3. installation regulations For the connection of the intrinsically safe field units to the intrinsically safe circuits of the switching amplifiers the relevant maximum values of the field unit and the switching amplifier according to the explosion protection must be observed proof of intrinsic safety When the intrinsically safe circuits are used in hazardous dust areas D only certified field units are allowed to be connected The EC certificates of conformity and EC type test certificates must be adhered to Compliance with the Special Conditions which may be included therein is especially important 4 Maintenance repair The transmission characteristics of the units are stable over long periods regular adjustment or such like is therefore not necessary No maintenance is required 5 Rectification of faults Units that are operated in combination with hazardous areas must not be modified Uday Only specially qualified and authorised personnel are allowed to repair the unit Insulation coordination for units with Ex certificate in accordance with EN 60079 11 The units are rated for use in soiling degree 2 in accordance with DIN EN 50178 1 LEDs yellow Indication of the switching status output 1 output 2 lights when the corresponding output is switched the relay is energised 2 LEDs red Fault indication for input circuit 1 input circuit 2 lights in case of wire break or short circuit in the respective input circuit Th
