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 Code for Motor Fuel Dispensing Facilities and Repair Garages (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, or 8770.
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
AC POWER WIRING
Wires carrying 120 or 240 Vac from the power panel to the console should be #14 AWG (or larger) wire for line,
neutral and chassis ground (3); and 4 sq. mm, rated for at least 90°C, for barrier ground.
DC POWER WIRING
Wires carrying +24 and +5 Vdc from the DC power source to the console should be #14 AWG wire. For barrier
ground, 4 sq. mm wire, rated for at least 90°C.

The RS-232 D-connector is a panel mount, 9-pin female type, wired in a Data Terminal Equipment (DTE) configura-
tion. For example, any RS-232 port in any TLS consoles is also a DTE, therefore, a Null Cable is needed in order for
communication to happen between the two consoles.
A Data Communication Equipment (DCE) device such as a modem may be connected directly to the interface using
a straight-through cable (modem support may not be available on all ATGs). Handshake signals in the system are
configurable.

Console Installation
Console Location
For console location, refer to the ‘System Consoles’ section of manual 577013-578 on the Veeder-Root Tech Docs
CD-ROM prior to installing the 8601 Series Console.
Mounting the Console
To mount the console remove the two T15 screws in the bottom of the cover (see Figure 1). As you lift up the
bottom of the cover it pivots on two tabs that project from the top of the console’s chassis into slots in the top of
the cover. Lift the cover off the chassis tabs and set it aside. Notice the corner mounting holes in the base of the
chassis (Item 12 in Figure 2). Locate the chassis on the wall in the desired mounting location, mark the hole
locations, drill the appropriate pilot holes; and using 1/4-inch (6mm) maximum fasteners (customer supplied),
attach the chassis to the mounting surface at all four locations.
Figure 1 shows the two designated knockouts through which power wiring can safely enter the console.
Wiring the Console
The 8601 Series Console can be operated using either AC or DC power.
WARNING
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).
WARNING
This console contains high voltages which can be lethal. It is also connected to low
power devices that must be kept intrinsically safe.
1. Turn power off at the circuit breaker. 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

AC INPUT POWER
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 four wires between the power panel and the console; three #14 AWG or larger color-coded wires for AC
line (hot), AC neutral and chassis ground; and one 4 sq. mm wire, rated for at least 90°C, for barrier ground.
3. Connect the input 120 or 240 Vac power wires as shown in Figure 5.

Probe and Sensor Conduit Installation
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 3 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 7].
Pull two or three conductors shielded cable (as required). Individual wires should be color-coded between the
console and the junction box at each 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.
WARNING
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY
PRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT, RESULTING
IN SERIOUS INJURY OR DEATH.
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.

Probe and Sensor Conduit Installation Wiring Run Methods
15
Figure 7. Example Probe Wiring Run in Buried Rigid Conduit
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 by the authority having jurisdiction 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 8].
If you decide upon the direct burial method, consult the direct burial cable installation manual for detailed
installation instructions (reference manual 576013-858).
