Chapter 15 – Installation
Before making the electrical connection, make sure the signal is applied in accordance with the technical
specifications of the equipment. For information about analog current inputs specifications, see Section 2.4
of the Specifications Chapter 17.
5.9.1 CONNECTION DIAGRAM OF THE CURRENT INPUTS
The RPV311 provides the capability for connecting some different current signal connections for a 3-phase
circuit:
Connection diagram of the current 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
derived of the values measured by the other
elements. The three elements are equivalent to
the values applied to the equipment.
