FIRE OR ELECTROCUTION CAN RESULT DUE TO IMPROPER USE OF THIS
PRODUCT. READ SAFETY WARNING ON PAGE 5.
4.1 Motor Type – The KBRG-212D is full-wave regenerative control, capable of
operating a DC motor (Permanent Magnet (PM), or Shunt), in a Bi-Directional mode.
Be sure the drive is used within its stated specifications.
4.2 Torque Requirements – When replacing an AC induction motor with a DC motor
and speed control, consideration must be given to the maximum torque
requirements. The full load torque rating of the DC motor must be equal to, or
greater than, that of the AC motor.
4.3 Acceleration Start – The KBRG-212D contains an adjustable acceleration
start feature that allows the motor to smoothly accelerate from 0-full speed over a
time period of 0.5 to 15 seconds.
4.4 Limitation in Use – The KBRG-212D controls are designed for use on
machine applications.
CAUTION!
- Do not use in explosive atmosphere. Be sure the KBRG-212D is
used within its maximum ratings. Follow all installation instructions carefully (Refer to
Sections 4 and 5).
5 MOUNTING INSTRUCTIONS
Mount the KBRG-212D on a flat surface free of moisture, metal chips, or corrosive
atmosphere. Refer to Figure 2, on page 11.
A 5kΩ ohm remote potentiometer is provided. Install the potentiometer using hardware
provided. Be sure to install insulating disk between potentiometer and inside of front panel.
Enclosure – When mounting the KBRG-212D in an enclosure, it must be large enough to
allow for proper heat dissipation. A 12” x 12” x 24” enclosure is suitable for the KBRG-212D at
full rating. Smaller enclosures may be used if full rating is not required.
