(1) The key positions are common to CI867, CI868, CI871 and CI873. Hence caution must be
exercised in field replacement. Ensure that correct CI is inserted, especially in hot insert.
Ensure that the baseplate and the unit to be mounted have compatible Alpha codes.
Otherwise it may result in equipment damage. Any difficulty in installing a unit on a
particular baseplate indicates a difference in Alpha Code lock.
Do not manipulate the locking device. ABB will take no responsibility for
errors caused by manipulating locking devices.
