Ac Wiring Connections (Optional); Flow Switch Wiring Connections - Franklin Electric SubDrive Solar Manuel D'installation

AC Wiring Connections (Optional)

The SubDrive Solar controller has AC wiring connections for use with a generator when Solar DC
power is not available.
1. Make sure the generator is powered off.
2. Make sure the external DC disconnect switch is off.
3. Connect the cables from the generator to the Terminal Block labeled "Back-up AC" and marked
L1, L2, and GND (Figure 6) (Torque specification: 15 in-lbs/ 1.7 N-m).

Flow Switch Wiring Connections

The SubDrive Solar controller makes use of a flow switch to protect the controller and motor when
there is not enough power to generate proper flow. The flow switch and sensor cable is included with
the SubDrive Solar QuickPAK and is required on all installations.
1. Connect the cables from the Flow Switch terminals NO and COM, and to the SubDrive Solar
terminal block labeled "TRIP" (Figure 7).

CAUTION
Failure to properly install the included flow switch will result in reduced system performance and may
result in system damage.
