General Safety Instructions
Warning
Warning
Warning
Be sure to read, understand, and
follow all safety instructions.
Only qualified electricians should
carry out all electrical installation and
maintenance work on reactors.
All wiring must be in accordance with
the National Electrical Code (NEC)
and/or any other codes that apply to
the installation site.
Recommendations and Considerations
When installing the KLR/KDR Reactors on
the OUTPUT side of the Variable
Frequency Drive (VFD), please use the
following guidelines:
TCI recommends 1.5% impedance
reactors to be used on the output of the
VFD. In the case of the KDR line, use only
the KDROUTPUT reactors.
Reactors should be mounted as
close to the output terminals of the VFD as
possible.
TCI suggests that the reactor be
used in applications where the motor lead
length is less than 100 feet. For
applications with motor lead lengths greater
than 100 feet, TCI offers KLC/KLCUL
Output Filters and KMG MotorGuard High
Performance Sinewave Filters.
Reactors are sized by the Full Load
Amps located on the motor nameplate.

Warning
Warning
Warning
Disconnect all power before working
on the equipment. Do not attempt any
work on a powered reactor.
The reactor, VFD, motor, and other
connected equipment must be
properly grounded.
The VFD terminals and connected
cables are at a dangerously high
voltage when power is applied to the
VFD, regardless of motor operation.
Please contact TCI Technical Support or your
TCI distributor for application information
regarding the use of these reactors on the
load or output side of the VFD, or in
applications where inductors are used.

Installation Instruction
INPUT
Recommendations and Considerations
When installing the KLR/KDR Line Reactors
on the INPUT side of the Variable
Frequency Drive (VFD), please use the
following guidelines when wiring the unit:
The KLR/KDR Line Reactor is a 3phase device and should be wired in series
and positioned on the input side of the VFD.
TCI recommends that these reactors
be wired as close to the front end of the VFD
as possible.
In standard 40° C ambient or less
installations, a clearance of 3 inches on all
sides of the reactors and its enclosure is
recommended for assisting in heat
dissipation and ample wire bending space.
This is a general guideline for typical
applications. If the reactor is being installed
next to a heat sensitive instrument or control
device, we recommend reviewing specific
requirements or heat limitations. Line reactor heat loss information is available in the
standard TCI product literature or on the web
at Trans-Coil website.
Field Wiring Information
Below is the typical wiring diagram for the 3-phase
reactor applied to the front end of the Variable
Frequency Drive (VFD).
Single-phase applications are acceptable, however, it is important to size the unit based on the single phase Full Load Amperage of the VFD. The
input and output connections should be on terminals A and C to ensure proper performance.
Wiring Diagram
LOAD
All Terminal Block connectors will be
marked. A1, B1, and C1 are the input
terminals where the 3 phases of incoming
power are to be wired. As a result, A2, B2,
and C2 are the output terminals. Units with
copper bus or ring lug terminals are not
marked. In these cases, either the upper
terminals or the lower terminals can be used
as the input terminals, as long as the selection is consistent. For example, if an upper
terminal is selected as the input, all upper
terminals must be input terminals. Wiring
from the output terminals should connect to
the input of the VFD.
Refer to NEC wiring practices for
appropriate wire sizes for your application.
These reactors are designed to be
floor-mounted, or wall-mounted. Large
open-style devices should be panel
mounted by incorporating a bracket that
would act as a shelf to support the reactor
and/or enclosure. When installing an open
style device in an existing control cabinet,
drive cabinet, motor control center, or other
large enclosure, the reactor should be
mounted in the lower half of the cabinet to
prevent hot spots or pockets of heat.
Locating the reactor in the lower half of the
cabinet typically allows better thermal
dissipation and heat convection.
The KLR/KDR input line reactor
should be located as close to the drive as
possible to have the greatest success in
both protecting the VFD as well as mitigating
line harmonics. We recommend this be 10
feet of cable or less.

* For single-phase applications, use coils
A and C. Isolate terminals B1 and B2.
