Reactor
Installation
Guide
Performance and Protection for Drives
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 KDR OUTPUT 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.
OUTPUT
Recommendations and Considerations
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.

Warning
!
Warning
Be sure to read, understand, and
follow all safety instructions.
!
Warning
Only qualified electricians should
carry out all electrical installation and
maintenance work on reactors.
!
Warning
All wiring must be in accordance with
the National Electrical Code (NEC)
and/or any other codes that apply to
the installation site.
Disconnect all power before working
on the equipment. Do not attempt any
work on a powered reactor.
Warning
The reactor, VFD, motor, and other
connected equipment must be
properly grounded.
Warning
The VFD terminals and connected
cables are at a dangerously high
voltage when power is applied to the
VFD, regardless of motor operation.
