(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.
For further details on pre-set Alpha codes, refer to the relevant unit documentation.
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.
See Figure 24
The mechanical keys are delivered pre-set and must not be altered. This prevents the
removable interface being placed on the wrong type of baseplate.
Do not manipulate the locking device. ABB will take no responsibility for
errors caused by manipulating locking devices.
