7.3. Racking-in/out operation

WARNING

A) Open the circuit-breaker before carrying out any racking-in/out operation.

B) The circuit-breaker (moving part) and fixed part are fitted with a lock which prevents the fixed part from being racked into the

circuit-breakers with a different rated current: the congruence of the anti-racking-in lock must be checked by the operator

before carrying out the racking-in operation to avoid any unnecessary stress.

C) Before the racking-in operation, remove any padlock on the segregation shutter of the isolation terminals on the fixed part.

WARNING ELECTRICAL SHOCK HAZARD: Ensure that the circuit-breaker is either disconnected from all power

sources and that the circuit breaker is open before performing any racking-in/out operation.

NOTE

In relation to the fixed part, the circuit-breaker (moving part) can

take up different positions, identified as follows:

- DISCONNECTED: the moving part is inserted in the fixed

part WITHOUT any connection between the power terminals

and WITHOUT coupling the sliding contacts for the auxiliary

circuits: in this position all electrical operation of the circuit-

breaker is prevented. On the front the indicator (9, Fig. 23)

indicates DISCONNECTED. The switchgear compartment

door can be closed.

- TEST ISOLATED: the moving part is inserted in the fixed part

WITHOUT any connection between the power terminals, but

WITH the sliding contacts coupled for the auxiliary circuits. In

this position, the circuit-breaker can be operated for the offline

tests. The indicator (9, Fig. 23) indicates TEST ISOLATED.

- CONNECTED: the moving part is fully inserted in the fixed

part WITH the connection of both the power terminals and the

sliding contacts for the auxiliary circuits. The circuit-breaker is

operational. The indicator (9, Fig. 23) indicates CONNECTED.
