Wiring the AcquiSuite™ 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, Obvius 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.
