All components which are connected to the SRD in an explosion hazardous area, require an Ex-Approval The applicable
limit values must not be exceeded in any event These limit values also have to be adhered to when connecting additional
capacitances, inductances, voltages and currents The FISCO model is thereby used as a basis
