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 input terminals on the
AcquiSuite™ Ally, 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.
•
Current and voltage inputs must be installed ‘in phase’ for accurate readings (e.g. CT1
on Line 1, CT2 on Line 2) Orientation is critical: Ensure that all CTs are properly oriented
with the line and load, as marked. Failure to install CTs in the correct orientation and on
the correct phase will lead to inaccurate meter readings.
