Installation Instructions <br />Note: Steps 1 through 3 are also part of the installation <br />instructions for the submersible pump. This is done <br />to make sure all instructions are available if needed <br />during installation. As a result, steps 1-4 may <br />already be complete. <br />1. Connect the electrical conduit with approved <br />fittings to the submersible pump junction box. <br />2. Remove the submersible pump junction box cover, <br />and remove the compression seal by loosening <br />the screw (do not remove the screw). The seal <br />has four holes to accommodate a ground wire and <br />three-phase power from the MagVFC. <br />Not installing a ground wire increases <br />Warning the risk of potentially lethal electrical <br />shock and equipment failure. All holes <br />of the compression seal (contractors <br />plug) must be filled with wires or a <br />Celcon rod to enable it to seal. <br />3. Verify that the power is OFF at the supply box. <br />Pull four wires from the spot where the MagVFC <br />unit will be mounted into the submersible pump <br />junction box and feed through the compression <br />seal. Slide the compression seal into place and <br />tighten securely. Connect the three wires from <br />the connector assembly to the three phase power <br />wires coming from the MagVFC. Connect the <br />fourth wire (ground) from inside to the pump <br />junction box ground lug. <br />Note: All wiring must conform to all applicable guidelines <br />in accordance with all federal, state, and local <br />codes. Failure to comply with all applicable <br />guidelines could result in an unsafe installation. Use <br />the following table for maximum wire length to wire <br />gauge for submersible wiring: <br />14 gauge <br />650 feet <br />12 gauge <br />400 feet <br />14 gauge <br />250 feet <br />4. Replace the cover of the pump junction box and <br />securely tighten in place. <br />Warning The compression seal is not a <br />replacement for the vapor explosion <br />seals required by the NEC. All materials <br />used between the power supply box <br />and the submersible pump junction box <br />must be gasoline and oil resistant. All <br />wiring used within the MagVFC must <br />be rated 90°C, 300V minimum. Failure <br />to comply with these, and all applicable <br />NEC guidelines, could result in an <br />unsafe installation. <br />0 <br />5. Hang the MagVFC on a vertical surface and <br />remove the front panel screw and front cover. <br />Install approved electrical conduits only at factory <br />knockouts on the MagVFC enclosure. <br />Note: Interference is created by several types of <br />equipment in a station (fluorescent lighting, <br />compressor, etc.), some more than others; this <br />interference can affect the operation of more <br />sensitive equipment (such as tank monitors and <br />electronic line leak detectors) which communicate <br />through data lines. When installing the MagVFC, <br />FE Petro recommends that the power wires from <br />the Power Source as well as the power wires <br />to the IST or STP units with VS2 or V34 suffix <br />(pump) be in their own steel conduit which is not <br />broken or routed through race ways. FE Petro also <br />recommends that all equipment be installed per the <br />manufacturer requirements for best results. <br />Note: The MagVFC must be mounted indoors in a non- <br />hazardous location with ambient temperatures <br />between 40° F (4° C) and 95° F (35° C). <br />The MagVFC measures 14.25"H x 5.50"W x 9.50"D <br />(Figure 3). <br />Note: To allow room for field adjustments and air <br />clearance, mount the controllers so they have 6" or <br />more of right side (cover side) clearance, and 3" or <br />more left side (heat sink side) clearance. Install with <br />the heat sink fns vertical and the knock -outs down. <br />Figure 3: MagVFC Dimensions <br />5 <br />
