4. EUROPOWER MANUAL IB PROTECTOR Pag 1 5 Functional description of the safety relay IB Protector 0 Introduction The safety relay IB Protector protects users and appliances against electric failures in a non earthed mains U mains through insulation resistance protection It makes the use of an earth leakage protection redundant This makes it very useful in combination with mobile gensets because the generator phase earthing or neutral point earthing does not have to be earthed by means of an earth pin in the ground In case a failure occurs the safety relay IB Protector will disconnect the generator voltage through an external power relay The insulation resistance between the ground conductor PE and the live conductors is measured continuously The detection threshold can be preset between 30kOhm and 120kOhm Moreover several extra functions can be installed over or undervoltage frequency that is too high or too low These functions can be activated or deactivated by the manufacturer by means of an internal DIP switch The safety relay IB Protector is equipped with 2 switches An insulation failure can be simulated by means of a test switch The safety relay can be activated again through the reset switch The activation of the power relay can be protected against undesired use by means of a secret code At each start a self test is done First the power relay is checked e g failure caused by sticking or bridging
