PRODUCT INFORMATION
Pump Sizing and Performance
8
The drive will operate many Franklin Electric surface mounted pumps, including C1, MH, BT4, DDS, and
VersaJet Pro series.
When operating a surface system, drives are configured based on motor current capacity rather than horse-
power. Motor current capacity is programmed through DIP switch settings. Refer to “
Maximum Amps (DIP
SW1 – Positions 1–5)” on page 23.
Pump Sizing and Performance
Maximum pump output using the drive is similar to the performance achieved using a pressure switch.
Therefore, the pump selection criteria are the same as if a pressure switch were used.
NOTE: The drive may result in 85-90% of pump performance when compared to other drive models, espe-
cially in applications with reduced input voltage.
Refer to the Franklin Electric AIM Manual for specific sizing information.
If an existing pump and motor have not been properly evaluated, or if the components of the well system
are not in good working order, the drive cannot be used to correct the problem or extend the life of aging
components.
Generator Sizing
Basic generator sizing for the drive is 1.5 times the maximum input watts consumed by the drive, rounded
up to the next normal-sized generator.
Recommended minimum generator sizes for the drive:
• 3500 watts nominal for up to 1 HP
• 5000 watts nominal for up to 2 HP
IMPORTANT: Do not use with a Ground Fault Circuit Interrupter (GFCI). If using an externally regulated gen-
erator, verify that the voltage and frequency are appropriate to supply the drive. This drive has not been
tested with inverter-controlled generators and AC-DC inverters.
