<p>The device has current supply connections for supplying the data terminal with electric power, a test element(s) between the current supply connections that defines a parameter between them, a switch element connected in series with the test element and a control line via which the switch element is opened by an external signal so that the connection between the first and second supply connections is interrupted via the test element. The device has at least a first and second current supply connection (3a,3b) for supplying the data terminal (10-12) with electric power, at least one test element (4) between the current supply connections that defines a parameter between them, a switch element (5) connected in series with the test element between the supply connections and a control line (5a) via which the switch element is opened by an external signal so that the connection between the first and second supply connections is interrupted via the test element. AN Independent claim is also included for the following: (a) a data network.</p> |
