Remote baseplates IC693CHS393F (and later( and IC693CHS399E (and later) have a change
inside the baseplate which alleviates the need to remove pin 1 from the mating cable. When using
factory made Wye cable with these baseplates, it is not necessary to remove pin 1 from the cable.
Custom built Wye cables for these baseplates can be made using either Figure 10-20 or Figure 10-
21. Figure 10-21 shows how the factory made Wye cable are made.
