Introduction
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 Code for Motor Fuel Dispensing Facilities and Repair Garages (NFPA 30A), or
other local code such as the CEC, Canadian Electrical Code.
TLS RF-TO-TLS CONSOLE WIRING
Wire Type
To ensure the best operating systems available, Veeder-Root REQUIRES the use of shielded cable.
Wire Length
Improper system operation could result in undetected potential environmental and health hazards if the TLS RF-to-
TLS Console wire runs exceed 1000 feet. Wire runs must be less than 1000 feet to meet intrinsic safety
requirements.
Splices
Veeder-Root recommends that a minimum number of splices are used in the wire run between the TLS RF and the
TLS 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. TLS RF-to-TLS Console wires must be #14 to #18 AWG
stranded copper wire and installed as a Class 1 circuit.
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 µH/foot
TLS RF AC POWER WIRING
Wires carrying 120 or 240 Vac from the power panel to the TLS RF must be at least#14 AWG copper wire for
line, neutral and chassis ground (3); and #12 AWG copper wire for barrier ground (1).
NOTE: Note: See page 30 for details of Repeater Power Wiring.
ELECTRICITY
High voltage exists in, and is supplied to, the
device. A potential shock hazard exists.
TURN POWER OFF
Live power to a device creates a potential shock
hazard. Turn Off power to the device and associ-
ated accessories when servicing the unit.
WARNING
Heed the adjacent instructions to avoid dam-
age to equipment, property, environment or
personal injury.
READ ALL RELATED MANUALS
Knowledge of all related procedures before you
begin work is important. Read and understand all
manuals thoroughly. If you do not understand a
procedure, ask someone who does.
