Connections to Sensors and to the 71M654x
Figure 3 shows the sensor connections for single-phase meter application using a 71M6541D/F and
71M6x01. This single-phase configuration uses one local shunt and one shunt isolated with a 71M6x01
device. Since the local shunt is connected to the LINE circuit, the meter is also referenced to the LINE
circuit.
Figure 4 shows the sensor connections for a polyphase meter application using a 71M6543F/H or
71M6545/H. This polyphase configuration uses three 71M6xx3 to isolate the shunt sensors for the three
phases, while a locally connected fourth shunt sensor can be optionally used to sense neutral current.
Since the local shunt is connected to the neutral circuit, the meter is also referenced to the neutral circuit.
