SMVRCV can also be connected to both ULTVTR1 and RESTVTR1. This means that both the three phase voltages U1, U2, U3 and the residual voltage Uo are replaced by the received IEC 61850-9-2 LE sample value.

Note: All three signals UL1, UL2 and UL3 must always be connected between SMVRCV and ULTVTR1.
Note: The IEC 61850-9-2 LE stream always contains UL1, UL2, UL3 and Uo. When the three phase voltage channels are received from IEC 61850-9-2 LE, the setting VT connection in Configuration > Analog inputs > Voltage (3U,VT) must be “Wye”.
