Important Replacement Information:
Endura Pro constant torque motors are no longer being manufactured and have been replaced with Ensite motors. Replacement kits now include an Ensite motor along with the necessary adapter harness to convert back to Endura Pro connections when required.
Programmed Ensite Motor Kit Includes:
Ensite Motor Ensite to Endura Pro Adapter Harness (107246-01) Installation Instructions (508282-01) Two Zip Ties
Connector Differences:
Endura Pro motors feature a single large 9-pin connector. Ensite motors use two separate connectors: a 3-pin power connector and a 6-pin low-voltage speed tap connector.
If replacing an existing Endura Pro motor, the included Ensite to Endura Pro adapter harness (107246-01) must be used. If replacing an existing Ensite motor, the adapter harness is not required.
