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. 5. See Table 4 below.
