? In areas that conform to Group 2 of DIN VDE 0100-710, any interruption to the examination and/or treatment of patients would place those patients at risk. Limit value monitoringThis is prevented through the use of changeover and monitoring units. These monitor the insulation resistance of the non-grounded IT system, the load current and the temperature of the transformer. If the set value is exceeded, the insulation monitor gives out a warning signal. Voltage monitoringIn addition, a special voltage relay monitors the voltage of the power supply and switches to a second power supply if it falls below the specified limit values.
