Split-core current transformers are used to monitor AC current for various devices. The current transformer input takes a high-voltage current input and produces a proportional low-voltage, low-current signal for measuring and monitoring. Split-core current transformers are ideal for installing onto existing electrical wiring because they can snap around the individual conductors without disconnecting any cables. 

NOTE: Although the system comes with a 20 A and a 150 A current transformer, users can use any size current transformer rated up to a 655 A max rating, as long as the current transformer has a 333 mV AC output. 

## Installing the Current Transformers 

Observe the polarity when installing current transformers. Banner's current transformers indicate k (S1) as the source side and l (S2) as the load side, where source refers to the incoming power feed side to the device and the load side is the device side. 

Banner's CTs have an etched arrow to indicate the directionality for installation (k (S1) -> l (S2)). As shown in "Figure: Installing a current transformer relative to the power supply/motor" on page 2, the source is the AC power supply and the load is the Motor. The CT direction arrow must point toward the load. Banner's current transformers can be installed on any conductor in a 2- or 3-phase AC line. Current transformers should only be installed on a single conductor. For the correct installation, see "Figure: Installing a single conductor on the current transformer" on page 2.

## Configuration Instructions 

## Sensor Configuration Software 

The Sensor Configuration Software offers an easy way to manage converter Modbus settings, retrieve data, and visually show converter data. The Sensor Configuration Software runs on any Windows machine and uses an adapter cable (BWA-UCT-900, p/n 19970) to connect the converter to the computer. 

Download the most recent version of the Sensor Configuration Software from the Banner Engineering website: https:// info.bannerengineering.com/cs/groups/public/documents/software/b_3128586.exe.
