1. coasting to a stop is recommended for frequent starts and stops Frequent starting and stopping can produce high torque This may cause damage to motors Do not disconnect any of the motor leads from the drive unless power is removed or the drive is disabled Opening any one lead while the drive is running may destroy the drive Under no circumstances should power and logic level wires be bundled together Be sure potentiometer tabs do no make contact with the potentiometer enclosure Grounding the input will cause damage to the drive Caution should be taken when operating fan cooled motors at low speeds because their fans may may not move sufficient air to properly cool the motor Minarik Drives recommends inverter duty motors when the speed range is beyond 10 1 Drive is designed to work with permanent split capacitor shaded pole and standard three phase induction motors In general the drive can work with capacitor start motors but it is conditional on the current pull when the capacitor is in effect and how long the application calls for a speed that the capacitor will stay in the auxiliary winding MTT ML ALL DIMENSIONS IN INCHES MILLIMETERS Connections POWER Line Input Connect the AC line power leads to terminals L1 and L2 115 or to a single throw single pole master power switch recommended The switch should be rated at a minimum of 1202.
