2) Inserting into the disconnection position

Put the breaker to the switchgear or
cradle and push it slowly until it stops.
When it stops, set the manual lock handle
to the LOCK position. This is the
disconnection position. 

3) Inserting into the connection position

After checking that the breaker is open in
the disconnection position, insert the
handle into the head of the fixing screw
and turn it in a clockwise direction so that
the breaker moves to the connection
position.
When the breaker is in the connection
position check that the position indicator
displays "CONNECTION."

4) Withdrawing the breaker

First of all, open the breaker and put the
handle into the head of the fixing screw
and turn in a anticlockwise direction to
withdraw the breaker.
The position indicator will display
"DISCONNECTION" when the breaker
reaches the disconnection position.
To withdraw the breaker fully from the
cradle, put the manual locker to the
unlock state and pull the breaker out
slowly.

The Head of Fixing Screw

Improper operation of the breaker can
cause product damage.

The breaker can be withdrawn if the head
of the fixing screw isn't inserted in the
proper position.
Also, after withdrawing the breaker into the
disconnection position, the head of the
fixing screw must be in the proper position.
Otherwise the manual locker cannot move
to the unlock position.
Always check the location of fixing screw
for precise operation of the breaker.
