The circuit-breaker operational. The position reached stable and allows for any inspections the circuit-breaker. 23) indicates CONNECTED. Remove the lifting devices. a) Positioning the moving part the fixed part the DISCONNECTED position Lift the moving part shown the paragraph (3) and insert the fixed part guide, tilting shown figure 29. C) Before the racking-in operation, remove any padlock the segregation shutter the isolation terminals the fixed part. The manual connection must allow the edge (E) the circuit-breaker guide slide under the blocks (D) the fixed part. 28 NOTES In relation the fixed part, the circuit-breaker (moving part) can take up different positions, identified follows: - DISCONNECTED: the moving part inserted the fixed part WITHOUT any connection between the power term inals and WITHOUT coupling the sliding contacts for the auxiliary circuits: in this position all electrical operation the circuit-breaker prevented. The switchgear compartment door can closed. 23) indicates TEST ISOLATED. Push the moving part far the stop the fixed part. The indicator (9, Fig. The indicator (9, Fig. 17/108 . On the front the indicator (9, Fig. Close the compartment door. B) The circuit-breaker (moving part) and fixed part are fitted with lock which prevents the fixed part from being racked into the circuit-breakers with different rated current: the congruence the anti-racking-in lock must checked the operator before carrying out the racking- in operation avoid any unnecessary stress
