ii. SAFETY WARNING! — PLEASE READ CAREFULLY
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 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 enable 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.

GENERAL INFORMATION.
The KBMG-212D is a full-wave regenerative control, capable of operating a DC motor
(Permanent Magnet or Shunt) in a bidirectional mode. It provides 4-quadrant operation
which allows forward and reverse torque in both speed directions. The drive offers
excellent controllability, which closely approximates the performance of servo-type
drives. Ratings and specifications are presented in tables 1 and 3. Be sure the drive
is used within these ratings and specifications.

(Note: Regenerative drives normally produce more motor heating than standard
unidirectional SCR speed controls, especially under low speed operation. This
should be taken into consideration when specifying motor rating.)
