User Manual of A90 Series Inverter MCCB Inverter IM Transmission Radio device Signal lines interference Control device Fig. 3-7 Noise Filter Installation on Output Side 3.2.5.7 Solution to inductive interference To suppress the inductive interference on the output side, all output cables can be laid in the grounded metal tubes, in addition to the aforesaid installation of the noise filter. When the distance between the output cable and signal line is greater than 30 cm, the impact of inductive interference will decrease significantly, as shown in Fig. 3-8. MCCB Metal tube Inverter IM Signal lines > 30cm Control device Fig.
3-8 Solution to Inductive Interference 3.2.5.8 Solution to RF interference be reduced by installing noise filters on the input and output sides and shielding the inverter The input cable, output cable and inverter itself generates RF interference, which can body with an iron box, as shown in Fig. 3-9. 34 Noise filter
