Sensor Installation and Connection 3-43
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.
Note: Do not secure a wireless communication antenna
cable with the sensor cables! Refer to Setting Up Wireless
Communication in Chapter 4, Communication, for
information on securing the antenna cable in the manhole.
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 by 0.14-inch
cable tie attached to a plastic anchor installed at the top of the
pipe.
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 bolt instead.
 Drill a 3/8-inch hole in the pipe crown.
 Drive the plastic anchor into the pipe with a hammer until
flush and secure.
 Run the cable tie through the loop in the plastic anchor and
around the cables.
