About this detail

Terminal connections and test switches TS1 and TS2 serve a main relay control system. Test switch TS1 links phases A, B, and C along with neutral points and relay trip outputs. Test switch TS2 handles voltage transformer phases, neutral connections, relay inputs, and a -48VDC common power supply. Each terminal block is mapped with specific numbered points for meter and relay input-output integration.
