12. Thread the green and brown wires two times through the ferrite core from the parts kit. See Figure 2-4 as
an example picture.
13. Connect the green and brown wires to the connector for CN1, observing polarities. See Table 2-3 below.
14. Plug the connector onto CN1.
15. Connect the AC power.
2.4.2 Braided Power Cable Connection Without Ferrite Core
Use the following procedure for connecting a braided power cable without a ferrite core.
1. If not using a ferrite core, carefully remove 3" of outer blue insulation and 2.5" of braid from the cable.
2. Remove the domed cap, reducing gland and the metal sleeve from the center cord grip of the indicator.
Place them on a work surface.
3. Remove the domed cap and reducing gland from the 320IS Plus parts kit.
The domed cap and reducing gland from the parts kit have larger holes. DO NOT confuse these parts with
the parts removed from the cord grip.
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 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 (Figure 2-2). Trim the braid if necessary.
8. Trim the white wire back to match the end of the braid.
9. Tin the end of the green and brown wires.
10. Thread the cable through the cord grip stem.
Chassis ground is made through the braid compressed between the metal sleeve and the cord grip stem.
11. 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 2-3).
12. Connect the green and brown wires to the connector for CN1. Observe polarity. See Table 2-3.
13. Plug the cable into CN1.
14. Connect the AC power.
2.4.3 Braided Load Cell Cable Connection
Use the following procedure for connecting braided load cell cable:
If Using 6 Wire Load Cell Cable
1. Carefully remove 8" of outside insulation and 7 1/2" of braid from the load cell cable.
2. Remove the metal domed cap, reducing gland and metal sleeve from the left metal cord grip. Place them
on a work surface.
3. Remove the reducing gland and metal domed cap from the 320IS plus parts kit.
These have a larger hole than those removed from the cord grip — DO NOT confuse them.
4. Take the metal sleeve from step 2, and insert it into the reducing gland taken from the parts kit.
5. Retain the cord grips.
