Unit to Baseplate Alpha Code Lock
Since the units are very similar in design, baseplates have been given a two-part,
pre-set Alpha code locking device that prevents the installation of an incompatible
type of unit onto the baseplate should the Alpha codes not agree. All identical unit
types have the same factory pre-set, two-letter Alpha code installed prior to
delivery.
The following unit types have two-part, pre-set Alpha code locking devices
installed (see
Table 6 on page 54).
For further details on pre-set Alpha codes, refer to the relevant unit documentation
(see
Related Documentation on page 17).
Care must be taken to ensure that the correct unit is matched with the correct
baseplate, or damage to the equipment will occur. Care must be taken to ensure that
the correct unit is matched with the correct baseplate, or damage to the equipment
