coded Pulse Width Modulated (PWM) output provides high motor efficiency and low noise. Adjustable
Linear Acceleration and Deceleration make the drive suitable for soft-start applications.
Due to its user-friendly design, the KBDA is easy to install and operate. Setting the drive to specific appli-
cations is accomplished using the Multi-Function Keypad, which provides easy operation and
programming of the drive. To facilitate programming, all similar functions are presented in common
groups. For more advanced programming, PC based Drive-Link™ software is available.
The 4-Digit LED Display provides readout of drive operating parameters and programming functions and
displays Output Frequency, Motor RPM, Output Current, Output Voltage, Bus Voltage, Function Codes
and Values, Fault Codes, and Custom Units. In addition to operating the drive, the Multi-Function Keypad
is used to change drive operating parameters, reprogram functions, and change the display output. The
LEDs provide indication of the drive’s status and operating mode ( z, PGM, LCL/REM, STOP, FWD,
REV, OL, JOG/REM).
The optional IODA Input/Output Multi-Function Board provides a variety of functions, which include pre-
set frequency, up/down frequency control, signal isolation, isolated output voltage for controlling auxiliary
devices, open collector outputs, and output relay contacts. See Appendix A, on pages 42 – 54. See

4 IMPORTANT APPLICATION INFORMATION
4.1 MOTOR WITH EXTERNAL FAN COOLING – Most totally enclosed fan-cooled (TEFC) and open
ventilated 3-phase AC induction motors will overheat if used beyond a limited speed range at full
torque. Therefore, it is necessary to reduce motor load as speed is decreased.
Note: Some fan-cooled motors can be used over a wider speed range. Consult the motor
manufacturer for details.
WARNING! Some
motors have low
speed characteristics,
which cause overheating
and winding failure under
light load or no load condi-
tions. If the motor is oper-
ated in this manner for an
extended period of time, it
is recommended that the
unloaded motor current be
checked from
2 – 15 z (60 – 450 RPM)
to ensure motor current
does not exceed the
nameplate rating. If the
motor current exceeds the
nameplate rating, the
Boost value may have to
be decreased (see
Function No. 3.11). Do
not use motor if the
motor current exceeds
the nameplate rating.
It is recommended
that the drive be
used with Inverter Duty
or TENV motors.
Inverter duty and most totally enclosed non-ventilated (TENV) motors can provide full rated torque
over an extended speed range without overheating. See Figure 8.
If external fan cooling is provided, open ventilated motors can also achieve an extended speed
range at full rated torque. A box fan or blower with a minimum of 100 CFM per P is recommend-
ed. Mount the fan or blower so the motor is surrounded by the airflow. See Figure 9.
4.2 ELECTRONIC MOTOR OVERLOAD PROTECTION – The drive contains Modified I2t Overload
Protection.* Part of this function consists of a Current Limit (CL) circuit, which limits the drive cur-
rent to a preset level of 160% of the Motor Nameplate Rated Current setting. The factory setting
for motor nameplate current is the drive rated current, which must be set to the actual
motor nameplate current (see Important Application Information (Item 2), on page 4). See
Table 3, on page 10. Also see Function No. 0.01, on page 32.
Standard I2t is undesirable because it causes nuisance tripping. It allows a very high motor current
to develop and will turn the drive off after a short period of time. KB’s RMS Current Limit Circuit
avoids this nuisance tripping while providing maximum motor protection.

