Re: External Interference from a Electromechanical Contactor

It's a Siemens 3TF41 (http://www.datasheetspdf.com/PDF/3TF41/943807/1), but the contactor is just an input, a different circuit is triggering the contactor.
It may be of no use, but things improved a little bit once again, I'll look into optocouplers to isolate the contactor coil from the ESP input, because it still randomly triggering some of the buttons (that are taken care at a software level for now).
But what should be done regarding the spikes of voltage / EMI from those motors starting/stopping all over my power grid ?
