Wiring the CTs to the

AcquiSuite

™

Ally Meter

The image below is the counterpart to the service panel illustration and indicates how to connect CTs to
the Ally meter for each service type. For service types that are not specifically listed, it is recommended

to choose “single phase” service and configure each

channel individually. Three phase loads are

illustrated on the left and split phase loads on the right as an example only. Elements are fully
interchangeable on the meter.
