7.2 Application example and its connections
This chapter presents an application example for the motor protection IED.
Since three line-to-neutral voltages and the zero sequence voltage (U4) are connected, this application
uses the voltage measurement mode "3LN+U0" (see the image below). Additionally, the three phase
currents and the residual current (I01) are also connected. The digital inputs are connected to indicate
the breaker status, while the digital outputs are used for breaker control.

7.3 Two-phase, three-wire ARON input connection
This chapter presents the two-phase, three-wire ARON input connection for any AQ-200 series IED
with a current transformer. The example is for applications with protection CTs for just two phases. The
connection is suitable for both motor and feeder applications.
