IntroductionNational 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), the Automotive and Marine Service Station Code (NFPA 30A), CEC codes and all
applicable local codes.
PROBE- AND SENSOR-TO-CONSOLE WIRING
Wire Type
To ensure the best operating systems available, Veeder-Root REQUIRES the use of shielded cable for all probes
and sensors 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™
C2534 or Belden™ 88760, 8760, 8770 or similar.
Note: Throughout this manual, when mentioning any cable or wire being used for probe and sensor 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- or
sensor-to-console wire runs exceed 1000 feet. Wire runs must be less than 1000 feet to meet intrinsic safety
requirements.
Wire Gauges - Color coded
Shielded cable must be used in all installations. Sensor-to-console wires should be #14-#18 AWG stranded
copper wire and installed as Class 2 circuits. As an alternate method when approved by the local authority having
jurisdiction, #22 AWG wire 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 0.2 H/foot
POWER WIRING
Wires carrying 120 or 240 Vac from the power panel to the console should be #14 AWG (or larger) copper wire
for line, neutral and chassis ground (3); and #12 AWG copper wire for barrier ground.

FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY
PRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT,
RESULTING IN SERIOUS INJURY OR DEATH.
Explosive vapors or flammable liquids could be present near locations where
fuels are stored or being dispensed.
This console is not explosion proof. Do not install this console in a volatile,
combustible, or explosive atmosphere.
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).
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 console’s operating temperature range is 32 to 104°F (0 to 40°C), and its storage temperature
range is -40 to +162°F (-40 to +74°C).
The mounting surface should be strong enough to support the console’s weight which could be approximately 35
pounds with a full complement of modules. You should also consider wall space for routing the power wiring
conduits and probe and sensor wiring conduits that must be connected to the console.
Mounting the Console
Install the console fastening devices to the mounting surface using the hole pattern shown in Figure 1. Up to 1/4”
diameter screws may be used.
Mount the console to the mounting surface using the four mounting flanges on the back of the unit. Install metal
conduit between the console and the power panel. Figure 1 shows the two designated knockouts through which
power wiring can safely enter the console.

Wiring the Console
WARNI NG
This console contains high voltages which can be lethal. It is also connected
to low power devices that must be kept intrinsically safe.
1. Do not connect the console AC power supply wires at the breaker until
all devices are installed.
2. Attach conduit from the power panel to the console's Power Area
knockouts only.
Connecting power wires to a live circuit can cause electrical shock that may
result in serious injury or death.
Routing conduit for power wires into the intrinsically safe compartment can
result in fire or explosion resulting in serious injury or death.
1. Check the Input Power Rating on the label affixed to the underside of the console to verify whether input
power requirements are 120 Vac or 240 Vac.
2. Pull three #14 AWG or larger color-coded wires for AC line (hot), AC neutral and chassis ground between the
power panel and the console.
3. Pull one wire, with a minimum 90°C rating, for barrier ground - For UL/cUL installations use a # 12 AWG wire;
For ATEX/IECEx installations use a 4 mm
4. Connect the input 120 or 240 Vac power wires as shown in Figure 2.

2. If you are installing the metal cap and adapter ring (see Figure 7 on page 10), screw the ring onto the 4” riser
until the gasket contacts the pipe, then use a pipe wrench to tighten it an additional 3/4 turn. Push the cable
through the metal cap and cord grip, then clamp the cap onto the ring.
At sites that require installation of a riser adapter (Phil-Tite M/F 4X4 or equivalent) at the top of the riser, do so
following the manufacturer’s instructions. Next screw the adapter ring from the Veeder-Root kit (
952) onto the riser adapter by hand until the gasket contacts the sealing surface. Then use a torque wrench attached to an appropriate strap wrench (K-D Specialty tools nylon strap oil filter wrench, or equivalent) and tighten the ring to 35 - 45 ft-lbs. Loosen the cord grip nut and push the cable through the metal cap and cord grip,
then clamp the cap onto the ring (see Figure 11).
