NORDAC START (SK 135E / SK 175E) – Users Manual for Motor Starters68 BU 0135 en-41184.2.3 Commissioning examplesAll SK 1x5E devices can basically be operated in the condition in which they are delivered.If an automatic start-up is required when "Mains on" takes place (depending on setting P130), eitheradapt parameter (P428) or set DIP switch S1-DIP1 = ON.The PTC input must be bypassed, if a motor with PTC is not available.The motor starter must be provided with an external 24 V DC control voltage.Minimal configurationMotor starterSK 1x5E-...
