Based on a 5% voltage drop with 1000 ft limit.
Notes:
• Drive input voltage and motor nameplate voltage must match.
• The use of 600 V minimum rated motor cable is required.
• Maximum allowable wire lengths are measured between the controller and motor, based on
AIM Manual requirements with 1000 ft limit. Larger wire and filtering are required if exceeding
the 1000 ft limit.
• Flat-jacketed submersible motor cable is recommended. All splices in the motor cable must be
properly sealed with watertight shrink tubing. Use extreme caution to avoid damaging or
compromising the motor cable insulation during installation or service.
Conduit Locations and Sizing
Use appropriate strain relief or conduit connectors.
