KBAC SERIES INSTALLATION AND OPERATION MANUAL

10 – SETTING SELECTABLE JUMPERS
The drive has customer selectable jumpers which must be set before the drive can be used.
WARNING!
HIGH VOLTAGE
! Disconnect the AC Line before changing position of jumpers.
10.1 – AC LINE INPUT VOLTAGE SELECTION (KBAC-24D, 27D ONLY) (J1)
CAUTION!
The rated AC Line voltage of the drive must match the actual
AC Line input voltage. On KBAC-24D, 27D the setting of Jumper J1 must
match the actual AC Line input voltage.
Jumper J1 is factory installed on Terminal "230V" for 208/230 Volt AC Line
input. For 115 Volt AC Line input, the jumper must be removed and installed
on Terminal "115V". To remove the terminal, use pliers to gently rock the
terminal back and forth while pulling it upward. See Figure 22.
10.2 – MOTOR HORSEPOWER SELECTION (J2)
Jumper J2 must be set to the corresponding position for the motor being used. See Figure 23.

KBAC-27D: Rated 1½ HP maximum with 115 Volt AC Line input and 2 HP maximum with 208/230 Volt AC Line input.
***
KBAC-29:
Rated 2 HP maximum with 1-phase AC Line input and 3 HP maximum with 3-phase AC Line input.
10.3 – AUTOMATIC RIDE-THROUGH OR MANUAL START SELECTION (J3)*
Jumper J3 is factory set to the "A" position for Automatic Ride-Through. If the power is
interrupted for up to 2 seconds, the drive will shut down and then "ride-through" and
automatically return to the set frequency. See Figure 24.
If Jumper J3 is set to the "M" position, the drive will have to be manually restarted for a
momentary power loss using the Start/Stop Switch. Also see Section 13.2 on page 23
for the Status (ST) LED indication.
*
On KBAC-24D, 217, 217S, 217F, 217SF, 416, 416S, 416, 416F, 416SF Jumper J3 is
labeled "AUTO" and "MAN".
10.4 – MOTOR FREQUENCY SELECTION (J4 AND J5)
Both Jumpers J4 and J5 must be set for the appropriate motor nameplate frequency rating. See Figures 25 and 26.
10.4.1 – SETTING THE DRIVE FOR 60 Hz OR 50 Hz MOTOR OPERATION
The drive is factory set to operate 60 Hz motors. Jumper J4 is factory set to the "1X"
position and Jumper J5 is factory set to the "60Hz" position. For 50 Hz motors, set
Jumper J5 to the "50Hz" position, and be sure Jumper J4 is set to the "1X" position.
See Figure 26.
10.4.2 – SETTING THE DRIVE FOR TWO TIMES THE RATED MOTOR RPM
The drive can also operate the motor up to two times the rated RPM. However,
constant horsepower will result when operating the drive in the “2X” mode above the
motor rated frequency. For 120 Hz output with 60 Hz motor, set Jumper J4 to the
"2X" position and be sure Jumper J5 is set to the "60Hz" position. For 100 Hz output
with 50 Hz motor, set Jumper J4 to the "2X" position and set Jumper J5 to the "50Hz"
position. See Figure 26.
