Data” If the device does not function after commissioning, itmust be returned to the manufacturer unopened. Open-ing the device will void the warranty The auxiliary contact 41-42 may not be used as a safetycontact Use adequate protective circuit for inductive loads (e.g.free-wheeling diode)Installation As per EN 60204-1, the device is intended for installationin control cabinets with a minimum degree of protection ofIP54. The following should be noted: Mounting on 35 mm rail according to EN 60715 Ensure sufficient heat dissipation in the control cabinet Minimum distance to adjacent devices according to thetotal current limit curveSafetyPrecautionsFig. 1 Block diagram SR3EFig. 3 Mounting / DemountingFig. 4 TerminalsA1: Power supplyA2 : Power supplyS11: Control voltageS10: Control lineS21: Start control lineS13: Control lineS14: Control lineS12: Control line13-14: Safety contact 123-24: Safety contact 233-34: Safety contact 341-42: Auxiliary contactto the device. It is not allowed to open the device, tamper with thedevice or bypass the safety devices. All relevant safety regulations and standards are to beobserved. The overall concept of the control system in which thedevice is incorporated must be validated by the user. Failure to observe the safety regulations can result indeath, serious injury and serious damage. Note down the version of the product (see label “Ver.”)and check it prior to every commissioning of a new de-vice. If the version has changed, the overall concept ofthe control system in which the device is incorporatedmust be validated again by the user. Installation and commissioning of the device must beperformed only by authorized personnel and who hasread and understood this operating instructions. Observe the country-specific regulations when installingthe device. The electrical connection of the device is only allowed tobe made with the device isolated. The wiring of the device must comply with the instruc-tions in this operating instructions, otherwise there is arisk that the safety function will be lost. It is not allowed to open the device, tamper with thedevice or bypass the safety devices. The contact protection and the insulation of the supplycables must be designed for the highest voltageFig. 2 State diagram for SR3E with manual start
