Sensor Installation and Connection 3-53
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 a 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 the 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 an M6 x 55-mm anchor bolt instead.
