SubDrive/MonoDrive

Fuse/Circuit Breaker and Wire Sizing

The Listed fuse/Listed circuit breaker size and maximum allowable wire lengths for connection to the 
SubDrive/MonoDrive are given in the following tables:

A 10-foot (3.05 m) section of cable is provided with the SubDrive/MonoDrive to connect the pressure sensor.

NOTE:

•  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/or 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.