3. Make sure there is a minimal amount of slack between the probe and cap, then tighten the cord grip nut until
the cable is held firmly. Push the end of the cable through the field J-box cord grip, then tighten that cord grip
nut as well. Splice and seal the wires in the J-box.
AST RISER CAP ATTACHMENT
1. If you are using the one piece cap (see Figure 6 on page 9), push the end of the probe cable through the cap
and cord grip bushing, leaving a minimal amount of slack between the probe and cap. Discard the cord grip
nut and attach the adapter Nut from the AST kit to the cap (see Figure 3 on page 6). Tighten the adapter Nut
until the cable is held firmly. Go to Step 3.
2. If you are installing the metal cap and ring (see Figure 7 on page 10), screw the ring onto the 4” riser until the
gasket contacts the pipe, then use a pipe wrench to tighten it an additional 3/4 turn. Using UL-classified pipe
sealant (suitable for the fuels involved), screw the cord grip fitting into the tapped hole and tighten. Place the
cord grip bushing in the fitting. Discard the cord grip nut and loosely screw the adapter Nut from the AST kit
onto the cord grip fitting (see Figure 3 on page 6). Push the cable through the metal cap, bushing, and
adapter nut, then clamp the cap onto the ring. Make sure there is a minimal amount of slack between the
probe and cap, then tighten the adapter Nut until the cable is held firmly.
3. Next assemble the liquidtight connectors on both ends of the flexible conduit as shown in Figure 3. Push the
cable through the flexible conduit assembly and into the J-box. Connect the flexible conduit assembly to the
adapter Nut on one end and the J-box on the other.
4. Tighten the fittings until snug. Splice and seal the wires in the J-box.
This type installation is usually a retrofit and is usually connected to the console via direct burial cabling. The site
should already be prepped (all digging, saw cutting, and jackhammering done) prior to probe installation (see
Figure 12). A piece of flex conduit should be in place as shown to protect the cable.
Figure 12. Vapor Extractor Cabling Entry
1. Remove any existing hardware from the Vapor Extractor Riser so that it’s 4” NPT riser threads are exposed.
2. Use the extractor wrench tool (OPW Part Number: 89-0044) to remove the Ball Float Check Valve and
Extractor Cage inside the bottom of the 4” riser. Important! - Ball Float Check Valve and Extractor Cage may
be difficult to remove; use caution.
3. Remove any sludge from the bottom of the tank.
4. Assemble the probe floats, spacer rings, and cable as per the Mag Probe Assembly Manual.
5. Gently slide the float(s) to the bottom of the probe shaft. Important! - Handle probes carefully. Striking or
dropping the probe will result in loss of calibration and could cause permanent damage.
6. Carefully lower the probe into the riser pipe until the boot rests on the bottom of the tank.
7.Thread the probe cable through the bottom of the new Coupling adapter and out the tapped opening in its
side.
8. Screw the Coupling Adapter onto the 4” riser until the gasket first contacts the riser pipe. Then use a pipe
wrench to tighten the Coupling Adapter an additional 3/4 turn.
9. Test pull the cable to insure that it is free of spring and that the probe is resting on the bottom of the tank.
(Make sure there is some slack in the cable.)
10. Slip the PG7 cord grip fitting (o-ring end first) over the cable and screw it into the tapped hole in the Coupling
Adapter (ref Figure 4 on page 7 for the correct PG7 cord grip assembly). Tighten snugly - Be careful not to overtighten. Slide the domed nut of the PG7 fitting down the cable and tighten securely onto the PG7 fitting
so that the cable stays firmly in place. Again, be careful not to overtighten.
11. Reattach the riser cap from the original installation onto the Coupling Adapter.
12. Position the Shield-Fitting over the PG7 cord grip and secure with the hose clamp (see Figure 13 on
page 15).
13. Splice the probe cable to the direct burial cable and seal following instructions shipped with the splice kit.
Observe polarity!
14. Secure splice enclosure against the Shield-Fitting with the tie wrap.
WARNING! If Ball Float Check Valve was part of your Overfill Protection System, you now need to
consider another form of overfill protection (i.e. TLS console alarm, drop tube with overfill protection
valve or some other accepted means).
