Communication 4-25
Running the cable and conduit from the manhole to the EMU/power source
7. Provide enough slack in the cable at the manhole end to allow
removal of the monitor from the manhole during service
activities.
Note: Do not connect the cable to the monitor at this
time!
8. Provide approximately 1016 mm (40 in) of excess cabling at
the EMU/power source location.
9. (applies only to applications requiring conduit) Use urethane
foam or a sealing fitting to form a seal between the
communication cable and conduit at each end of the conduit.
This will prevent sewer gases from entering the pedestal,
moisture from entering the conduit during a surcharge, and
inflow from entering the manhole.
10. Route the communication cable into the bottom of the hole at
the EMU/power source location. Verify that there are still
1016 mm (40 in) of the communication cable exposed, from the
bottom of the hole (where the cable enters the hole) to the end
of the cable.
11. Backfill the dirt in the hole to grade level at the EMU/power
source location, while tamping with a hammer. Restore the
landscape as necessary.
