No TC disconnected messages must appear; if they do,do not close the circuit-breaker immediately and make the correct connections.13.3.3 TestBefore putting into service, a test can be conducted by means of the specific "Auto test" function whichcan be activated on the PR123/DC. A positive result is shown on the display.Then a test can be conducted on the whole TC chain, again using the specific function (Trip test). A positiveresult is shown by the circuit-breaker opening.To run a Trip Test, press the “i Test” button and the “Enter”button simultaneously.Check the open or closed state of the circuit-breaker on the same "PR123/DC Test" screen, checking thatthe CB is closed and de-energized.13.3.4 Checking connectionsAfter making the initial settings, to ensure that the voltage sockets are properly connected on the power busbars, checkwhether the release come on when there is a voltage on the power input terminals and the CB is open and without any Vaux.If is not the case, there is no guaratee that the unit will function when powered from the busbar voltages without any Vaux.Contact ABB SACE.1/6CB openAuto TestTrip Test (disabled)CB statusTest
