Sensor Installation and Connection 3-65
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
restrict the air tube, causing incorrect pressure depth
readings.
2. Secure the cables with a cable tie and plastic anchor every 18
to 24 inches (457 to 610 mm) along the pipe crown (when
necessary) from the ring to the manhole. If plastic anchors
will not serve as adequate anchors based on the structure of
the pipe, install M6 x 55-mm anchor bolts instead.
3. Secure the cables every 18 to 24 inches (457 to 610 mm) up
the side of the manhole to the monitor location. Loose cables
could present a manhole safety hazard or increase the
potential for sensor or monitor damage to occur. If plastic
anchors will not serve as adequate anchors based on the
structure of the manhole wall, install ¼-inch x 2 ¼-inch ( M6
x 55-mm) anchor bolts instead.
Warning: Make sure the connector-end of the sensor is
not kinked, does not contain moisture, and includes an
attached dryer tube filled with active blue desiccant.
