9.4 EXTRACTION OPERATION

CAUTION!
1)Stop the handling when the insertion/extraction locking device jumps.
2)Insert or extract by moving the rod to the right or left when the locking device cannot be inserted.

9.4.1 Extraction procedures

1. Hold down the OFF key and the circuit breaker in the trip condition, and insert the rod into the circuit breaker body.
2. Make sure the extraction rod is inserted correctly, then push the locking plate and turn the extractor rod
clockwise to insert into the circuit breaker.
3. When the circuit breaker reaches the TEST position, the locking plate protrudes automatically, and the extractor
rod is locked.
4. Push the locking plate and rotate the extractor rod counterclockwise again until the locking plate protrudes.
At this moment, the extraction operation is completed, and the indicator shows the DISCONNECTED position
(DISCONNECTED).
5. The circuit breaker marked 'DISCONNECTED' can be safely separated from the truck by removing the insertion/
extraction rod and releasing the right and left latches.
6. Use the lifting hook to separate the circuit breaker from the truck.
