The prevention from electrical noise could be different depending on the type of noise. The followings are some examples per electrical noise type. EMI (Electro Magnetic Interference) • Enclose the product in the metal box • Connect a FG (frame ground) • Use shielded cable • Use Ferrite core (Ferrite bead) EMS (Electro Magnetic Susceptibility) • Noise filter • Serge suppressor for relays, solenoids, or switches • Connect FG (Frame Ground). Make sure connect only one point of each component; driver, controller, motor.. Noise source example; Relay, solenoid, motor wires, any high voltage component • Separate the signal lines from the noise source • Twisted pair wires (twist tight, the more twist is the better result) • Use serge suppressor or varister for the relays or switches.
