9-6 Installing Your NRU
NRU Checks After Power Up
1. Verify that the incoming phase-to-phase line voltage is within the
specified tolerances:
2. The common DC bus voltage will vary based upon the 3-phase
AC input voltage. Verify that the common DC bus voltage is
within the tolerances:
Note: We suggest that you check the DC bus voltage at the DC
bus energized board as shown in Figure 9.2.

Where to Check the DC Bus Voltage
!
ATTENTION: You must not proceed with regular
operation if the NRU fails any of the checks described
in this section. Failure to do so may result in personal
injury and/or equipment damage.
