    Meter . Measuring and visualizing energy data You can find these application example at Internet (http://support.automation.siemens.com/WW/view/en/86299299) IT network You must create an artificial N-conductor (for example, by means of a 1:1 voltage transformer) in IT networks due to the missing neutral conductor. You can then use the module.
