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 400VAC 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.
When using some older CPUs / interface modules, note that the first permissible place for
AI Energy Meter 400VAC ST is slot 2.
Connection types
The AI Energy Meter 400VAC ST supports the following connection types:
● 3P4W, 3 phases, 4 conductors
● 1P2W, 1 phase, 2 conductors
The input circuit of the module must correspond to one of the listed connection types. Select
the appropriate connection type for the intended use.
You will find examples of connections in the section Connection examples (Page 19).
Information on the selection of a current transformer is available in the section Current
transformer selection data (Page 20).
