3.6 Noise Control and Measures for Harmonic Suppression3-293 Wiring and Connection3.6.2 Precautions on Connecting Noise FilterThis section describes the precautions on installing a noise filter.(1) Noise Filter Brake Power SupplyIf using a servomotor with a holding brake, use the following noise filter on the brake power supply input.Model: FN2070-6/07 (Manufactured by SCHAFFNER Electronic.)(2) Precautions on Using Noise FiltersAlways observe the following installation and wiring instructions.Do not put the input and output lines in the same duct or bundle them together.Separate the noise filter ground wire from the output lines.Do not accommodate the noise filter ground wire, output lines and other signal lines in the sameduct or bundle them together.Some noise filters have large leakage currents. The grounding measures taken alsoaffects the extent of the leakage current. If necessary, select an appropriate leakage cur-rent detector or leakage current breaker taking into account the grounding measures thatare used and leakage current from the noise filter. Contact the manufacturer of the noisefilter for details.Separate these circuits.NoiseFilterIncorrect CorrectNoiseFilterNoiseFilterNoiseFilterGround plate Ground plateGround plateGround plateNoiseFilter NoiseFilterThe ground wirecan be close toinput lines.Ground plate Ground plateIncorrect Correct
