Introduction National Electrical Code Compliance <br /> Wire Length <br /> Improper system operation could result in undetected potential environmental and health hazards if the TLS RF-to- <br /> TLS Console wire runs exceed 1000 feet. Wire runs must be less than 1000 feet to meet intrinsic safety <br /> requirements. <br /> Splices <br /> Veeder-Root recommends that a minimum number of splices are used in the wire run between the TLS RF and the <br /> TLS Console. Each splice degrades signal strength and could result in poor system performance. <br /> Wire Gauges- Color coded <br /> Shielded cable must be used in all installations.TLS RF-to-TLS Console wires must be #14 to#18 AWG <br /> stranded copper wire and installed as a Class 1 circuit. <br /> Alternate Method <br /> When approved by the local authority having jurisdiction, 22 AWG wire such as Belden 88761 may be suitable in <br /> installations with the following provisions: <br /> Wire run is less than 750 feet <br /> Capacitance does not exceed 100 pF/foot <br /> Inductance does not exceed 0.2 pH/foot <br /> TLS RF AC POWER WIRING <br /> Wires carrying 120 or 240 Vac from the power panel to the TLS RF must be at least#14 AWG copper wire for <br /> line, neutral and chassis ground (3); and #12 AWG copper wire for barrier ground (1). <br /> NOTE: Note: See page 32 for details of Repeater Power Wiring. <br /> 10-7 <br /> CARO Approved IOM 10-Veeder Root TLS RF Wireless Systems(W2)-Executive Order VR-202 <br />
