Probe Installation Pulling Wires for Probes
16
The direct burial method requires grinding a 1/4” to 3/8” wide by 1-1/4” deep groove (adding 1/4” of depth for each
additional cable) in the pavement surface, laying Veeder-Root supplied direct burial cable down in the bottom of the
groove, lay ing an expanded poly ethy lene foam backer rod over the cable(s), and then a placing a 1/4” to 1/2” bead of
Veeder-Root recommended silicone sealant over the backer rod to within a minimum of 3/8” below the pavement surface
[see Figure 10]. If you decide to use the direct burial method, you should order the Veeder-Root Direct Burial Cable
Preparat i on Kit , P/N 848100-500.

WARNING
Direct burial cable can be installed in hazardous locations where fuel and
vapor may be present. It is specifically designed for certain uses only. It must
be installed in the correct manner.
Installing the cable incorrectly or without proper precautions can result in fire,
explosion, electrical shock, hazardous conditions as well as equipment
damage or inaccurate inventory control.
Perform the following:
1. Use direct burial cable for intrinsically-safe wiring only. Do not use for
power wiring.
2. Do not share conduit for intrinsically-safe probes with wiring of any other
type or from any other system.
3. Maintain a physical separation of at least 2 inches between probe wiring
to all other wiring.
4. When cutting trenches for direct burial cable ensure that you do not cut
through existing fuel or wiring systems. Obtain as much site information
as possible before cutting the trench.
5. When grinding trenches in existing pavement for direct burial cables,
wear approved breathing and hearing protection, goggles, and gloves.
