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 recommendations
for cable lengths when using variable frequency drives.
When operating a surface system, drives are configured based on motor current capacity rather than horse-
power. Motor current capacity is programmed through DIP switch settings. Refer to

NOTE: Using the FE Connect Mobile App, motor overload current can be set from 2.0 A up to the max cur-
rent rating of the drive model in 0.1 A increments. Refer to

Pump Sizing and Performance
SubDrive Connect models are capable of driving a smaller
pump 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 perfor-
mance 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.

"Applications" on page
The motor and pump sizes must be configured using DIP
switch settings on the SubDrive Connect.
