1 QUICK-START INSTRUCTIONS

Important – You must read these simplied instructions before proceeding. These instructions are to

be used as a reference only and are not intended to replace the details provided herein. You must read

the Safety Warning on page 5 before proceeding.

Reconditioning 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.

See Figure 1. Also see Section 4 - Important Application Information on Page 13.

WARNING! Disconnect main power before making connections to the drive.

1.1 AC Line Input Connection – Wire the AC line input to Terminal Block TB1. See Section 5.1

on pages 14 – 15.

Application Note: Do not wire this drive to a GFCI. If operation with a GFCI is required, contact

our Sales Department.

Note: The rated AC line voltage of the drive must match the actual AC line input voltage. On Models

KBAC-24D and 27D, the setting of Jumper J1 must match the AC line input voltage.

Models KBAC-24D, 27D, 29 (1P): Designed to accept single-phase (Terminals “L1”, “L2”) AC line

input only. Rated for 208/230 Volt AC line input with Jumper J1 set to the “230V” position (factory

setting). Rated for 115 Volt AC line input with Jumper J1 set to the “115V” position. See Figure 7

on page 14.

Note: Model KBAC-27D is rated for 11⁄2 HP maximum with 115 Volt AC line input and 2 HP maximum

with 208/230 Volt AC line input.

Model KBAC-29: Designed to accept single-phase (Terminals “L1”, “L2”) or 3-phase (Terminals “L1”,

“L2”, “L3”) AC line input. Rated for 208/230 Volt AC line input only. See Figure 8 on page 15.

see Section 5.2 on page 15.
