Cable Termination Instructions
Follow these steps to prepare and terminate cables connected to the Tropos 7320 router:
1. Strip off the outer sheath of cable to expose 6 inches of the inner cable or twisted pairs. The
shield may be armored, braided or foil type depending upon cable type (see
Table 33 ).
2.
For armored or braided cable, remove all but 1/2 inch of the armor or braid.
— Remove waxy residues on the shields of “flooded” type cables.
— For foil shielded cable, remove all but 1/2 inch of the foil, and fold the foil part back onto
the outer sheath. Most foil shields are conductive on the inner side, as the outer side
typically has a plastic coating.
— The exposed conductive surfaces will ground to the conductive contacts inside the cable
gland.

Cable Components
3. Run the stripped part of the cable through the cable gland ( Figure 34 ). Make sure that the
braided conductive shield of the cable makes contact with the conductive contacts of the
cable gland (
Figure 34 ).
4. Attach the cable gland by first tightening the gland base into the access cover. Then tighten
the gland cover to constrict the weather-tight grommet around the outer jacket of the cable,
thereby creating a weather-tight fitting.
