Pump/Motor Wiring Connections; Control Switch Wiring Connections (Optional) - Franklin Electric SubDrive Solar Manuel D'installation

Pump/Motor Wiring Connections

1. Connect the cables from the Pump/Motor Assembly to the Terminal Block labeled "MOTOR"
and marked BLK, RED, YEL, and GND (Figure 8) (Torque specification: 15 in-lbs/ 1.7 N-m).
2. Motors with international leads use Table 2 for motor lead color information to ensure
correct installation.

CAUTION
For retrofit application, make sure to check integrity of power and motor leads. This requires
measuring the insulation resistance with the suitable megohmmeter. Reference the Franklin Electric
AIM for correct measures (see Table 4. Motor Specifications, pg. 25)
Control Switch
Wiring Connections (Optional)
The SubDrive Solar controller can be operated with control switches to control the ON/OFF
pumping range. Use a normally closed low-voltage control switch with a contact rating suitable for
instrumentation use (i.e. Max: 24 V 15mA)
1. Connect the cables from the "STOP" control switch to the Terminal Block labeled "STOP".
2. Connect the cables from the "RUN" control switch to the Terminal Block labeled "RUN" (Figure 9).
