DRAW-OUT OPERATION
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
If the ACB has the breaker fixing bolts, be sure to
loosen the bolts on both sides before draw-out
operation. Otherwise, damage to the ACB may result.
Make sure the draw-out cradle is secured with
mounting screws before drawing out the breaker
body. Otherwise, the draw-out 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.
Use the separate draw-out handle to draw-out the
breaker body.
• Moving the breaker body from the CONN. position
to the TEST position
1. Open the ACB. (If the ACB remains closed, the draw-
out handle (Fig. 29 (1) ) cannot be inserted).
2. Loosen the breaker fixing bolts (Fig. 29 (2) ), if used,
to unlock the breaker body (Fig. 29 (3) ).
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 the handle cannot be turned.
The position indicator (Fig. 29 (5) ) shows “TEST”.
• When the main circuit is disconnected at the
disconnect contacts, the breaker body will be slightly
pushed forward by the spring action of the main circuit
disconnect contacts. At this moment, a bang sound
will be heard. This sound does not mean a
malfunction.
• The ACB cannot be closed as long as the draw-out
handle is in the draw-out handle insertion hole. To
close the ACB e.g., for ON-OFF testing, remove the
draw-out handle.
