Notes: 1. Do not operate the drive outside the specified AC line input voltage operating range. 2. The drive is factory set for 208/230 Volt AC line input
(Jumper J1 not installed). For 115 Volt AC line input, install Jumper J1 (supplied). See Figure 9, on page 16. 3. Allows the motor to operate up to two times
the rated RPM. Constant motor horsepower will result when operating the drive in the “2X” mode above the motor nameplate rated RPM. 4. Dependent on
motor performance.

Notes: 1. The drive is factory set for 208/230 Volt AC line input (J1 not installed). For 115 volt AC line input, install Jumper J1 (supplied). See Figure 9, on
page 16. 2. Model KBMA-24DF contains a built-in AC line Class A RFI (EMI) filter which meets the CE Council Directive 89/336/EEC Industrial Requirement.
