4. Mount the VFD after determining the overall function of the system. Refer to “Physical Installation” on
page 19 for guidelines.
5. Connect the VFD according to the selected motor application and control method(s). Refer to “Electri -
cal Installation” on page 35 for more information.
6. Program the VFD quickly and easily for most standard operations. Refer to “Setting Operating Parame -
ters” on page 48 . Adjust additional parameters for advanced features or options that achieve the
desired performance. Refer to “Advanced Application Options” on page 97 and “Parameter Reference
Tables” on page 201 .
Basic VFD Configuration
The following table includes the most commonly used devices in a motor control branch operated by a VFD.
Adequate peripheral devices and correct connections are essential for proper VFD operation.
AC Power Source Use single- or three-phase power source with voltage within the permissible range of VFD
input power rating.
MCCB, Fuses, or
Franklin Electric
Manual Motor Start -
ers
Select circuit breakers or fuses in accordance with NEC and applicable local codes.
Inline Magnetic
Contactor
Do not use input power contactor for frequent starting and stopping the VFD, otherwise
VFD power components can be damaged.
AC Line Reactor or
Harmonic Filter
A line reactor provides some degree of surge protection and decreases a level of harmonic
distortion in the power line. It is recommended when power source kVA rating is more than
10 times higher than VFD rating.
A Harmonic filter provides a higher level of harmonic mitigation. Integrated DC Chokes are
included in VFD models larger than Frame C, equivalent to a 3% AC line reactor.
EMI/RFI Filter Install an EMI/RFI filter to decrease VFD Electromagnetic and Radio Frequency Interference
with operation of sensitive electronic equipment.
Variable Frequency
Drive
Install VFD with proper orientation, ventilation, spacing etc. according to the requirements
described in this manual with all necessary protective and filtering devices to provide long
and reliable VFD operation.
AC Load Reactor or
Output Filter
(460 V and higher)
Install a load (output) reactor or an output filter to protect motor windings if distance from
VFD to a motor is in the range 45-100 feet. Install output dV/dt filter for a range of 100-
1000 feet (800 feet for submersible pumps), or a sine wave filter for greater distances.
Three Phase AC
Induction Motors or
Permanent Magnet
Motors, including
Franklin Electric
pump motors
The X-Series VFD is not compatible with servomotors.
Opening the motor circuit by disconnect or contactor during VFD run can damage VFD
power components.
