1.1 AC LINE INPUT CONNECTION – Connect the AC line input to Terminal Block TB1. See Section
6.1, on page 18.
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.
Model KBDA-24D – Terminals "L1", "L2" – Designed for single-phase AC line input only. Rated for
208/230 Volt AC line input with Jumper J1 set to the "230V" position (factory setting) and rated for
115 Volt AC line input with Jumper J1 set to the "115V" position. See Figure 10, on page 18.
Note: 230 Volts AC will be applied to the motor with 115 Volt AC line input.
Model KBDA-27D – Terminals "L1", "L2" – Designed for single-phase AC line input only. Rated for
208/230 Volt AC line input with Jumper J1 set to the "230V" position (factory setting) and
rated for 115 Volt AC line input with Jumper J1 set to the "115V" position. Rated for 1
maximum with 115 Volt AC line input and 2 HP maximum with 208/230 Volt AC line input.
See Figure 10, on page 18.
Note: 230 Volts AC will be applied to the motor with 115 Volt AC line input.
Model KBDA-29 – Terminals "L1", "L2", "L3" – Designed for single-phase or 3-phase AC line input.
Rated for 208/230 Volt AC line input only. Rated for 2 HP maximum with single-phase AC line input
(Terminals "L1", "L2") and 3 HP maximum with 3-phase AC line input (Terminals "L1", "L2", "L3").
See Figure 11, on page 19.
Models KBDA-45, 48 – Terminals "L1", "L2", "L3" – Designed for 3-phase AC line input only. Rated
for 400/460 Volt AC line input only. See Figure 11, on page 19.
1.2 AC LINE FUSING – It is recommended that a fuse(s) or circuit breaker be installed in the AC line.
Fuse each conductor that is not at ground potential. For the recommended fuse size, see Table 3,
on page 10. Also see Section 6.1, on page 18.
1.3 GROUND CONNECTION – Connect the ground wire (earth) to the Ground Screw, as shown in
Figures 10 and 11, on pages 18 and 19. Be sure the motor is also properly grounded. Two Ground
Screws are provided.
1.4 MOTOR CONNECTION – Connect the motor to Terminal Block TB1 Terminals "U", "V", "W", as
shown in Figures 10 and 11, on pages 18 and 19. Be sure the motor is properly grounded. Motor
cable length should not exceed 100 ft. (30 m) – special reactors may be required – consult our
Sales Department. See Section 6.3, on page 19.
1.5 60 Hz and 50 Hz MOTOR OPERATION – The drive is factory set for 60 Hz motors (Function No.
0.00 set to "0000"). For 50 Hz motors, set Function No. 0.00 to "0001", as shown in Figure 16, on
page 23. For other motor frequencies, set Function No. 0.00 to "0002".
1.6 JUMPER J1 SETTING (Models KBDA-24D, 27D Only) – Jumper J1 has been factory set for 230
Volt AC line input (installed in the "230V" position). For 115 Volt AC line input, set Jumper J1 to the
"115V" position. See Section 7, on page 20.
1.7 MOTOR OVERLOAD PROTECTION – Function No. 0.01 must be set to the motor nameplate cur-
rent for proper operation of the I 2 t Motor Overload Protection. See Figure 17, on page 24.
