BT4, and DDS series.
NOTE: Rec mmended f r use n inverter duty rated m t rs. F ll w m t r manufacturer rec mmenda-
ti ns f r cable lengths when using variable frequency drives.
When perating a surface system, drives are c nfigured based n m t r current capacity rather than
h rsep wer. M t r current capacity is pr grammed thr ugh DIP switch settings. Refer t “System Re-
sp nse (DIP SW3)” n page 34.
Model Current Capacity
SubDrive15 2.0 – 5.9 A, 230 VAC three-phase
SubDrive20 2.0 – 8.1 A, 230 VAC three-phase
SubDrive30 2.0 – 10.9 A, 230 VAC three-phase
SubDrive50 2.0– 17.8 A, 230 VAC three-phase
NOTE: Using the FE C nnect M bile App, m t r verl ad current can be set fr m 2.0 A up t the max
current rating f the drive m del in 0.1 A increments. Refer t “Drive C nfigurati n Using the FE C nnect
App” n page 44.
Three-Phase Pump Sizing and Performance
SubDrive C nnect m dels are capable f driving a smaller threep-
hase pump, either standard inducti n r MagF rce permanent
magnet, than the m t r h rsep wer rating t a similar r better
perf rmance than a c nventi nally matched pump and m t r. This
has the effect f extending the perf rmance curve f the verall
system at b th l w and high fl w rates. See the example at right.
T select the pr per pump f r y ur applicati n, first ch se the
c nventi nally matched pump and m t r c mbinati n that meets
the head and fl w requirements. Refer t the Franklin Electric AIM
Manual.
Then, select an appr priate smaller pump fr m the same pump
series (fl w rating) that w rks with y ur SubDrive C nnect m del.
Refer t “Applicati ns” n page 9.
The m t r and pump sizes must be c nfigured using DIP switch
settings n the SubDrive C nnect. Refer t “Submersible M t r
and Pump Sizes (DIP SW2 & DIP SW3)” n page 32.

Minimum Pressure Tank and Supply Pipe Sizing
A VFD system needs nly a small pressure tank t maintain c nstant pressure, alth ugh a larger tank
may be used.
• If adding a drive t a system with an existing large tank, refer t “Tank Size and Bump M de Adjust-
ments (FE C nnect App Only)” n page 35.
• The pressure tank pre-charge setting sh uld be 70% f the targeted system pressure.
