11.1.1 Connection diagram of the voltage inputs
RPV311-TM-EN-7
Before making the electrical connection, make sure the signal is applied in
accordance with the technical specifications of the equipment. For information about
analog voltage inputs specifications, see Chapter 17: Technical Specifications.
The RPV311 provides the capability for making some different voltage signal
connections for a 3-phase circuit:
Connection diagram of the voltage inputs
4-element connection: in this
case, the values shown are
equivalent to the voltages of
phases A, B and C, and to the
neutral voltage applied to the
equipment.
3-element (Phases A, B and C)
connection: in this case, the
fourth element is derived of the
values measured by the other
elements. The three elements
are equivalent to the values
applied to the equipment
3-element (Phases A, B and
neutral) connection: in this
case, the fourth element is
synthesized of the
measured by the
elements. The three elements
are equivalent to the values
applied to the equipment.
