SubDrive/MonoDrive Connect
SubDrive30
The SubDrive30 is capable of use with 1.5 hp (1.1 kW) pumps that are mounted to 3.0 hp
(2.2 kW) Franklin Electric three-phase motors. In general, the SubDrive30 will enhance
the performance of a 1.5 hp (1.1 kW) pump to a similar or better performance than a
conventional 3.0 hp (2.2 kW) pump of the same flow rating (pump series).
To select the proper 1.5
hp (1.1 kW) pump, first
choose a 3.0 hp (2.2
kW) curve that meets
the application's head
and flow requirements.
Use the 1.5 hp (1.1 kW)
pump in the same pump
series (flow rating). The
SubDrive30 will adjust
the speed of this pump to
produce the performance
of the 3.0 hp (2.2 kW)
curve. An EXAMPLE of this
is illustrated in the graph
at right. Please consult
the pump manufacturer's
pump curve for your
specific application.
The SubDrive30 can also be set up to run a 2.0 hp (1.5 kW) or 3.0 hp (2.2 kW) pump if
desired, but larger pumps will still produce to the 3.0 hp (2.2 kW) curve and may only be
operated with a 3.0 hp (2.2 kW) motor. To operate a different pump size, a DIP switch must
be positioned to select the correct pump rating. Otherwise, the SubDrive30 may trigger
erroneous faults.
See the Basic Setup section of this manual for DIP switch information and settings.

WARNING
!
Serious or fatal electrical shock may result from contact with internal electrical components.
DO NOT, under any circumstances, attempt to modify DIP switch settings until power has been
removed and 5 minutes have passed for internal voltages to discharge! Power must be removed
for DIP switch setting to take effect.
