Preparation of trenches

4. Place cable marker tape in the trench 7.5 cm (3 in.) above the sensor cable (optional).
5. Finish backfilling the trench.
Standard cable spacing (dual trench)
For dual trench installation, bury the sensor cable directly in native soil. Before burying the cables,
ensure that there are no rocks or debris mixed in with the soil that could potentially damage the
sensor cables.
Note Do not cover the ends of the sensor cables with soil, as ferrite beads,
connectors, and decouplers must be installed.
Note Before backfilling the trench to ground level, install the ferrite beads and
connectors, but do not seal the heatshrink at this time (see Installing
cable fittings on page 121). Next, do the cable tests (see Cable tests on
page 146) and then do a sensitivity profile to verify the installation (see
OmniTrax calibration - Sensitivity Profile and Transmitter Power
on
page 197).
