How do I use an ACB?
If the ACBs are of a draw-out type, insert the ACB bodies into the chassis to the connected position. Do not turn the ACB(s) on until it is in the connected position. If the ACB is a fixed type, unlock the ACB. After making sure the main circuit is not energised, check the operation of the ACB(s). Do not touch the interlock during operation.
How do you store an ACB?
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.
