    Wiring Terminal and block diagram In an ET 200SP station, the AI Energy Meter 480VAC ST forms its own potential group together with its dark BaseUnit. General safety instructions WARNING Danger to life due to electric shock Touching live parts can lead to death or severe injuries. Before beginning any work deenergize the system and the Energy Meter and short-circuit installed transformers.
  • Page 16 Wiring 3.1 Terminal and block diagram Protecting the connection cables To protect the connection cables at U and U , make sure there is adequate cable protection, especially after cross-section transitions. If short-circuit resistance according to IEC 61439-1:2009 is ensured by the design, there is no need for separate cable protection for the AI Energy Meter 480VAC ST.
  • Page 17 Wiring 3.1 Terminal and block diagram Usable BaseUnit The ET 200SP Distributed I/O System manual explains that a potential group always starts with a light BaseUnit. The AI Energy Meter 480VAC ST makes an exception in this case and only uses the dark BaseUnits type D0, 6ES7193-6BP00-0BD0. The BaseUnit is not in contact with the power bus and passes the potential through from the left to the right slot.

  • Page 91 Interrupts/diagnostic alarms 13.4 Diagnostics response Loss of the supply voltage At a loss of supply voltage at U (phase 1), all measurements are interrupted. After the supply voltage is restored, the AI Energy Meter 480VAC ST operates again with the configuration / parameter assignment stored in the CPU.

You can find this application example on the 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.
