PRODUCT INFORMATION
Three-Phase Pump Sizing and Performance
SubDrive Connect Models with Surface Motor Capacity Ratings
SubDrive Connect models will operate many Franklin Electric surface mounted pumps, including VR, MH,
BT4, and DDS series.
NOTE: Recommended for use on inverter duty rated motors. Follow motor manufacturer recommenda-
tions for cable lengths when using variable frequency drives.
When operating a surface system, drives are configured based on motor current capacity rather than
horsepower. Motor current capacity is programmed through DIP switch settings. Refer to
sponse (DIP SW3)" on page

NOTE: Using the FE Connect Mobile App, motor overload current can be set from 2.0 A up to the max
current rating of the drive model in 0.1 A increments. Refer to
Three-Phase Pump Sizing and Performance
SubDrive Connect models are capable of driving a smaller threep-
hase pump, either standard induction or MagForce permanent
magnet, than the motor horsepower rating to a similar or better
performance than a conventionally matched pump and motor. This
has the effect of extending the performance curve of the overall
system at both low and high flow rates. See the example at right.
To select the proper pump for your application, first choose the
conventionally matched pump and motor combination that meets
the head and flow requirements. Refer to the Franklin Electric AIM
Manual.
Then, select an appropriate smaller pump from the same pump
series (flow rating) that works with your SubDrive Connect model.
Refer to "Applications" on page
The motor and pump sizes must be configured using DIP switch
settings on the SubDrive Connect. Refer to
and Pump Sizes (DIP SW2 & DIP SW3)" on page
Generator Sizing
Basic generator sizing for the SubDrive Connect system is 1.5 times the maximum input watts consumed
by the drive, rounded up to the next normal-sized generator.
Model Recommended Generator Watts
SubDrive 15
SubDrive 20
SubDrive 30
SubDrive 50
IMPORTANT: Do not use with a Ground Fault Circuit Interrupter (GFCI). If using an externally regulated
generator, verify that the voltage, hertz, and idle speed are appropriate to supply the drive.
