miRO TECHNICAL BULLFEETINT13009 <br /> 4($� Franklin Fueling Systems May 20, 2004 <br /> Mag-VFC Electrical Installation <br /> The Mag-VFC (Variable Frequency Controller for the IST) electrical installation must be performed <br /> in accordance with the Mag-VFC Installation and Owner's Manual and all applicable Federal, <br /> State, and Local regulations. <br /> The Mag-VFC requires 200-250 Volt, 1 or 3 Phase, 50 or 60 Hz input power and a properly <br /> connected ground. The output power to the IST (the pump which includes the manifold and Pump <br /> Motor Assembly) is regulated by the Mag-VFC. The IST has a variable speed, three phase motor <br /> which requires three power wires and a ground wire of the proper size and type for installation in <br /> hazardous locations. Grounding the Mag-VFC and the IST is very important and should be done per <br /> the Federal, State, and Local Regulations as well as per the NFPA and NEC. Each IST requires a <br /> Mag-VFC for operation. <br /> Electrical interference is created by several types of equipment in a station (i.e., compressors, <br /> fluorescent lighting, submerged pumps, etc.), some more than others, and this interference can affect <br /> the operation of more sensitive equipment (such as tank monitors and electronic line leak detectors) <br /> which communicate through data lines. Data communication is highly sensitive in some cases and <br /> the routing of equipment power wires (i.e., compressors, fluorescent lighting, IST, etc.) near, or within <br /> the same conduits, raceways, or power panels as communications lines can cause communication <br /> problems. <br /> When installing the Mag-VFC, FE Petro recommends that the power wires from the Power <br /> Source as well as the power wires to the IST be in their own steel conduit which is not broken or <br /> routed through raceways. If this is not possible, at a minimum, power wires need to be in separate <br /> steel conduits from data communication wires. Please see the table below for the maximum wire <br /> length to wire gauge recommendations for submersible wiring. FE Petro also recommends that all <br /> equipment be installed per the manufacturer's requirements for best results. <br /> Wire Size Maximum Run <br /> 10 Gauge 650 Feet <br /> 12 Gauge 400 Feet <br /> 14 Gauge 250 Feet <br /> Please contact Technical Support 'f we may be of any assistance. <br /> Franklin Fueling Systems - 3760 Marsh Rd. • Madison WI 53718 USA <br /> Tel: +1 608 838 8786 • 800 225 9787 • Fax: +1 608 838 6433 •www.franklinfueling.com <br />
