Notes: 1. Requires an isolated signal. If a non-isolated signal is used, or if using 0 to ±2.5 thru 0 to ±25 Volts DC, or 4 – 20 mA DC signal input,
install the SIAC Signal Isolator (Part No. 9600). 2. Allows the motor to operate up to two times the rated RPM. Constant 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.
