2-1. Transportation Precautions
DANGER
Never stand under the ACB that has been lifted or suspended by a lifter or lifting attachments. If the ACB body is accidentally
dropped, its weight may cause serious injury.
2-1-1. Transporting the ACB
Before transporting the ACB, make sure the breaker body is in the CONN. position. If the ACB has breaker fixing bolts, make
sure the breaker body is secured to the draw-out cradle with the fixing bolts.
When lifting the ACB, hold it using lifting attachments or wire ropes through the lifting holes. Take care that the position
switches, control circuit terminals, auxiliary switches, arc gas barrier and control terminal block cover which are shown in Fig. 1
are not damaged by the lifting rope. Lift the ACB carefully and gently. For transportation, place the ACB on a pallet and carry
slowly and carefully.
Avoid shock and vibration to the ACB during transportation.
Do not lay the ACB during transportation.
When transporting the ACB over great distances, crate it for protection against shock and vibration and secure the crate package
with wood or ropes.
When transporting the ACB while it is installed in a switchboard, you should fix the breaker body in the draw-out cradle with the
breaker fixing bolts (optional).
Lower the ACB onto a flat, level surface.
