Figure 10-19. Earlier Versions of Remote Baseplate Custom WYE Cable Wiring Diagram
Note: In remote baseplates, IC693CHS393E (and earlier) and IC693CHS399D
(and earlier), it is necessary to remove pin 1 of the mating cable where
the cable plugs into the baseplate. This means that when using a factory
made Wye cable, IC693CBL300, you must break pin 1 out of the male
end where it plugs into the remote baseplate before using it with one of
these baseplates. Custom built Wye cables for these baseplates should
be built using Figure 10-20. See the section “Alert to Users of Early
Remote Baseplate Versions” for more details.
