i. 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 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 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.
Be sure to follow all instructions carefully. Fire and/or electrocution can result due to improper
use of this product.
This product complies with all CE directives pertinent at the time of manufacture. Contact
factory for detailed installation instructions and Declaration of Conformity.

I. INTRODUCTION
Thank you for purchasing the SIVF Signal Isolator (P/N 9474). KB Electronics, Inc. is committed to providing total customer satisfaction by producing high quality products that have
been manufactured to the highest standards and techniques in the industry. The SIVF is
engineered with state-of-the-art surface mount technology (SMT) incorporating advanced
circuitry in a relatively small and user friendly package, making it convenient to operate and
easy to install.
The SIVF is used to isolate, amplify, and condition DC voltage and current signals from any
source (power supplies, motors, tachometer generators, transducers, and potentiometers).
The isolated output voltage of the SIVF provides input signals to all models of the KBVF
Adjustable Frequency Drive (P/N 9957, 9958, 9959, 9977, 9978, and 9979). Signal input
and motor direction control is performed by making connections to the on-board barrier terminal. All inputs (+5V, SIG, COM, FWD & REV) to the SIVF are isolated from the AC line
and motor connections.
The SIVF is factory calibrated to accept signal input voltage (0 – 5V DC), current (4 – 20mA
DC), or a potentiometer (5KΩ) via a jumper selection. MIN and MAX trimpots are provided
in order to readjust the SIVF. This allows the use of 0 – 2.5 thru 25V DC input voltage signals for customizing specific applications.

II. INSTALLATION INSTRUCTIONS
See figure 2, SIVF Connection Diagram, on page 5.
WARNING: HIGH VOLTAGE IS
PRESENT WHILE LEDs ARE ILLUMINATED.
Before wiring the SIVF to the KBVF, disconnect all power to the KBVF and wait until “PWR”
and “ST” LEDs are no longer illuminated.
A. Wiring the SIVF to the KBVF – (Note: Do not install the SIVF to the KBVF until wiring
is completed.)
1. Remove the F-S-R jumper which is installed on CONN2 of the KBVF. Attach the
3-pin connector (with white, black, and red wires) from the SIVF to the KBVF connector marked “CONN2”.
2. Attach the red wire from the SIVF to the KBVF terminal marked “J3”.
3. Attach the orange wire from the SIVF to the KBVF terminal marked “P2”.
