7.1 Overview
7.1.1 Test Setup
The purpose of this testing description is to demonstrate the procedures necessary to
perform a complete functional test of all the 469 hardware while also testing firmware/
hardware interaction in the process. Since the 469 is packaged in a drawout case, a demo
case (metal carry case in which an 469 may be mounted) may be useful for creating a
portable test set. Testing of the relay during commissioning using a primary injection test
set will ensure that CTs and wiring are correct and complete.