This type installation is usually a retrofit and is usually connected to the console via direct burial cabling. The site
should already be prepped (all digging, saw cutting, and jackhammering done) prior to Probe Installation (see
Figure 12 on page 13). A piece of flex conduit should be in place as shown to protect the cable.
1. Remove any existing hardware from the Vapor Extractor Riser so that it’s 4” NPT riser threads are exposed.
2. Use the extractor wrench tool (OPW Part Number: 89-0044) to remove the Ball Float Check Valve and
Extractor Cage inside the bottom of the 4” riser. Important! - Ball Float Check Valve and Extractor Cage may
be difficult to remove; use caution.
3. Remove any sludge from the bottom of the tank.
4. Assemble the probe floats, spacer rings, and cable as per the Mag Probe Assembly Manual.
5. Gently slide the float(s) to the bottom of the probe shaft. Important! - Handle probes carefully. Striking or
dropping the probe will result in loss of calibration and could cause permanent damage.
6. Carefully lower the probe into the riser pipe until the boot rests on the bottom of the tank.
7.Ensure that the cord grip nut on the new cap is loose so that the bushing can rotate freely.
8. Thread the probe cable through the bushing and nut on the cap, leaving a minimal amount of slack between
the probe and cap.
9. Install the cap onto the riser, threading it by hand until the gasket first contacts the riser pipe. Then lightly tap
the cap with a hammer to tighten it an additional 3/4 turn.
10. Splice the probe cable to the direct burial cable and seal following instructions shipped with the splice kit.
Observe polarity!
11. Bring the cable down the side of riser and secure into place with the tie wrap.
WARNING! If Ball Float Check Valve was part of your Overfill Protection System, you now need to
consider another form of overfill protection (i.e. TLS console alarm, a drop tube with overfill
protection valve or some other accepted means).
Probes and sensors operate in areas where flammable liquids and explosive vapors
may be present.
Improper installation may result in fire or explosion causing serious injury or death.
Practice the following:
1. Read thoroughly and follow the instructions shipped with each probe and sensor.
2. Probe and sensor wiring conduit must not contain any other wires.
3. Probe and sensor wiring and conduits must enter the console only through their
designated areas.
4. Power and communication wires must not enter the intrinsically safe
compartment of the console.
Wiring Run Methods
Two wiring run methods are commonly used for probes and sensors - Wiring pulled through buried, sealed 1/2”
conduit; or direct burial cable. NOTE: PVC conduit is an acceptable alternate where accepted by local codes [ref.
“National Electrical Code Compliance” on page 2 for more detail on cable requirements].
BURIED RIGID CONDUIT
The preferred method, especially in new sites before driveway surfaces are paved, is to pull probe and sensor
wiring through buried 1/2” rigid conduit [Figure 15].
Pull two
console and the junction box at each
or three conductors shielded cable (as required). Individual wires should be color-coded between the
probe and sensor location (do not gang wires together, i.e., splicing all sump
sensor + wires together to run one wire back to console). Use single lengths of wire with no splices to ensure
optimum signal strength.

Probe and Sensor Conduit InstallationWiring Run Methods
CAUTION: Since wires for multiple sensors may enter the console through a single conduit, it is recommended
that you use a different color-code for each wire or individually mark each wire to identify sensor inputs. Also, if the
intrinsically safe wires enter the building in a wiring trough, only Veeder-Root intrinsically safe wire can be in the
trough. Keep all low power (intrinsically safe) wiring isolated from high power wires in all wiring troughs.
DIRECT BURIAL CABLE
An alternative to trenching through existing pavement is to use direct burial cable. Before considering the direct
burial method, check to be sure that direct burial practices are acceptable at this location. The direct burial method
requires grinding using an abrasive wheel, 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, laying an expanded polyethylene foam backer rod over the cable(s), and then a placing a 1/4” to 1/
2” bead of silicone sealant over the backer rod to within a minimum of 3/8” below the pavement surface [see
Figure 16].
If you decide upon the direct burial method, consult the direct burial cable installation manual for detailed
installation instructions (reference manual 576013-858).
