Fill-Rite piggybacks power off the AC input. Your wiring configuration will depend on whether the pump runs on AC or DC power. For use with DC applications a Class 2 power supply is required for the board’s power.
DC
DC input requires ~12V DC. Attached positive power to DC+ output (terminal 3) and ground to DC- (terminal 2) as demonstrated on the graphic to the right (or below).
For output power, attach the load positive load wire to DC+ output (terminal 28) and ground to DC- (terminal 29).
The NXFM150 hardware accepts up to 5 pumps or loads. For each additional pump please connect the input and out power on channel 2 through 5.
AC
AC input requires 80-240V AC. Attach Line power to L/DC+ (terminal 3), Neutral to N/DC- (terminal 2), and Earth Ground to (terminal 1).
For output power, attach the load Line wire to the L/DC+ output (terminal 28) and load Neutral to N/DC- (terminal 29).
RS-485
The NXFM150 and NXFM100 must be connected through RS-485 to communication. Both hardware units have 3 wiring terminals that must be connected to each other. A, B, and GND on the NXFM150 need to be connected to A, B, and GND on the NXFM100.
