Use the following procedure for connecting braided power cable:
Connecting Power if Using a Ferrite Core
1. If using the ferrite core, carefully remove 7" of the outer blue insulation and 6.5" of braid from the cable. If
you are NOT using the ferrite core, proceed to step 14.
2. Remove the domed cap, reducing gland and metal sleeve from the center cord grip of the indicator. Place
them on a table or other work surface.
3. Remove the domed cap and reducing gland from the 320IS parts kit.
Note that the domed cap and the reducing gland from the parts kit have larger holes. Do not confuse these
part with the parts removed from the cord grip of the indicator.
4. Take the metal sleeve (from step 2), and insert it into the reducing gland taken from the parts kit.
5. Place the domed cap and the reducing gland, that were removed from the 320IS cord grip, into the parts kit
(to be used as spares).
6. Thread the DC cable through the domed cap, then through the reducing gland/metal sleeve combination.
7. Lower the reducing gland assembly so that the end of the metal sleeve is at the edge of the insulation and
fold the braid over the metal sleeve. See Figure 1. Trim the braid if necessary.
8. Trim the white colored wire back to match the end of the braid.
9. Thread the cable through the cord grip stem.
Note
The chassis ground is made through the braid compressed between the metal sleeve and the cord grip stem.
10. Lower the domed cap onto the cord grip stem and tighten until a small swelling of the rubber of the
reducing gland appears between the domed cap and cable. See Figure 2.

11. Thread the green and brown wires two times through the ferrite core from the parts kit. Keep the ferrite
core as close as possible to the backplate.
