Notes: 1. If a non-isolated signal is used, install the SIVFR – Signal Isolator (Part No. 9597). 2. Allows the motor to operate up to two times the
rated RPM. Constant motor horsepower will result when operating the drive in the “X2” mode above the motor rated frequency. 3. Dependent on
motor performance. 4. Do not operate the drive outside the specified AC line input voltage operating range.
