ASSEMBLY INSTRUCTIONS 40-1

The following suggested procedure serves as a guide for
®
proper assembly and installation of Glenair TAG Ring Back-
shells. Actual termination and assembly methods will de-
pend on the accepted techniques of the user. It is recom-
mended that trial samples of appropriate cables or harnesses TAG Ring Nut (2)
be used to determine proper trim dimensions of the conduc- Backshell (1)

These instructions are based on using a self-pigtailing tech-
nique for the individual shields, with the location at which the
conductors are extracted through the shields to be determined
by the particular connector involved, as well as backshell Strain Relief (3)

Solder sleeves and ground wires may be used as an alter-
nate method of commonly grounding the individual conduc-
tor shields. A slight alteration of the following instructions will
permit easy termination of these ground wires.
a. Measure length of backshell (1) and determine length of
conductor needed to terminate to connector and locate FIGURE 1

tion of the TAG Ring backshell.
