Figure 13-8: ACI Card Wiring & Cabling Diagram
In the VR-2745 ACI Card, you have three methods of AC current
measurement wiring signals:
 Mode 1: 6xWire 3xCT or 3xPhase Measurement Mode, it is for
normal AC 3x phase measurement in 6 wire individual mode. For
setup this mode you must un-jumper J2,J3 and J4.
 Mode 2: 8xWire 4xCT Measurement Mode, it is for measuring 4
independent AC current inputs. Each CT individually metering
current and wired to the back plane of Card. For setup this mode
you must un-jumper J2, J3 and J4 in back of Card.
 Mode 3: 4xWire 3xPhase Measurement Mode, it is for normal
current measurement of 3x Phase AC circuit. Please be informed
that in this case the common of CTs also can be measured in
Card as neutral/common current. For setup this you must jumper
J2, J3 and J4 in back of Card. (Mode 3 is default mode).
