2.1 Meter Printed Circuit Board (PCB)
AC power, current transformers (CTs), and RS485 are connected to
the Meter PCB.
The AC power connections are labeled from 1 to 5 on the lower left
PCB corner, above the label “MAIN POWER INPUTS”.
The current transformers (CTs) connections are labeled 6 to 8 in
the lower middle of the PCB, above the label “CURRRENT SENSOR
INPUTS”. Connected CTs must match the related AC power voltage
input.
•
CT A (CURRENT SENSOR INPUTS) must measure the current of
phase A (MAIN POWER INPUTS)
•
CT B (CURRENT SENSOR INPUTS) must measure the current of
phase B (MAIN POWER INPUTS)
•
CT C (CURRENT SENSOR INPUTS) must measure the current of
phase C (MAIN POWER INPUTS)
RS485 connections are labeled 9 to 10 in lower right hand of the
PCB above the label RS485.
