Safety Warnings <br /> Circuitry within the sensor and console barrier form an intrinsically safe,energy limited syste►n.This system makes the <br /> sensor intrinsically safe for use in a Class 1,Group D hazardous location.The sensor wiring is intrinsically safe only <br /> when connected to TLS-350 Series Consoles. <br /> This device is installed in equipment where potentially lethal voltages may <br /> exist.This device attaches to accessory components which operate in areas <br /> ® •° where flammable liquids and vapors may be present. <br /> ult Serious injury or death from shock,explosion,or fire may result if power is on <br /> during installation and the device is improperly installed. <br /> When installing this product: <br /> 1. Read and understand all instructions. <br /> 2. Turn off,tag,and lockout power to the console and submersible pumps <br /> while installing the PLLD system. <br /> 3. Do not allow PLLD pump control wires to share conduit with wires from <br /> intrinsically safe devices such as probes and sensors. <br /> 4. Insure that any assembled conduit only enters the console through the <br /> properly designated knockouts. <br /> 5. Wiring must comply with all applicable requirements of the National <br /> Electrical Code;federal,state,and local codes;and any other safety <br /> codes. <br /> 6. Substitution of components may impair intrinsic safety. <br /> Field Wiring Requirements <br /> NATIONAL ELECTRICAL CODE COMPLIANCE <br /> The following information is for general reference and is not intended to replace recommended National Electric Code <br /> (NEC)procedures.It is important for the installer to understand that electrical equipment and wiring located in Class I, <br /> Division I and 2 installations shall comply with the latest appropriate Articles found in the National Electric Code <br /> (NFPA 70)and the Automotive and Marine Service Station Code(NFPA 30A). <br /> PLLD TRANSDUCER-TO-CONSOLE WIRING <br /> Preferred Wiring Type <br /> #14-#18 AWG stranded copper, shielded cable(REQUIRED)and manufactured with a material suitable for the <br /> environment, such as Carol C2534,Belden 88760,or Belden 8760. Wiring to be installed as a Class I circuit with the <br /> following provisions: <br /> • Wire run must not exceed 1000 feet to meet intrinsic safety requirments, <br /> • Capacitance does not exceed 100 pF/ft, <br /> • Inductance does not exceed 0.2 ltH/ft. <br /> 3-1 <br />
