The LED indicators are current driven; therefore, no net current in a neutral and/or ground line
to the device will cause the respective indicator pairs to not glow or flash. For isolated 3-Phase
Delta or Wye applications, it is normal for the "GND" indicator pair to not flash since a current
path to ground is not present in an isolated system. Unless a phase is lost or an unbalanced
condition is created, current may likewise be insufficent for the "N" indicator pair to flash or
glow. This peculiarity results when the Phase-to-Phase voltages are balanced resulting in no net
current to a Neutral connection.
