For advanced configuration and commissioning, you will connect to the relay via its front USB port and use software. This PC-based tool allows you to add or remove function groups, set protection parameters, and create the device's settings file. For instance, to configure a specific power directional function (ANSI 32) , you would use RM2. This requires first setting the CT and VT ratios and nominal power (Snom) in the software. The logical diagram for setting up this function is shown in the manual, with blocks for enabling the function, adjusting its settings, and configuring its output.
