Electrical Installation
Wiring Guidelines
1. Wire directly to the service entrance. Do not connect to a sub-panel.
2. Use a dedicated branch circuit for the drive.
3. Route motor wiring out of the building as soon as possible. Separate input power and motor wiring by
at least 8 in. (20.3 cm).
4. Cross over other branch circuits and facility wiring at a 90 angle. If it is necessary to run wiring in par-
allel, separate by at least 8 in. (20.3 cm).
5. All control wiring—sensors, switches, transducers, etc.—should be in a separate conduit routed individu-
ally, not parallel, from high voltage wiring. In addition, any shielded cables should be properly grounded.
Branch Circuit Protection
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protec-
tion must be provided in accordance with the National Electrical Code and any additional local codes, or the
equivalent. Drive shall be protected by fast-acting Class T fuses only.
Terminal Block Wire Size
Maximum Torque
Do not use power tools to tighten terminal block screws, use hand tools only. Tighten terminal block screws
to a maximum torque of:
AWG 20 to AWG 6 - 15 in-lbs (1.7 Nm)
AWG 20 to AWG 2 - 31 in-lbs (3.5 Nm)
AWG 16 to AWG 2/0 - 50 in-lbs (5.5 Nm)
Risk of damage to VFD, or malfunction can occur.
Follow all wire routing and grounding instructions carefully. Inductive currents caused by parallel wiring, or close
proximity between high voltage and control wiring can cause unexpected behaviors.
• Do not run input power and motor wires in the same conduit.
• Do not run motor wires from multiple VFDs in common conduit.
• Do not run any wiring through the airflow channel in the back of the drive.
• Do not run control wiring parallel with high voltage wiring.
• Do not install a magnetic contactor or disconnect in the motor circuit.
• Do not run VFD wiring parallel with house or out-building wiring.
• Do not use aluminum wires for VFD connections.
• Do not use with a Ground Fault Circuit Interrupter (GFCI).
• All wiring must comply with the National Electrical Code and local codes.
• Improper splicing or damage to motor cable insulation may expose the conductor(s) to moisture and can pro-
duce motor cable failure.
• For retrofit application, make sure to check the integrity of power and motor leads. This requires measuring the
insulation resistance with a suitable megohm-meter.

Power Wiring Connections
Incoming Power Supply
Before connecting power to drive, test incoming voltages as follows:
•230V Models: The line to line and line to ground voltage must be 190-253V (208-230V ±10%). The line
to ground voltage must be less than or equal to 253 V.
•460V Models: The line to line and line to ground voltage must be 414-506V (460V ±10%). The line to
ground voltage must be less than or equal to 506 V.
If line to line voltage exceeds these ratings, the drive cannot be used on the incoming power supply. An
additional suitably sized transformer will be required to bring the voltages within limits.
IMPORTANT: If line to ground voltage exceeds these ratings, remove Power Board EMC jumpers from J10
and J11 (four total). This is common in applications supplied by a Corner-Grounded Delta transformer. Refer
to the NOTICE above.
1. Incoming Power terminal block.
2. Power Out to Motor terminal block. If the drive is equipped with a dV/dt
(EMI) filter, this terminal block is pre-wired to the dV/dt filter. The motor
is wired to the terminal block on the dV/dt filter.
3. J10 Jumper location (two jumpers here).
4. J11 Jumper location (two jumpers here).
Ground Connections
1. Make sure a service entrance ground rod is properly installed and connected.
2. An input power ground wire from the supply panel must be connected to the drive.
3. A dedicated output ground wire from the drive must be connected to the motor. Motor and ground
wires must be bundled together.
Contact with hazardous voltage could result in death or serious injury.
• Disconnect and lock out all power before installing or servicing equipment.
• Connect the motor, the drive, metal plumbing, and all other metal near the motor or cable to the
power supply ground terminal using wire no smaller than motor cable wires.
• Close any open conduit holes before finishing installation.
Risk of damage to drive, or malfunction can occur.
