Note:
• Torque characteristics are different than when you operate the motor directly from line power. Make sure that you understand the load
torque characteristics for the application.
• The current rating of submersible motors is usually higher than the current rating of standard motors for a given motor power. Make
sure that the rated output current of the drive is equal to or more than the current rating of the motor. If the motor wire length is longer
than 100 m (328 ft), select the correct wire gauge to adjust for a loss in voltage and prevent a loss of motor torque.
• Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the
drive. Unshielded wire can cause electrical interference and unsatisfactory system performance.
