Dispenser Wiring Disconnect"'I Solution <br />The Problem <br />While sites may have an emergency stop <br />button, the emergency stop system that it <br />controls does not meet the current safety <br />requirements defined in4he National <br />Electrical Code® (NEC ). <br />Non compliance with <br />NEC �� 514.11 and 514.13 <br />can create fire, ignition, <br />and safety hazards at <br />petroleum dispensing <br />stations during emergency <br />situations and during <br />maintenance of fueling <br />dispensers. <br />The Solution <br />Power Integrity's Dispenser Wiring DisconnectTM <br />Typical Installation <br />The Dispenser Wiring Disconnects"' has <br />been designed to be installed inline with <br />dispenser data wiring and adjacent to the <br />site controls. <br />The system provides individual service <br />disconnect switches. Each switch <br />disconnects both the corresponding <br />dispenser data and credit card data <br />circuits. <br />When used in conjunction with a Power <br />Integrity AC power system such as the <br />PetroXs?"^ (PXS) or Petro Power <br />SolutionTM (PPS), all equipment <br />requirements for installing the petroleum <br />dispensing system have been addressed <br />making it a simple task for the installer to <br />meet the necessary code requirements. <br />Conductors of the low voltage circuits are not <br />disconnected by the emergency stop operator. <br />The conductors of all circuits including low <br />voltage, intercom and data circuits are to be <br />disconnected simultaneously from the <br />source of supply (514.11) <br />- -= - Emergency <br />3j Intercom Circuits _ Petroleum Stop Opera- <br />s r Power Panel for <br />J <br />Data Circuits <br />ki <br />I <br />t'[ <br />1 <br />Power Circuits Id V J <br />Contactor or <br />/ 1Shunt Trip <br />Breaker <br />A contactor or shunt trip breaker is used to <br />disconnect power to the petroleum panel. <br />These methods do not disconnect dis- <br />penser power circuit conductors from the <br />source of su f . 514.11 <br />Dispenser Wiring DisconnectIm Solution Intercom System <br />disconnects dispenser data wiring for <br />compliance with NEC Article 514 — Dispenser Wiring <br />{ Ell 3ttl DisconnectTm Solution <br />Expansion disconnects <br />--- I dispenser intercom <br />Dispenser Forecourt Site Controls . �� wiring for compliance <br />I with�NEC Article 514 <br />Dk-a -isrn; 1--W i <br />MaX ?