• Power source line to line, and line to ground voltages must be measured before connecting the
drive. If line to ground voltage exceeds specification, both pins of EMC jumper J10 must be removed
to prevent damage to the drive. Refer to “Incoming Power Supply” below.
• Ensure that the system is properly grounded all the way to the service entrance panel. Improper
grounding may result in loss of voltage surge protection and interference filtering.

Drive Configuration
To adjust system settings, make sure power is off for five minutes, and remove the cover. Then, power the drive to make menu and
DIP switch changes. When changes are complete, power off the drive before replacing the cover.
DIP Switch Settings
DIP switch changes can be made with the drive powered and
will take effect immediately.
Basic Setup (DIP SW1 – Position 1)
DIP SW1 Position 1 (FE Connect mobile app switch) must be in
the OFF (down) position for DIP switch settings to be recognized. If the switch is in the ON (up) position, the drive can be pro-
grammed using the SubDrive Connect Plus mobile app. This setting disables DIP switch control and app programming overrides
any manual DIP switch settings. Refer to “FE Connect Mobile App for SubDrive Connect Plus” on page 10 for more information.
NOTE: The menu-based settings can be changed regardless of the position of this DIP switch.
Carrier Frequency Switch (DIP SW1 – Position 2)
In CEN applications where audible electrical noise can be heard from the motor, increasing the carrier frequency (CF) can help
reduce or eliminate audible electrical noise.
• Carrier frequency setting is 2.5 kHz when the switch is in the off (down) position.
• Carrier frequency setting is 8 kHz when the switch is in the on (up) position.
NOTE: SUB drive models (filtered drives) do not allow 8 kHz.
Pipe Fill Switch (DIP SW1 – Position 3)
When enabled, the Pipe Fill (PF) feature will run the motor at reduced speed while the pipes fill with water. This can reduce water
hammer in some systems, building up pressure in a controlled manner.
• The Pipe Fill feature is disabled when the switch is in the off (down) position.
• The Pipe Fill feature is enabled when the switch is in the on (up) position.
NOTE: Additional configuration of the Pipe Fill feature is available in the SubDrive Connect Plus mobile app.
Analog Output Selection (DIP SW1 – Position 4)
Use this switch (AO) to select the signal to be repeated on the 4-20mA Output terminal.
• The analog output is proportional to the motor speed value when the switch is in the off (down) position.
• The analog output repeats the 4-20mA transducer reading when the switch is in the on (up) position.
Bump Mode Configuration (DIP SW1 – Position 5)
Bump mode controls how hard the drive will pump just before stopping the motor when the pressure setpoint is reached. For
applications with a large pressure tank, or if the system takes too long to stop, place the switch in the ON (up) position for a more
aggressive bump.
• Test system behavior to ensure proper operation.
NOTE: Additional configuration of the Bump Mode feature is available in the SubDrive Connect Plus mobile app.
Broken Pipe Protection (DIP SW1 – Position 6)
When enabled (in Auto mode only), this feature stops the system and displays a Fault condition if the drive runs at full speed for 10
minutes without reaching the pressure setpoint.
If the system is used with a sprinkler system or is being used to fill a pool or cistern, the feature should be disabled.
• The Broken Pipe fault is disabled when the switch is in the off (down) position.
• The Broken Pipe fault is enabled when the switch is in the on (up) position.
NOTE: Additional configuration of the Broken Pipe feature is available in the SubDrive Connect Plus mobile app.

Menu Settings
To adjust system settings, make sure power is off, and remove the
cover. Then, power the drive to make menu changes. When changes
are complete, power off the drive before replacing the cover.
Use the arrow keys to the right of the Display to navigate through the
setup menus.
• The right arrow moves from screen to screen, and also functions
as an Enter key.
• The up and down arrows scroll through the available options on
each screen.
• When a selection has been made, you must press the Enter key
(right arrow) for the setting to take effect.
