Warning
Warning
Warning
Disconnect all power before working
on the equipment. Do not attempt any
work on a powered output lter.
e KLC, VFD, motor, and other
connected equipment must be properly
grounded.
e VFD terminals and connected
cables are at a dangerously high voltage
when power is applied to the VFD,
regardless of motor operation.
See www.transcoil.com for dimension tables
Please contact TCI Technical Support
or your TCI distributor for application
information regarding the use of KLC
output lters on the output side of the VFD.

KLC/KLCUL Output Filter
Installation Instruction
Installation Checklist
• Make sure that the installation location will not be exposed
to direct sunlight, rain or dripping liquids, corrosive liquids
or gases, explosive or combustible gases or dust, excessive
airborne dirt and dust, or excessive vibration.
• Select a mounting area that will allow adequate cooling air
and maintenance access.
• Make sure that all wiring conforms to the requirements of
the National Electric Code (NEC) and/or other applicable
electrical codes.
• Ground the KLC Output Filter to a dedicated system
ground to ensure safety and lter performance. Use a
properly sized grounding conductor.
• Wire the output power terminals of the VFD, T1(U), T2(V),
& T3(W) to the input terminals of the KLC lters L1, L2,
and L3.
• Wire the output power terminals, of the KLC, T1, T2, & T3
to the motor power connections.
• Make sure the VFD is set for operating modes and ranges
that are compatible with the KLC Output Filter.
• Check the entire system thoroughly before energizing and
operating any equipment.
When you receive the unit, you should immediately inspect
the shipping container and report any damage to the
shipping carrier who delivered the unit.
Verify the Application
Make sure the KLC output lter is correct for the application.
e current ratings of the KLC should be sized to handle
the FLA rating of the motor but not to exceed 110% of the
drive output current rating. is output lter is best applied
matched closely to the load. e KLC output lter is not
selected by the drive input current rating.
Vari a bl e Frequency Drive Settings
Make sure that the variable frequency drive will be set for
operation modes and ranges that are compatible with the
KLC output lter:
• Maximum output frequency: 60 Hz
• PWM switching frequency best between 2kHz and 4kHz
• Mode of operation: Do not use with DC braking unless
the drive application has been conrmed by TCI
Technical Support.
• Do not use on overhauling loads without bus voltage
control.
Mounting an open style unit
If you are mounting an open style unit in your own
enclosure, you must provide an enclosure that is adequately
sized and ventilated suciently to prevent overheating. e
lter is designed with a maximum ambient temperature of
40°C (104°F). If the ambient temperature exceeds this value
it is the responsibility of the customer to provide auxiliary
cooling to reduce the ambient operating temperature
around the KLC lter. TCI strongly recommends using
auxiliary cooling devices such as cooling fans, heat
exchangers, or possibly air conditioning units when
required to maintain the proper operating temperature.
Position the KLC lter to be as close as possible (No greater
than 20 .) from the drive output terminals. e KLC must
be mounted so that the included line reactor is positioned
vertically. Mounting it vertically is important for natural
convection cooling.
Power Wiring
e conduit and wiring from the output of the variable
frequency drive to the motor must be routed to the KLC
and then to the motor. TCI recommends a separate
dedicated conduit run for each drive/lter/motor run
unless properly shielded and segregated wiring procedures
are practiced. Parasitic and induced capacitance can greatly
reduce the eectiveness of the lter performance. Under
no circumstances should you wire both control and power
wire in the same conduit unless the wire way is specically
designed for this practice. e unit temperature is
sensitive to lead wire oversizing. Avoid lead wires more
than ve times oversized by copper cross sectional area
and operating current, regardless of the material used. Use
75°C copper conductors only or the equivalent, unless
the wire connector is marked for Al/Cu, then the use of
aluminum wire is permitted. Use copper conductor only
on units rated above 80 amps.
Wiring Cable Entry Locations
TCI has not provided knock-outs due to the wide
variety of application requirements. TCI allows
installing electricians the option of locating the cable
openings at a point of their choosing.
Grounding
e KLC lter must be connected to the ground of
the premises wiring system. is can be conducted
by identifying a known premises ground near by the
lter or running a special ground dedicated for this
application. e ground connection must be made
using a wire conductor. Metallic conduit is not a
suitable grounding conductor. e integrity of all
ground connections should be periodically checked.
