Securing The Sensor Cables In The Pipe And Manhole - ADS TRITON+ Installation, Operation And Maintenance Manual

Securing the Sensor Cables in the
Pipe and Manhole
Securing the sensor cables from the ring (or band, when
applicable), along the pipe crown, and up the manhole helps
prevent debris from collecting on sagging cables or between the
cables and the pipe crown.
Do not allow sensor cables to hang down in the pipe or sag in the
manhole. Loose cables could present a safety hazard in the
manhole or increase the potential for sensor or monitor damage to
occur. The cables should be secured along the pipe crown and
manhole wall under all circumstances.
Secure the cables from the ring (or band) to the monitor location in
the manhole in the following way:
1. Neatly bundle the cables together with an 8-inch (4-mm x 200-
mm) cable tie attached to a plastic anchor installed at the top of
the pipe.
Drill a hole of the appropriate size for the shank of the
plastic anchor in the pipe crown. Refer to instructions with
the anchors.
Drive the plastic anchor into the pipe with a hammer until
it is flush and secure.
Run the cable tie through the loop in the plastic anchor and
around the cables.
Tighten the cable tie around the cables and cut off the
excess cable tie material.
Note: If a plastic anchor will not serve as an adequate
anchor for securing the cable bundle based on the structure
of the pipe, install a ¼-inch x 2 ¼-inch (M6 x 55-mm)
anchor bolt instead.
Warning: Do not over-tighten the cable ties or kink the
sensor cables! The depth cable sheathes two components:
the electrical cables that operate the sensor and an air tube
that ventilates the sensor (when applicable). Over-
tightening the ties or kinking the cable can damage or
