IMPORTANT – You must read these simplified operating instructions before you proceed.

These instructions are to be used as a reference only and are not intended to replace the

detailed instructions provided herein.  You must read the Safety Warning before proceeding.

A.  AC Line – Wire AC line voltage (230VAC ±10%, 50/60 Hz).  Connect ground wire

(earth) to green ground screw.

1. Permanent Magnet (PM Type).  Connect motor armature leads to M1+ and M2-. 
2. Shunt Wound Motors.  Connect motor armature as above.  Connect full voltage

shunt field wires (180 volt motors with 200 volt fields) to F+ and F-.  Connect half

voltage field wires (180 volt motors with 100 volt fields) to F+ and L1.

Jumper J7 is factory set for speed control operation (SPD).  For torque control, set J7 to

TRQ position.  Note: J8 must be set to “S/LT” position for speed control operation.

All trimpots have been factory set in accordance with figure 1, page 3.

The KBRG-255 does not contain AC line or armature fusing.  It is recommended that a 40

Amp fuse or circuit breaker be installed on each AC line conductor not at ground potential.

Do not fuse ground or neutral wires.

Connect potentiometer or  isolated analog input to terminal “10,” “11,” “12" and “13"

according to section V, E and F, on pages 7 and 9.  Do not ground (earth) signal inputs.

Use a signal isolator when controlling multiple drives from a non isolated signal source.

This product should be installed and serviced by a qualified technician, electrician or electrical

maintenance person familiar with its operation and the hazards involved.  Proper installation, which
includes wiring, mounting in proper enclosure, fusing or other overcurrent protection and grounding,
can reduce the chance of electric shocks, fires or explosion in this product or products used with
this product, such as electric motors, switches, coils, solenoids and/or relays.  Eye protection must
be worn and insulated adjustment tools must be used when working with control under power.  This
product is constructed of materials (plastics, metals, carbon, silicon, etc.) which may be a potential
hazard.  Proper shielding, grounding and filtering of this product can reduce the emission of radio
frequency interference (RFI) which may adversely affect sensitive electronic equipment.  If
information is required on this product, contact our factory.  It is the responsibility of the equipment
manufacturer and individual installer to supply this safety warning to the ultimate user of this
product.  (SW effective 11/92)

This control contains electronic Start/Stop and Inhibit circuits that can be used to start and

stop the control.  However, these circuits are never to be used as safety disconnects since they are
not fail-safe.  Use only the AC line for this purpose.

The input circuits of this control (potentiometer, start/stop, Inhibit) are not isolated from AC

line.  Be sure to follow all instructions carefully.  Fire and/or electrocution can result due to
improper use of this product.
