Installation and Use Tips
-
Ensure your supply meets the 230/460 V dual-voltage specification and confirm compatibility with your VFD if used.
-
Although usable at 208 V, verify motor current and load conditions when used in lower voltage systems.
-
The TEFC enclosure and rugged build allow for installation in harsher environments, but ensure adequate cooling and airflow around the motor.
-
Torque up bolts to manufacturer specs and align load carefully to minimize vibration and extend bearing life.