NOTE: If DIP SW1 – Position 1 is ON, settings can be made either through the manual display, or through the mobile app. Changes in
either tool are reflected in the other. Power cycling the drive is not required for menu based or DIP switch settings to take effect.
Menu Navigation
Home Screen: In normal operation, this screen displays the current system status. During setup, pressing the Enter key (right
arrow) changes the display to the Motor Type screen.
Motor Type: Configures the drive for the type of motor being used. Selecting SUB configures the drive for use with a submersible
motor. Selecting CEN configures the drive for an above-ground, centrifugal motor.
NOTE: SUB drive models can be configured for either type. CEN drive models can only be configured for CEN pump/motor type.
Max Amps: The Max Amps value is used to configure various protection features (pump underload, motor overload, etc.). This
value should match the Service Factor Amps or Maximum Amps rating listed on the motor nameplate.
Sensor Type: Configures the drive for the type of pressure transducer or sensor being used. Selecting Transducer displays the Sensor
Range screen. If a standard Pressure Sensor is selected, the target pressure is set using the adjusting screw on the sensor itself. The Sys-
tem Response screen is displayed next for Pressure Sensor use.
Sensor Range: This is only configurable when the sensor type is transducer. This setting scales system operation to the installed
transducer. The range is 100 to 300, with a default setting of 200 PSI. When changing, the setting changes in 10 PSI increments.
Setpoints: Drive speed control is based on the difference between the setpoint and the transducer feedback value. As user
demand (flow) causes pressure changes, the drive varies the output frequency (motor speed) to maintain pressure at or near the
target setpoint. There are two user configurable setpoints in the system—Setpoint 1 and Setpoint 2. If an application has different
pressure requirements for specific uses, the dual setpoint feature can be used by connecting a switch to the Dual Setpoint terminal
block on the control board. Refer to “Control Circuit Connections” on page 5. When the dual setpoint input is open, Setpoint 1 is
used for pressure control. When the input is closed, Setpoint 2 is used.
•Setpoint 1: When using a Pressure Transducer, use this screen to set the desired target pressure the system will maintain
during normal operation. Recommended maximum value is 5% less than sensor max for proper operation.
•Setpoint 2: Set an alternate setpoint here.
NOTE: Factory defaults for the Setpoints are 0 PSI. This puts the drive in the Sleep/Stop state, keeping the drive from running while
programming takes place. The Drive will run 5 seconds after SETPOINT 1 is adjusted above 0 PSI and NEXT button is pressed.
IMPORTANT: Monitor pressure gauge during initial startup to ensure system does not over-pressurize.

Drawdown: When using a pressure transducer, a pressure offset can be set to allow for more water to be drawn from the pressure
tank before a sleeping drive will start. This will reduce sleep/wakeup cycles.
For example, a system setpoint pressure of 50 PSI and a drawdown value of 20 PSI would cause the drive to maintain system pres-
sure at 50 PSI when running; however when the system is idle, the drive will not start the motor until the system pressure drops
below 30 PSI.
System Response: System response time affects how the drive reacts to the pressure transducer/sensor feedback. Faster response
times can improve pressure stability in some systems. However, if the response is too fast, the system could overshoot, leading to
overpressure, rapid cycling, or hydraulic noise. Selections include SLOW, MEDIUM, FAST, and Custom. These control the following
configuration items:
• Proportional Gain, default = 500
• Integral Time, default = 25 (2.5 seconds)
• Ramp Time, default = 10 (1.0 seconds)
• Acceleration Time, default = 2s for SUB, 20s for CEN
• Deceleration Time, default = 2s for SUB, 20s for CEN
Underload Sensitivity: The drive is configured to ensure detection of Underload faults in a wide variety of pumping applications. In
rare cases (as with certain pumps in shallow wells), this trip level may result in unnecessary faults. If the pump is installed in a shal-
low well, activate the drive and observe system behavior. Once the system begins to regulate pressure, check operation at several
flow rates to make sure the default sensitivity does not cause false Underload trips.
