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 monitoring
This 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 monitoring
In 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.
