0 <br />6. Refer to Figure 1. Connect the three motor control <br />wires from the pump junction box to labeled <br />terminals observing color coding of wires (Black to <br />Black, Orange to Orange, Red to Red). Connect <br />the ground wire from the submersible pump to the <br />ground lug on the MagVFC circuit board. <br />To avoid the risk of potentially lethal <br />Warning <br />A electrical shock, fire, or explosion, <br />always tag and lock circuit breakers <br />in the off position before opening the <br />MagVFC. <br />After disconnecting power to the <br />Warning MagVFC, wait one minute after LED <br />display blanks before opening the <br />cover for servicing. Voltage stored <br />in the capacitor bank of the MagVFC <br />presents a risk of potentially lethal <br />electrical shock even after power is <br />disconnected. <br />Note: If the motor power wires are not connected with the <br />proper polarity, the motor will run in reverse rotation <br />causing output pressures of approximately 17-29 <br />psi with a PMA VS4 and approximately 10-18 psi <br />with a PMA VS2 connected. <br />7. Connect three phase, 200-250V, 50 or 60Hz power <br />supply to terminals to L1, L2 and L3. Reference <br />Figure 1 for wiring details. <br />Note: The MagVFC may be connected to single phase <br />power only if used with FE Petro pump motor <br />model PMA VS2 with input power connected to L1 <br />and L2. Refer to Figure 1 for wiring details. <br />Note: The PMA VS4 model pump motor requires three- <br />phase input voltage for optimum performance. <br />Operating on single phase input, the performance of <br />the PMA VS4 will be equivalent that of the PMA VS2. <br />Do not connect incoming power to <br />Warning any terminals other than L1, L2, and <br />U. Connecting input power to any <br />other terminals will cause failure and <br />permanent damage to the MagVFC. <br />Warning There must be NO hook signal present <br />when applying power to the controller. <br />8. Connect dispenser hook signal to the two position <br />terminal block on the MagVFC board as shown in <br />Figure 1. <br />Note: Dispenser hook terminals are capable of accepting <br />voltages from 110 VAC through 240 VAC <br />dispenser signals. The dispenser hook terminals <br />require a signal wire from the dispenser and a <br />Neutral/Return. <br />I <br />0 <br />Configuration switches are factory set for PMA <br />VS2 in gasoline„ mechanical leak detectors, <br />extended run active, and stand-alone operation <br />as detailed below in Figure 4.
