NOTE: The motor and tacho polarities on the UCC T3 controller are software-configured during the installation process.  The maximum tacho voltage is 100 V.  If one terminal of the tacho is grounded, the maximum voltage is reduced to 18 V.  It is recommended that a differential tacho is used.

CAUTION: The UCC T3 motor connections must be blanked off if not being used to prevent accidental contact which could result in an electric shock.
