Note: conduit requirements are dependent on local electrical regulations.
For probe-to-console wiring, shielded cable is required regardless of
conduit requirements.
WARNING:
Substitution of components may impair intrinsic safety.
Circuitry within the TLS-HLD Console barrier forms an intrinsically safe,
energy-limited system. This system makes TLS-HLD probes safe for use
in a Class I, Group D hazardous location. TLS-HLD probe wiring is
intrinsically safe only when connected to Veeder-Root's TLS-HLD
Console. Reference Console Form Number 8469 and Probe Form
Numbers 8462, 8463, 8468, and 8473.

Site Considerations
National Electrical Code Compliance
National Electrical Code Compliance
The following information is for general reference and is not intended to replace recommended National Electric Code
(NEC) procedures. It is important for the installer to understand that electrical equipment and wiring located in Class I,
Division 1 and 2 installations shall comply with the latest appropriate articles found in the National Electric Code (NFPA
70) and the Automotive and Marine Service Station Code (NFPA 30A), or other local code such as the CEC,
Canadian Electrical Code..
PROBE- TO-CONSOLE WIRING
Shielded Cable or Veeder-Root Direct Burial Cable Required
To ensure the best operating systems available, Veeder-Root REQUIRES the use of shielded cable for all probes
regardless of conduit material or application. In these installations, shielded cable must be rated less than 100 picofarad
per foot and be manufactured with a material suitable for the environment, such as Carol
8760.
Note: Throughout this manual, when mentioning any cable being used for probe-to-console wiring, it will be referring to
shielded cable.
Wire Length
Improper system operation could result in undetected potential environmental and health hazards if the probe-to-console
wire runs exceed 1000 feet. Wire runs must be less than 1000 feet to meet intrinsic safety requirements.
™
C2534 or Belden™ 88760,
Splices
Veeder-Root recommends that no splices be made in the wire run between a probe junction box and the console. Each
splice degrades signal strength and could result in poor system performance.
Wire Gauges - Color coded
• Shielded cable must be used in all installations. Probe-to-console wires should be #14 - #18 AWG stranded copper
wire and installed as a Class 1 circuit. As an alternate method when approved by the local authority having
jurisdiction, #22 AWG wires such as Belden 88761 may be suitable in installations with the following provisions:
- Wire run is less than 750 feet
- Capacitance does not exceed 100 pF/foot
- Inductance does not exceed 0.5 μH/foot
• Wires carrying 120 or 240 Vac from the power panel to the console should be #14 AWG copper wire for line, neutral
and chassis ground (3); and #12 AWG copper wire for barrier ground (1).
PROBE JUNCTION BOXES
Weatherproof electrical junction boxes with a gasketed cover are required on the end of each probe conduit run at the
manhole location. Gasketing or sealing compound must be used at each entry to the junction box to ensure a waterproof
junction. The interior volume of each junction box must be a minimum of 16 cubic inches.
Veeder-Root recommends the following junction box or equivalent:
• Appleton Electric Co. - JBDX junction box, JBK-B cover, and JB-GK-V gasket.
• Crouse-Hinds Co. - GRFX-139 junction box, GRF-10 cover, and GASK-643 gasket.

Probe Wiring Safety Issues
WARNING
Probes operate in area s wher e flammabl e l iquid s and ex plos ive v apors may be
present.
Improper installation may result in fire or explosi on causing serious injury or
death.
Practice the following:
1. Read thoroughly and f ollow the instructions shipped with each probe.
2. Probe wiring must enter the consol e only through their designated a reas.
3. Power wires and condui t must not enter the intr insically safe
compartment of the console.
4. Substitution of components may impair intri nsic safety.
Wiring between the console and the probes is of limited electrical power so that there is insufficient energy to ignite fuel.
In the console, the low power probe wiring is considered intrinsically safe because it is physically isolated f rom all high
power wiring. To maintain the integrity of this safety feature probe wiring can not share the same conduit with power
wiring. In addition, probe cables can only enter the console through the designated intrinsically safe area knockouts.
If the TLS-HLD System is being retrofitted into a paved site, you can cut grooves in the pavement, run direct burial
cable to the probes, and then seal over the cable grooves, subject to approval of the local authority having jurisdiction.
Before trenching, you should diagram all conduit runs between the console’s intended location and its deployed probes.
Your site diagram will help you calculate conduit and wiring lengths, and necessary quantities of junction boxes, sealing
boxes, clamps, brackets, etc.
Throughout this planning process and in the actual installation, you must follow all latest National Electric Codes, and
applicable federal, state, and local codes as regards conduit type, depth below grade, sealing, grounding, wire capacities,
direct burial (if permitted), etc.
Selecting a Console Location
WARNING
Explosive vapors or flammable liquid s could be pre sent near locations wher e
fuels are stored or being dispensed. The TLS-HLD Console is not explosion
proof.
An explosion or fire resulting in serious injury or death, property loss and
equipment damage could occur if the console is installed in a volatile,
combustible or explosive atmosphere (Class I, Division 1 or 2).
Do not install this c onsole in a v olati le, comb ustib le, or e xpl osive atmosph ere.
Select a mounting location on the inside of any building. The console must be protected from severe vibration, extremes
in temperature and humidity, rain, and other conditions that could harm computerized electronic equipment.
The equipment is designed to operate safely under the following range of conditions:
•
Temperature range 0 to 40°C - (storage temperature range of -40 to +74°C).
5
Site Considerations Selecting a Console Location
• A maximum relative humidity of 95% RH (non-condensing) at temperatures up to 40°C.
• Console may be powered by either 120 or 240 Vac. A switch-mode power supply automatically detects the input
voltage (no jumpers required).
• Main supply voltage fluctuations not exceeding ±10%.
• Pollution Degree Category 2.
• Installation Category II.
Consoles must be installed within the interior of buildings. They are not suitable for any external location.
Ensure that the console is located where neither the console nor its associated cabling will be damaged by doors,
furniture, barrows, etc. Consider the ease of routing wiring, ducting, and probe cables to the console. Check that the
mounting surface material is strong enough to support the console’s weight of about 4 pounds.
If the unit requires cleaning, do not use any liquids, wipe only with a clean, dry cloth.

Console Installation
Mounting the Console
Figure 2 illustrates recommended console mounting. Install the console fastening devices to the mounting surface using
the hole pattern (6.7” x 5.7”) shown in Figure 3. Mounting screws up to 3/16” diameter may be used.
Install metal conduit (1/2” I.P.S.) between the console and the power panel. Figure 3 shows the three designated
knockouts (one each on top, left side, and bottom) through which power wiring can safely enter the console.

Attaching Probe Canister Spacer Rings
1. Open the probe shipping carton so that you have access to the probe. Also open the installation kit.
2. After setting the spacer vanes for a 3- or 4-inch riser (see Figure 5), install the two spacer rings as shown. Note: you
must slide the bottom spacer over the probe and onto the lower end of the canister. NOTE: spacers are not required
for a 2-inch riser.
Assembling Floats onto Probe Shaft
The Product floats, Water Floats (if ordered), and Boots from Probe Installation Kits are assembled on the probe shafts in
the exact
IMPORTANT! Failure to push the boot as far as possible onto the probe shaft could cause the boot and float(s) to fall
into the tank. The boot must be pushed on until it “locks” on the probe shaft. Also, water floats must be installed, if
ordered, for the probe to operate correctly.
Handle the probe carefully. Striking or dropping the probe will result in loss of calibration and could cause permanent
damage.
