CAUTION!
Do not use a knife to cut the opening in the rubber grommets. This
can result in an excessively large hole and compromise the integrity
of the unit and allow moisture into the unit.
1. Refer to Figure 4 and insert the ground wire through the rubber
grommet.
2. Remove 1 inch of the insulation jacket from a 6 AWG
minimum copper ground wire.
Figure 4. Inserting the Ground Wire
3. Loosen the set screws on the ground bar.
4. Insert the ground wire in the ground bar and tighten set screw.
5. Route the ground wire 12 inches below finished grade by the
shortest and most direct route to the AC power ground system to
connect to a ground. Ensure the wire is free of any sharp bends.
6. Attach the ground wire to the side of the subscriber’s premises with
stainless steel half moon clamps or tie-wrap the ground wire to the
riser conduit of the Buried Fiber Drop.
7. Clean the Multi Grounded Neutral (MGN) connector with emery
cloth to ensure a stable connection.
8. Attach the ground wire from the NID to the MGN connector with the
appropriate UL approved ground clamp/fitting.
9. Coat the connection with a metal corrosion preventative.
10. Attach a Warning Ground Tag to the grounding connection.

CAUTION!
Align the captive screw on the bottom of the ONT with the screw hole
on the Ground Bar and tighten (refer to
