12. Secure the sensor cable to the wall with an 8-inch by 0.14-inch
cable tie attached to a a plastic anchor every 18 to 24 inches
from the sensor to the monitor location. A loose cable could
present a manhole safety hazard or increase the potential for
sensor or monitor damage. If plastic anchors will not serve as
adequate anchors based on the structure of the manhole or wet
well wall, install ¼-inch x 2 ¼-inch bolts 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 cable.
 Tighten the cable tie around the cable, and cut off the
excess cable tie material.
Warning: Over-tightening the cable ties may damage the
sensor cable.
