The TIDA-010244 design supports up to 3 Phases + Neutral configuration with shunt sensors and requires connections to four current inputs and three voltage inputs in this configuration.
AC voltages and currents can be applied to the board for testing purposes at these points:
- Terminal blocks J5, J6, and J7, correspond to the line voltage connections for Phases A, B, and C, respectively. These terminal blocks have two positions.
- Terminal blocks J8, J9, and J10 correspond to the current inputs
from the shunt sensors for Phases A, B, and C, respectively. These are
three-position terminal blocks but only the leftmost and rightmost positions are
used. The center position, which is connected to GND, is not connected to the
shunt sensor. During testing make sure that the applied current to the shunt
does not exceed 120A. In addition, before performing any test, verify that
this terminal block is securely connected to both output leads of the
shunt.
- Terminal block J11 corresponds to the current input from the shunt sensor for
the Neutral line. This terminal block is a three-position terminal block but
only the leftmost and rightmost positions are used. The center position, which
is connected to GND, is not connected to the shunt. During testing make sure
that the applied current to the shunt does not exceed 120A. In addition,
before performing any test, verify that this terminal block is securely
connected to both output leads of the shunt.
