(2)Use shielded cables for the power and control cables, including filter input cables and inverter output ca- bles. Route the cables and wires so as to minimize their lengths. Keep a distance between the power ca- ble and the control cable and between the input and output wires of the power cable. Do not route them in parallel or bind them together, instead cross at right angle.

(3)Install the inverter and the filter on the same metal plate. It is more effective in limiting the radiation noise to install the inverter in a sealed steel cabinet. Using wires as thick and short as possible, earth the metal plate and the control panel securely with a distance kept between the earth cable and the power cable.

(4)Route the EMI filter input and output wires apart from each other.

(5)To limit the radiation noise from cables, earth each shielded cable to the metal plate. It is effective to earth shielded cables in the vicinity of the inverter, cabinet and filter (within a radius of 10cm from each of them). Inserting a ferrite core in a shielded cable is even more effective in limiting the radiation noise.

(6)To further limit the radiation noise, insert a zero-phase reactor in the inverter output line and insert ferrite cores in the earth cables of the metal plate and cabinet.
