Wiring the AcquiSuit e™ Ally Meter in a 4-wire, 3 ɸ Service Panel
Illustrating the intended wiring configuration for each of the Service Types
available in the Service drop- down list under “Meter Setup”
Note: The AcquiSuite ™ Ally Meter Series uses the “Neutral” Terminal as a
voltage reference. For systems without a neutral conductor, Leviton
suggests connecting a ground wire to this terminal. If the neutral terminal
is left open, L-L measurements will be accurate, but L-N measurements
may not be symmetric. If a ground wire is connected to the Neutral
terminal, <2mA will flow into the ground wire.
