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-PS Signal Isolator with Power Supply. 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 specied AC Line input voltage operating range. 5. See Table 4 on page 14.
