Battery to supply power for absolute encoder output from the TL-Series motors to the motor feedback connector on the drive must be installed in the Low Profile Connector
Kit for Motor Feedback, catalog number 2093-K2CK-D15M. Refer to publication 2093-IN005x-EN-P for information on wiring and installing this connector kit.