If the motor is overloaded to 120% of the Motor Nameplate Rated Current setting, the I2t
Timer starts. If the motor continues to be overloaded at the 120% level, the timer will shut
down the drive after 30 minutes. If the motor is overloaded to 160% of full load, the drive will
trip in 6 seconds.
*UL approved as an overload protector for motors.
5 MOUNTING INSTRUCTIONS
It is recommended that the drive be mounted vertically on a flat surface with adequate ventilation. Leave
enough room below the drive to allow for AC line, motor connections, and any other connections that are
required. Although the drive is designed for outdoor and washdown use, care should be taken to avoid
extreme hazardous locations where physical damage can occur. When mounting the drive in an enclo-
sure, the enclosure should be large enough to allow for proper heat dissipation so that the ambient tem-
perature does not exceed 45°C (113 °F) at full rating. The recommended mounting screw size is 1/4 inch
(M6). See Figures 6 and 7, on pages 14 and 15.
WARNING! Do not use this drive in an explosion-proof application.
Be sure the drive is securely mounted.
6 ELECTRICAL CONNECTIONS
WARNING! HIGH VOLTAGE – Read Safety Warning, on page 6, before using the drive.
Disconnect main power before making connections to the drive. To avoid electric shock,
be sure to properly ground the drive.
Application Note: To avoid erratic operation, do not bundle the AC line and motor wires with each
other or with wires from signal following, start/stop contacts, or any other signal wires. Also, do not
bundle motor wires from multiple drives in the same conduit. Use shielded cables on all signal wires
over 12” (30 cm). The shield should be earth grounded on the drive side only. Connect the drive in
accordance with the National Electrical Code requirements and other local codes that may apply.
Be sure to properly fuse each AC line conductor that is not at ground potential. Do not fuse neutral
or grounded conductors. A separate AC line switch or contactor must be installed as a disconnect
so that each ungrounded conductor is opened. For fuse or circuit breaker selection, see Table 3, on
page 10. Also see Section 6.1, on page 18.
To maintain the watertight integrity of the drive, be sure to use suitable liquidtight ttings and wires
that are appropriate for the application. odel KBDA-24D contains mounting holes for standard 1/2”
liquidtight ttings (not supplied) (two liquidtight plugs are provided, if only one knockout is used).
odels KBDA-27D, 29, 45, 48 contain two mounting holes for standard 1/2” liquidtight ttings (not
supplied) and one mounting hole for standard 3/4” liquidtight tting (not supplied) (two liquidtight
plugs are provided, if only one knockout is used). The Liquidtight Fittings Kit (Part No. 9526) is avail-
able for all models (see Table 1, on page 9).
The drive is designed with a hinged case so that, when the front cover is open, all wires stay intact.
To open the cover, the four screws must be loosened so they are no longer engaged in the case
bottom. After mounting the drive and all electrical connections are complete, close the cover making
sure that the wires do not get caught or crimped as the cover is closed. Tighten the four screws so
that the gasket is slightly compressed. The recommended tightening torque is 12 in-lbs (14 kg-cm).
See Figures 6 and 7, on pages 14 and 15, for the tightening sequence. Do not overtighten.

6.1 AC LINE INPUT CONNECTION (see Warning, on page 17) – Connect the AC line input to
Terminal Block TB1. See Electrical Ratings, Table 3, on page 10.
Application Note: If operation with a Ground-Fault Circuit-Interrupter (GFCI) is required, see
Function No. 0.04, on page 32.
Note: The rated AC line voltage of the drive must match the actual AC line input voltage. On
Models KBDA-24D, 27D, the setting of Jumper J1 must match the AC line input voltage.
AC Line Fusing –The drive does not contain line fuses. Most electrical codes require that each
ungrounded conductor contain circuit protection. Do not fuse neutral or ground connections.
It is recommended to install a fuse (Littelfuse 326, Buss ABC, or equivalent) or a circuit breaker
(Square D QOU or equivalent) in series with each ungrounded conductor. Do not fuse motor
leads. For the recommended fuse size, see Table 3, on page 10.
Connect the drive in accordance with the National Electrical Code requirements and other local
codes that may apply to the application.

8 RECOMMENDED HIGH VOLTAGE DIELECTRIC WITHSTAND TESTING (HI-POT TESTING)
Testing agencies such as UL, CSA, VDE, etc., usually require that equipment undergo a hi-pot test. In
order to prevent catastrophic damage to the drive, which has been installed in the equipment, the follow-
ing procedure is recommended. A typical hi-pot test setup is shown in Figure 15, on page 21. All drives
have been factory hi-pot tested in accordance with UL requirements.
WARNING! All equipment AC line inputs must be disconnected from the AC power.
8.1 Connect all equipment AC power input lines together and connect them to the .V. lead of the hi-
pot tester. Connect the RETURN lead of the hi-pot tester to the frame on which the drive and other
auxiliary equipment are mounted.

Do not connect the AC line input until Jumper J1 is set for the proper input voltage
being applied to the drive. Catastrophic failure will occur if a 230 Volt AC line is applied
when the drive is set for 115 Volt AC line input.
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”. See Figures 13 and 14.
