Installation Guide National Electrical Code Compliance5National Electrical Code ComplianceThe following information is for general reference and is not intended to replace recommended NationalElectric Code (NEC) procedures. It is important for the installer to understand that electrical equipment andwiring located in Class I, Division 1 and 2 installations shall comply with the latest appropriate articles found inthe 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 UNIT-TO-TLS CONSOLE WIRINGWire TypeTo ensure the best operating systems available, Veeder-Root REQUIRES the use of shielded cable for probeoutputs regardless of conduit material or application. In these installations, shielded cable must be rated lessthan 100 picofarad per foot and be manufactured with a material suitable for the environment, such as Carol™C2534 or Belden™ 88760, 8760, or 8770.Wire LengthImproper system operation could result in undetected potential environmental and health hazards if the TLSRF-to-TLS Console wire runs exceed 1000 feet. Wire runs must be less than 1000 feet to meet intrinsicsafety requirements.SplicesVeeder-Root recommends that no splices be made 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 codedShielded cable must be used in all installations. TLS RF-to-TLS console wires should be #14-#18 AWGstranded copper wire and installed as a Class 1 circuit. As an alternate method when approved by the localauthority having jurisdiction, 22 AWG wire such as Belden 88761 may be suitable in installations with thefollowing provisions:- Wire run is less than 750 feet- Capacitance does not exceed 100 pF/foot- Inductance does not exceed 0.2 μH/footTLS RF POWER WIRINGWires carrying 120 or 240 Vac from the power panel to the TLS RF should be #14 AWG copper wire for line,neutral and chassis ground (3); and #12 AWG copper wire for barrier ground (1).
