Installation (See Figure 2)
1. Remove the unit from the packaging and inspect it
carefully for damage. If found damaged, obtain another.
2. Install the TII 372-S/372-S2 module in the NID under the
lower nut of the ground stud and tighten securely. For
illustration purposes Figure 2 shows the 372-S/372-S2
protector mounted in slot 2.
3. Pass the appropriate earth ground wire through the CO
(central office) side grommet of the NID and connect it to the
ground stud.
4. Run and connect the earth ground wire to the approved
ground source making the run as short and straight as
possible.
5. Pass the service wire through the CO side grommet of the
NID.
6. After stripping the jacket and appropriately terminating the
shield of the service wire to the G protector clip, secure the
G protector clip under the washer and nut of the NID ground
terminal as shown in Figure 2.
7. Disengage “CO” side rocker using a ¼” flat screw driver in
the slot provided on top of the rockers.
8. Untwist about 1” of CO (service) side, transmit and
receive cable pairs. Insert the unstripped wires through the
rocker wire guide holes until all wires hit the back end of the
rocker.
9. Hold the wires in place and lower the rocker to its
terminated position-using thumb. (A flat ¼” screw driver could
be used to assist in terminating wires.)
10. Disengage “customer” side rocker.
11. Untwist about 1” of red/green and yellow/black wire pairs
from the 100 Base-T subscriber module. Guide wires
through the wire guide holes on the customer side rocker.
Make sure all the wires are fully seated.
12. Follow Step 9 above to terminate “customer” side wires.
13. Route wiring in NID as to avoid sharp bends. Close
