Firmware version 7.0 allows the N60 to support a maximum of four Logical Device PMUs (Logical Device 2 through 5) and
four aggregators (located in Logical Device 1 (LD1)), while other UR family members support one PMU and only one
aggregator. The control blocks for the aggregators are located in LD1. A 64 char LDName setting is provided, see figure
below..

Precise time input to the relay from the international time standard, via either IRIG-B or PTP, is vital for correct syn-
chrophasor measurement and reporting. For IRIG-B, a DC level shift IRIG-B receiver must be used for the phasor
measurement unit to output proper synchrophasor values.
