5.5.14Delete a Breaker

Removing a breaker from the configuration is required after moving or removing circuit breakers in the panelboard. This step must be performed before adding a breaker in the same position.

To delete a breaker:

•Run the Configuration program (see 5.5.1 - Starting the Configuration Program).

•If needed, select the panel and breaker view with the breaker to be deleted:

•In the Select Panel box, click on Panel A or Panel B.

•In the Select View box, choose Panel Breakers if the breaker is installed inside the panel- board or Auxiliary Breakers if located outside the panelboard.

•Right-click on the breaker position in the left pane. The selected breaker has a yellow outline.

•In the pop-up menu, click Delete.

•A confirmation message appears, as shown above. Select Yes to delete the breaker (or No to can- cel).

•Repeat as needed to delete other breakers.

•When finished, click Install to Unit to upload the changes to the Liebert LDM.

NOTE

The configuration changes will not be stored in the Liebert LDM until the Install to Unit button is clicked.
