On the front the indicator (9, Fig.7. Push the moving part far the stop the fixed part. - TEST ISOLATED: the moving part inserted the fixed part WITHOUT any connection between the power terminals, but WITH the sliding contacts coupled for the auxiliary circuits. - CONNECTED: the moving part fully inserted the fixed part WITH the connection both the power terminals and the sliding contacts for the auxiliary circuits. Close the compartment door. The position reached stable and allows for any inspections the circuit-breaker. 23) indicates CONNECTED. this position, the circuit-breaker can operated for the offline tests. 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. The circuit-breaker operational. 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. 23) indicates DISCONNECTED. The indicator (9, Fig. 18/158 . Model L2234 Apparatus Scale L 2778 Doc No' 1SDH000460R0002 Page No. 23) indicates TEST ISOLATED. The switchgear compartment door can closed. Remove the lifting devices.3 Racking-in/out operation WARNING A) Open the circuit-breaker before carrying out any racking-in/out operation. a itio fix e DISCONNECTED position Lift the moving part shown the paragraph (3) and insert the fixed part guide, tilting shown figure 29. N S 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 ofthe circuit-breaker prevented. The indicator (9, Fig
