• Moving the breaker body from the TEST position to
the ISOLATED position
1.
Open the ACB. (If the ACB remains closed, the draw-
out handle (Fig. 29 (1) ) cannot be inserted).
2.
Press the release button (Fig. 29 (6) ). The release
button will be locked depressed.
3.
Unlock the position lock lever (Fig. 29 (14) ) if locked.
4.
Insert the draw-out handle into the draw-out handle
insertion hole (Fig. 29 (4) ). And slowly turn
counterclockwise until a freewheeling sound is heard.
The position indicator (Fig. 29 (5) ) shows
“ISOLATED”. Turning the draw-out handle will unlock
the release button.
5.
Remove the draw-out handle.
• Moving the breaker body from the ISOLATED
position to the removed position
1.
Make sure the draw-out cradle (Fig. 29 (7) ) is
secured with mounting screws.
2.
Unlock the position lock lever (Fig. 29 (14) ) if locked.
3.
Push the rail stoppers (Fig. 29 (8) ) outward on both
sides of the draw-out cradle to unlock the draw-out rail
(Fig. 29 (9) ), and then uphold and pull out the rail until
it stops. The draw-out rail will be locked again by the
stoppers. (The breaker body cannot be drawn out
unless the rail is locked).
4.
Holding both the grips (Fig. 29 (10) ), draw out the
breaker body until it stops.
•
If the ACB is equipped with the communication
terminal block, pull out the hand connector (Fig. 29
(15) ) from the communication terminal block while
drawing out the breaker body. Make sure the hand
connector and control wire of the ACB are not
snagged when drawing out the breaker body again.
•
If the ACB is equipped with an optional auto-
discharging device (Fig. 29 (11) ), the closing springs
of the ACB will be automatically discharged with a
mechanical sound. This sound does not mean a
malfunction.
•
Do not leave the ACB body on the draw-out rail pulled
out.
5.
Use an optional lifter or lifting plate to transfer the
breaker body (Fig. 29 (3) ) to a safe place.
PUTTING THE BREAKER BODY BACK INTO THE
DRAW-OUT CRADLE
Never touch live terminal parts. Otherwise, electric
shock may result.
Do not leave the ACB body in the removed position.
The weight of the ACB may cause serious injury.
CAUTION
Make sure the draw-out cradle is secured with
mounting screws before inserting the breaker body
into the draw-out cradle. Otherwise, the insertion
operation may cause the breaker body or the draw-
out cradle to fall, resulting in damage to the ACB or
personal injury.
When retracting the draw-out rail into the draw-out
cradle, be sure to push the rail end. Do not hold the
hook pin, body stopper, or body stopper shaft. Doing
so may cause your fingers to be pinched, resulting in
injury.
Do not forcedly turn the draw-out handle clockwise
when the breaker body is in the CONN. Position.
Doing so may cause a malfunction.
If the ACB has the breaker fixing bolts, make sure the
bolts on both sides are securely tightened before
using the ACB. Loosened fixing bolts may cause a
malfunction of the ACB, in particular when it is
installed in such an area that is subject to strong
vibrations.
Use the separate draw-out handle to insert the breaker
body.
Putting the breaker body back to the ISOLATED
position
1.
Make sure the draw-out cradle (Fig. 29 (7) ) is
secured with mounting screws.
2.
Push the rail stoppers (Fig. 29 (8) ) outward on both
sides of the draw-out cradle to unlock the draw-out rail
(Fig. 29 (9) ), and then uphold and pull out the rail until
it stops. The draw-out rail will be locked again by the
stoppers. (The breaker body (Fig. 29 (3) ) cannot be
inserted unless the rail is locked).
3.
Use an optional lifter or lifting plate to place the
breaker body rollers (Fig. 30) on the draw-out rail (Fig.
30).
