New Sites Planning Probe and Sensor Installation <br /> N _ <br /> _ Intrinsically safe wiring shall be installed in <br /> accordance with Article 504-20 of the latest <br /> Double Wall Tank National Electrical Code(NFPA 70). <br /> WARNING: <br /> Substitution of components may impair intrinsic safety. <br /> Circuitry within the TLS-350(R)Console barrier forms <br /> an intrinsically safe,energy-limited system. This <br /> system makes TLS-350(8)probes and sensors safe for <br /> use in a Class I,Group D hazardous location.TLS-350(R) <br /> probe and sensor wiring is intrinsically safe only when connected to Veeder-Root's TLS-350(8)Console Form <br /> - �;-----; Numbers 8470 and 8482. <br /> rdous <br /> -mazo% <br /> 1 - _ <br /> .—PA !S-�'-- <br /> Non-Hazardous 0 <br /> Area <br /> TLS-350 Area 11 <br /> TLS-350R <br /> is CIRCUfT <br /> PS BREAKER <br /> PANEL DS Discriminating Sump Sensor <br /> ' T PA 120 OR 290 VAC DP Dispenser Pan Sensor <br /> PA'4 i <br /> SpA MD HEOrWD INGW Groundwater Sensor <br /> I� sIS Interstitial Liquid Sensor <br /> 3 k EIN PD PUMP <br /> ®COONTTRRO L PA ti-I IN MD MDIM Pulser/Totalizer Input <br /> Box i 1st_ (TLS-350R only) <br /> I �e <br /> M M MP Magnetostrictive Probe <br /> PD Volumetric Line Leak <br /> 1 i - Detection Inputs <br /> 1 i 0------- --_-_e._a PS Pump Sense Input <br /> -----------------_... ._... ... _y E <br /> Single Wall Tank ;__ _ ________ _ t ` ( PS PD OD Pressurized Line Leak <br /> E F S E .-, OD DISPENSER Detection Inputs <br /> MD as Pressurized Line Leak Sensor <br /> T Thermistor Sensor <br /> V Vapor Sensor <br /> ( i WD Wireless Pressurized Line <br /> r _1 Leak Detection Inputs <br /> DISPENSERS <br /> € Expoxy Sealed Connection in <br /> E <br /> a Weatherproof Junction Box <br /> ' Explosionproof Junction Box <br /> t i@ }-m_---- ®Seal-O/f <br /> Terminal Connection <br /> 0 Capped Conduit <br /> 1/2"Rigid Conduit <br /> Single Wall Tank IS Conduit Enters Console in an <br /> Intrinsically Safe Area Knockout <br /> PA Conduit Enters Console in a <br /> Hazardous AreaPower Area Knockout <br /> ---Product piping <br /> f <br /> Consoles\Instdia.eDs <br /> Figure 4.
