Page 14 The AC DRIVE will generate high harmonic electromagnetic noise, so using the following noise measures is recommended. Insert a noise filter on the input side of the AC DRIVE. Contact Amtech to select the proper noise filter. Keep the wiring length between the noise filter and AC DRIVE to 500mm (19.7”) or less.
Page 15 AC DRIVE is running. Directly connect only motor to the AC DRIVE load and do not connect through a transformer etc...without consulting Amtech. (Note 7) Grounding Always ground the AC DRIVE unit according to the regulations of the country where the AC DRIVE is being used to ensure personnel safety in all circumstances, and to reduce electromagnetic emission and pickup.
