- Once the connection between the relay and PC has been installed, check that there are no alarm signals from the relay; otherwise,
consult the paragraphs ‘Error Messages’ and/or ‘Troubleshooting’ in this manual.
- In normal operating conditions the trip test and the autotest can be run (depending on the type of relay); for future checks, we advise
inserting the current date in the User Data and/or Tag Name area. These data will be stored inside the relay.
- Remove the Ekip T&P cable adapter from the relay.

- Refit each part and always reconnect the auxiliary supply.
- Refit the cap as indicated in figure 46.

Check that the interlock devices have been correctly installed and operate correctly between adjacent and superimposed circuit-
breakers (if present). The operating test cannot be run in the Test or Extracted positions.
8.4.12. Withdrawable
In the withdrawable versions, check the operational efficiency of the insertion and extraction of the circuit-breakers from the fixed part,
performing the movement by means of the operating lever supplied and checking that the shutters for segregating the parts carrying
live voltage are closed after extraction. Check correct operation of the inserted and extracted circuit-breakers lock devices (if present).
