Data Sheet 71M6545/H
For a poly-phase configuration with neutral current sensing using shunt resistor current sensors and the
71M6xx3 isolated sensors, as shown in
differential input, to be connected to a local shunt (see
local shunt connected to the IADC0-IADC1 input is used to sense the Neutral current. The voltage
sensors (VADC8, VADC9 and VADC10) are also directly connected to the 71M6545/H (see

Using settings for the I/O RAM Mnemonics listed in
those required by the corresponding CE code being used may result in undesirable side
effects and must not be selected by the MPU. Consult your local TERIDIAN representative to
obtain the correct CE code and AFE / MUX settings corresponding to the application.
