RECONDITIONIONG THE BUS CAPACITORS
If this drive has been in storage for over one year it is necessary to recondition the power supply bus capacitors. To recondition the bus
capacitors, apply the AC Line, with the drive in the Stop Mode, for a minimum of one hour. Not following this procedure will cause the bus
capacitors to fail.

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 (ASD-24D, 27D ONLY) (J1)
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 13.
CAUTION!
The rated AC Line voltage of the drive must match the actual
AC Line input voltage. On ASD-24D, 27D the setting of Jumper J1 must match
the actual AC Line input voltage.
10.2
– MOTOR HORSEPOWER SELECTION (J2)
Jumper J2 must be set to the corresponding position for the motor being used. See Figure 14.

115 Volt AC Line input and 2 HP maximum with 208/230 Volt AC Line input. ***ASD-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" or "AUTO" 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 15.
If Jumper J3 is set to the "M" or "MAN" position, the drive will have to be manually restarted for a
momentary power loss. Also see Section 13.2 on page 18 for the Status (ST) LED indication.
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 16 and 17.
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 set Jumper J4 to the "1X" position. See Figure 16.
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 17.
