Figure 1: EcoVFC Wiring
Hook Terminals: Voltage signal from the dispensers to turn pump on. Requires a signal wire and a neutral.
No polarity requirements at the Hook Terminal.
Pump Motor Terminals: Labeled GND, BLK,ORG, RED. Connect wires that go to the submersible pump at
these terminals. If color codes are not matched at the submersible the motor may
run in reverse.
Input Power Terminals: Labeled GND, L3, L2, L1. Supplies power for EcoVFC and the submersible pump.
EcoVFC accomodates type TT or TN grounding congurations.
Apply power to the controller BEFORE allowing hook signal input. (There should be NO hook
signal present when applying power to the controller).
Note: Connect wires accurately. Connecting power wires to any other terminals will cause irreparable damage
to the EcoVFC controller.
Note: The EcoVFC can only be used with FE Petro Pump base models IST, IST VS4, STP VS4, STP VS2, PMA
VS4, or PMA VS2. The EcoVFC is not compatible with competitive makes of variable speed models. The
EcoVFC is compatible with the IST-VFC for communication in Master / Slave congurations only if the
EcoVFC has software revision 1.18 or higher.
Note: This drive requires circuit breakers rated 360-440 volts, 40 Ampere maximum for branch circuit short
circuit protection.
