Remove existing protector and
enclosure from building, if installed.
Step 2:
Select desired mounting location.
Select appropriate mounting features
for secure mounting: external
mounting ears or vertical conduit
mounting.

Service Hookup
Step 1:
Open telco cover using a pin and hex tool to turn the
two telco screws one-quarter turn. Remove the middle
rubber grommet and pierce with sharp object (Figure 6).
Feed drop wire and ground wire through grommet and
replace grommet.
Figure 6
NOTE:
Drop wire terminals are Insulation Displacement Connectors (IDC); wires need not be stripped. The
terminals are identified with a “T” for tip and an “R” for ring.
Step 2:
Connect ground wire according to local code or practice using a #6 AWG ground wire.
Step 3:
Unscrew the stuffer on the USP until it is fully open
(Figure 7).
Step 4:
If using 22-24 AWG wire, it is necessary to use
the wire guide to facilitate proper wire insertion. If
wire guide has been misplaced, contact Corning
Customer Services to order replacement guides.
If using 18 AWG wire, remove the wire guide from the
protector holes. (It is recommended to retain the wire
guide in case it is needed later.)

Screw the stuffer back down to make contact. Gently tug on all wires to check connection.
