Interference In addition to the installation of a noise filter, the method of the all output cables into the grounded metal pipe can be adopted to suppress the inductive interference on the output side. The distance between the output cable and the signal line shall be greater than 30cm and the inductive interference decreases substantially, as shown in Figure 3–9.
