It is required that the cable’s shield be continuous across the entire length of the cable, including at the termitions. The figure below shows the recommended method for folding the braided shield back before inserting the cable into a metallized cover. Split–Ring Ferrule Cable Jacket Ground Attach to Pin 1 for custom length cables Conductors Foil & Braid (to be folded back over ferrule and ground ) a45524 OR Fold back for custom Wye cables. * * See “Alert for Users of Early Remote Baseplate Versions” for description of when to attach drain to pin 1. Figure B-2. How to use Split-Ring Ferrules for Foil and Braided Cable Shield For typical industrial applications, all expansion and remote baseplate cables can be de with plastic shell covers and should be d as shown in Figure 10-19. In either case, pin 1 should be d into both ends of the custom length cable and the recommendations listed below should be followed for the Wye cables treatment in the remote (IC693CHS392/399) baseplates. When using 100% shielded cables all local ( and expansion) baseplates in the system must be solidly referenced to the same ground point or a potential difference between baseplates could disturb sigl transmission. Alert for Users of Early Remote Baseplate Versions In early remote baseplates versions, IC693CHS393E (and earlier) and IC693CHS399D (and earlier), it is necessary to remove pin 1 of the ting cable where the cable plugs into the baseplate. This means that when using a factory de Wye cable, such as IC693CBL300, you must break pin 1 out of the le 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. I/O Cable Data Sheets C GFK-0898F Appendix C – I/O Cable Data Sheets C-7 Remote baseplates IC693CHS393F (and later) and IC693CHS399E (and later) have a change inside the baseplate which elimites the need to remove pin 1 from the ting cable. When using factory de Wye cable with these baseplates, it is t necessary to remove pin 1 from the cable. Custom built Wye cables for these baseplates can be de using either Figure 10-20 or Figure 10-21. Figure 10-21 shows how the standard (factory de) Wye cables are de. By removing pin 1 in custom built Wye cables de for the earlier versions of remote baseplates, the pin 7 (0V) sigl reference origites in the in () baseplate. In these earlier versions of the remote baseplates, pin 1 was tied to pin 7 (0V) and also AC coupled to the remote frame ground. When using these baseplates in combition with the 100% shielded Wye cables, the pin 7 (0V) reference would be improperly DC coupled to the remote frame ground through the D-subminiature connector shell, which is DC coupled to the remote frame ground. In the remote baseplates IC693CHS393F (and later) and IC693CHS399E (and later), the pin 1 shield sigl is DC coupled to the remote frame ground and t attached to pin 7 (0V).
