V1k KLC-Series Motor Protection Filter Installation
Instructions
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 airbourne dirt and dust, or
excessive vibration.

requirements of the National Electric Code (NEC)
and\or other applicable electrical codes.
• Ground the V1k Ouptut 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 V1k,
A1, B1 & C1.
• Wire the output power terminals, of the V1k, A2, B2
& C2 to the motor power connections.
• Make sure the VFD is set for operating modes and
ranges that are compatible with the V1k Output Filter.

and operating any equipment.

Product Specications
Wiring Diagram
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 V1k drive output lter is correct for the
application. e current rating of the V1k 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 V1k drive
output lter is not selected by the drive input current rating.
Properly sized and applied, TCI guarantees that the V1k
will limit motor terminal peak input votage to 150% of the
bus voltage with a wire lead length of 1000 feet and a carrier
frequency of 4kHz. Maximum lead length and carrier
frequency can vary depending on wire lead type. For best
performance, the V1k should be installed within 10 feet of
the drive.
Variable Frequency Drive Settings
Make sure that the variable frequency drive will be set for
operation modes and ranges that are compatible with the
V1k 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 and open panel unit
If you are mounting an open panel 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 V1k lter. TCI strongly recommends using
auxiliary cooling devices such as cooling fans, heat
exchangers, or possibley air conditioning units when
required to maintain the proper operating temperature.
e V1k must be mounted vertically on a smooth, solid
surface, free from heat, dampness, and condensation.
Mounting it verticallly is important for natural convection
cooling. A metal plate is provided to mount the V1k on a
composite surface.
Power Wiring
e conduit and wiring from the output of the variable
frequency drive to the motor must be routed to the V1k
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 line reactor
temperature is sensitive to lead wire oversizing. Avoid lead
wires more than ve times oversized by copper cross
sectional area regarldess of the material used. Use 75°C
copper conductors only or the equivalent, unlesss the wire
connector is marked for AI/Cu, then the use of aluminum
wire is permitted. Use only copper conductor on units
rated above 80 amps.
Wiring Cable Entry Locations
TCI has provided enclosure knock-outs on the two smaller
enclosures for incoming and outgoing power cables.
ese are located in a typical wiring location for customer
convenience. On the two larger size enclosures, 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 V1k 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 the 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.
