For all such devicesconnected to or near the soft starter or its wiring, see Fig. 11 and observe the following.24 V DC Coils. Connect a diode directly across each DC coil. A standard diode (e.g. 1N4004) is acceptable for most24 V DC applications up to 1.0 A.CAUTIONThe control outputs are semiconductor (solid-state) outputs. Applyingimproper control voltage and/or frequency can damage the control circuits.Use control circuits only at the rated voltage and frequency. 24 V DC modelshave solid-state FET outputs and should not be used on AC circuits.Alternately, 115 V AC & 230 V AC models have triac outputs and should not beused on DC circuits.DC CoilAC Coil+24 VDCSwitch+Switch120/230 VAC220 Ohm1/4 Watt0,47 µF,600 V DC/230 V ACFig. 11 : Inductive Load Suppression12 3ZX1012-0RW34-1AN1
