6. If there is a shield around the telephone cable, it may be con-
nected to "G" on the terminal block. To avoid ground loops, we recom-
mend connecting the shield at the computer end only. A ground wire is
not necessary for proper operation of these units.
7. When you finish connecting the wires to the terminal block, the
assembly should resemble the diagram below:
8. Place the 2 halves of the strain relief assembly on either side
of the telephone wire and press together very lightly. Slide the assem-
bly so that it is about 2 inches from the terminal posts and press
together firmly. If your cable diameter is too small or too large for our
strain relief, please contact our technical support. We have strain relief
assemblies to accommodate most cable diameters.

9. Insert the strain relief assembly with the wire going through it
into the slot in the bottom half of the converter case and set it into the
recess in the case. If the telephone wire does not fit, please contact
our technical support. We have gauges to accommodate most wire
diameters.
10. BEND the top half of the case as necessary to place it over
the strain relief assembly. Do not snap the case together yet.
11. Insert one captive screw through a saddle washer; then insert
the captive screw with the washer on it through the hole in the DB-25
end of the case. Snap that side of the case closed. Repeat the
process for the other side. This completes the cable installation
process.
