  • A 10-foot (3.05 m) section of cable is provided with the SubDrive/MonoDrive to connect the pressure sensor.
  • 1 ft = 0.305 m
  • 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.Amps (SFA). Motor overtemperature sensing is not provided by the drive.
  • Motor Overload Portection: 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.