•Shallow Set: If the pump is installed in an extremely shallow well and the system continues to trip, then adjust to a lower sen-
sitivity setting. Check the Underload trip level and repeat as necessary.
•Deep Set: In cases where the pump is set very deep, run the system at open discharge to pump the well down and observe
carefully that an Underload is detected properly. If the system does not trip as it should, adjust to a higher sensitivity setting.
Underload Off Time: This setting determines how long the drive will wait before attempting to run after an Underload event. The
default is Smart Reset, but is user-adjustable from 5 minutes to 24 hours.
• Smart reset will set the underload off time to 5 minutes for the first fault. If the drive faults again immediately following the 5
minute off time, the next off time is doubled.
QR Code: This screen displays a code identifying the drive for connection to the mobile app. This screen also displays the software
version and the drive/motor voltage.
Fault Codes: While the QR code is displayed, pressing the DOWN button causes the display to scroll through the last five fault
codes beginning with the most recent one. The display shows the Fault Log Number (1-5), Fault Code, Fault Description, Date/Time
(shown as mm/dd/yy hh:mm:ss).
Special Functions
Reset to Factory Settings: From the HOME screen, press and hold the UP/DOWN/NEXT buttons at the same time for 3 seconds. A con-
firmation screen (Are you sure?) appears in the display. Choosing YES restores all programmable parameters to factory default set-
tings (fault history is NOT cleared). Choosing NO reverts back to the HOME SCREEN.
MANUAL STOP Mode: From the HOME screen, press and hold UP/DOWN buttons together for 2 seconds to manually place the
drive in STOP mode. The display shows STOP in the upper right corner of the HOME screen where RUN/STOP status is shown (same
as placing a jumper on the RUN/STOP input terminal).
When activated, MANUAL STOP displays centered at bottom of HOME screen where the motor speed (HZ) and output current (A)
readouts were displayed.
Pressing the UP/DOWN buttons again for 2 seconds removes the drive from manual stop mode.

Operation
Hand/Auto Mode
When powered up, the drive reads the signal on Control Board J10 (Hand/Auto). If a Hand/Auto switch is not
used, the absence of a connection here appears as an open switch, and puts the drive in Auto mode. When a
Hand/Auto switch is used, an open switch puts the drive in Auto mode. In Auto mode, the drive controls the
pump to maintain a constant pressure.
If a Hand/Auto switch is connected to Control Board J10 (Hand/Auto), closing the switch puts the drive in
Hand mode. Hand mode runs the pump at a constant speed (default is 60 Hz, shown in the display). Hand
mode allows the drive to be run at full speed without a pressure transducer for longer periods of time as in
the case of new well development or system start up. Moving the switch back to Auto mode resumes the
automatic pressure tracking and control by the VFD.
System Status
When the drive is controlling the motor and pump, the display is illuminated
and the following information is shown:
1. Whether the system is in HAND or AUTO mode.
2. Whether the motor is running (RUN) or stopped (STOP).
3. When using a pressure transducer, the system displays the current sys-
tem pressure in PSI.
When using a standard pressure sensor, the system displays the current motor speed (in Hz).
When running in HAND mode, the system displays the keypad frequency setpoint.
4. When using a pressure transducer in AUTO mode, the motor speed is displayed at the lower left of the
screen. In HAND mode, current system pressure is displayed.
When using a standard pressure sensor, this field is not displayed.
5. The lower right of the screen displays output current in Amps.
6. The Bluetooth icon indicates that the VFD is connected to a mobile device running the FE Connect -
SubDrive Connect Plus mobile app. A thermometer icon displayed at the left side of the screen indi-
cates the drive is in Over Temperature Foldback
Fault Detected
If a fault condition occurs, the drive displays the Fault Code and Fault Description.
Several faults reset automatically, displaying a countdown timer until the reset occurs.
Pressing the DOWN button while the countdown timer is active resets the fault immedi-
ately. For faults that require a manual reset, turn off power to the drive (power cycle) and
restart after five minutes.
Refer to “Diagnostic Fault Codes” on page 11 for details.
