*1 ft = 0.305 m
NOTES:
• The use of 600 V minimum rated motor cable is required.
• SubDrive models show cable lengths for highest power motor supported by each model.
• A 10-foot (3.05 m) section of cable is provided with the SubDrive/MonoDrive to connect the analog pressure transducer.
• Maximum allowable wire lengths are measured between the controller and motor.
• Aluminum wires should not be used with the SubDrive/MonoDrive.
• All wiring to comply with the National Electrical Code and local codes.
• MonoDrive minimum breaker amps may be lower than AIM Manual specifications for the motors listed due to the soft-
starting characteristic of the MonoDrive controller.
• SubDrive minimum breaker amps may appear to exceed AIM Manual specifications for the motors listed because
SubDrive controllers are supplied from a single-phase service rather than three-phase.
• Motor Overload Protection Note: The drive electronics provide motor overload protection by preventing motor current
from exceeding the maximum Service Factor Amps (SFA). Motor overtemperature sensing is not provided by the drive.
• Flat-jacketed submersible motor cable is recommended. All splices in the motor cable must be properly sealed with the
appropriate watertight shrink tubing. Extreme caution must be taken, especially when using non-jacketed motor cable,
to avoid damaging or compromising the motor cable insulation during installation
or service. Improper splicing or damage to motor cable insulation may expose the conductor(s) to moisture and can
produce motor cable failure.
Generator Sizing
Basic generator sizing for the Franklin Electric SubDrive/MonoDrive system is 1.5 times
the maximum input watts consumed by the drive, rounded up to the next normal-sized
generator.
Recommended minimum generator sizes:
MonoDrive C
1/2 hp = 2000 Watts (2 kW)
3/4 hp = 3000 Watts (3 kW)
1 hp = 3500 Watts (3.5 kW)
MonoDriveXT C
1.5 hp = 4000 Watts (4 kW)
2 hp = 5000 Watts (5 kW)
NOTE: Not to be used on a Ground Fault Circuit Interrupter (GFCI). If using an externally regulated generator, verify that the
voltage, Hertz and idle speed are appropriate to supply the drive.
