2-1-2. Transporting the breaker body
Use an optional lifter or lifting plate to transfer the breaker body.
When transporting the breaker body on a lifter, move the lifter with the lifter fork held at the lowest possible position.
Take care not to exert forces on the front cover and the control circuit contacts shown in Fig. 2 . Otherwise, a deformation or
damage may result.

2-1-3. Transporting the draw-out cradle
When transporting the draw-out cradle, hold it using lifting attachments or wire ropes through the lifting holes or carry it by the
portions (4 points) marked with the arrows shown in Fig 3. When carrying the draw-out cradle, take care not to exert forces on
the arc gas barrier, the draw-out arm, the position switches, the auxiliary switches, the control circuit terminals, the control

2-2. Storage Precautions
It is recommended that the ACB be used as soon as you have received it. If it is necessary to store the ACB, note the following:
Store the ACB in a dry indoor location to prevent condensation due to sudden changes in ambient temperature. Condensation has
a harmful effect on the ACB insulation.
Store the ACB in a clean place free of corrosive gases and dust. In particular, exposure to a mixture of moisture and cement dust
may cause corrosion damage to metal parts of the ACB.
Place the ACB on a flat, level surface in its normal position (Do not lay the ACB).
Do not place the ACB directly on the floor. Do not stack the ACBs during storage.
