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.
- CONNECTED: the moving part fully inserted the fixed part WITH
the connection both the power terminals and the sliding contacts
for the auxiliary circuits. 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.ckin -in tio n
WARNING
A) Open the circuit-breaker before carrying out any racking-in/out operation. The

.
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. 23) indicates DISCONNECTED. 23) indicates CONNECTED.
- 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.

DISCONNECTED position
Lift the moving part shown the paragraph (3) and insert the
fixed part guide, tilting shown figure 29. Remove the lifting
devices.
