⑥ Unlock, release your hands from the lock plate, and
rotate the drawout handle clockwise.

Do not draw out during the insert operation. The
drawout position may not be indicated correctly. If that
is the case, pull out the breaker to the DISCONNECT
position once, and then retry the insert operation.

Insert the lock plate, and rotate the drawout handle
clockwise. When the breaker is inserted to the CONNECT
position, the lock plate is protruded automatically,
completing the insert operation. At this time, the drawout
position indicator shows the CONNECT position. For all
breaker types, the operation load becomes heavy during
operation from the TEST position to the CONNECT position
or at the main circuit junction insertion position, but this is
not a fault.
CAUTION
Be sure to insert until the lock plate is protruded. If it
is not protruded, the connection may be incomplete.
(Caution)
(a) After completing the insertion, do not rotate the
drawout handle.
(b) The drawout position indicator shows the position
(CONNECT, TEST) when the lock plate is protruded.
When the lock plate is unlocked, it shows a
reference position.
(c) The breaker cannot be closed with the drawout
handle inserted.
