Safety concept for vehicle installation INFORMATION This safety concept is a recommendation of BRUSA Elektronik AG and is a general requirement for the safe operation of electric vehicles! 6.7.1 General interlock function The interlock switches (1) are closed if the respective interlock conditions of the individual devices are met (closed service cap, HV connections plugged-in...).
Interlock signal The interlock signal is to be guided through all HV-carrying connectors in a HV system. The signal of the BDC546 can be evaluated via pin 19 of the control connector. A rectangular signal frequency of 86 Hz ≤ f ≤ 90 Hz is regarded by the component as permissible.
