Always normalize the left and right sources and set the base volt-
ages on Phase 2 of the left and right sources after executing a
Config:
Restore Values command . The following parameters (even if the dis-
play shows correct values) also must be manually configured: Loss of
Source, Return of Source, Over Voltage, and Unbalance . Failure to do
so may result in erratic operations .
