Performance Guarantee
Select and install the appropriate HarmonicGuard®Passive Harmonic
Filter in a variable torque, variable frequency AC drive application, within
our published technical specifications and we guarantee that the input
current distortion will be less than or equal to 5% THID for standard
HarmonicGuard Series filters at full load, and less than 8% at 30% load.
If a properly sized and installed filter fails to meet its specified THID level,
TCI will provide material for necessary modifications or replacement
filter at no charge.
HarmonicGuard filters can also provide similar performance in other
drive applications such as constant torque, DC drives and other phase-
controlled rectifiers, but actual THID levels can vary by load and/or
speed and therefore cannot be guaranteed. Consult factory for
assistance when applying HarmonicGuard filters on these types of
equipment.
MINIMUM SYSTEM REQUIREMENTS:
The guaranteed performance levels of this filter will be achieved
when the following system conditions are met:
Frequency: 50 Hz / 60Hz ± 0.75Hz
System Voltage: Nominal System Voltage (line to line) ±10%
Balanced Line Voltage: Within 0.5%
Background Voltage Distortion: < 0.5% THVD
The input VFD current waveform shall be consistent with that of a
VFD with 3% AC line reactance at full load.
NOTE: The presence of background voltage distortion will cause motors
& other linear loads to draw harmonic currents.
Additional harmonic currents may flow into the HarmonicGuard filter if
there is harmonic voltage distortion already on the system.
If higher levels of harmonic voltage distortion (2%-5%) are present,
please use the high background distortion version of the
HarmonicGuard filter.
*For PQconnect: To run PQvision software, minimum system
requirements are Windows 7 and 1280x720 resolution.

Verify the Application
Make sure that the HarmonicGuard filter is correct for the application. The voltage rating of the
filter must match the input voltage rating of the connected drive. The horsepower and current
ratings of the filter must be appropriate for the connected load.
HarmonicGuard Drive-Applied Filter
The HGP and HGL are drive-applied harmonic filters designed and developed by TCI to reduce
the harmonic currents drawn from the power source by VFDs with six-pulse diode bridge rectifier.
The published filter’s voltage, Power (HP or kW) and current ratings apply to matching power (Hp
or kW) rated standard VFDs with six-pulse diode bridge rectifiers. The harmonic filter may also
be sized to filter other loads such as SCR six-step drives, SCR Direct Current (DC) motor drives,
thyristor furnaces, battery chargers, electroplating supplies, or other types of nonlinear loads. In
many cases, the filter power rating (HP or kW) will differ from load power rating (HP or kW).
Please contact TCI Technical Support for additional information and support on sizing HGP
harmonic filters for your non-six-pulse diode front end VFD applications.
The HGP and HGL are passive filters connected in series with the input terminals of a VFD or
several VFDs that operate as a group. It is designed to provide a low impedance path for the
major harmonic currents demanded by the driver. The filter is a stand-alone device that can be
furnished in its own enclosure and mounted adjacent to the drive. It is also available on an open
panel for mounting within an enclosure with the drive or other equipment.
The HGP and HGL filters consist minimally of the following features and components:
•A KDR tuned series reactor to prevent system interaction and improve filter
performance.
•A tuned filter circuit with:
•A TCI three-phase tuning reactor specifically designed for the harmonic filter.
•High-endurance, harmonic-rated capacitors
•Larger filters may have multiple tuned circuits. Consult fuse tables to determine if
the filter in question has “parallel” branches.
•Bleeder resistors to ensure safe capacitor discharge upon filter shutdown.
•Cooling fans (on select models) to ensure adequate cooling and safe
operating temperatures.
•Compression terminals for ease and integrity of all power and control wiring
•Fuses - sized to protect the capacitor wiring.

HarmonicGuard Filter Manual 3.0 Pre-Installation Planning
HarmonicGuard Filter Overview
The HarmonicGuard®Passive Filter provides a low impedance path for the major harmonic
currents demanded by Variable Frequency Drives (VFDs). This greatly reduces the number of
harmonic currents flowing through the electrical power distribution system, bringing those
harmonic currents in line with the IEEE-519 standard for harmonic distortion mandated by an
increasing number of utilities.
The HarmonicGuard Filter includes branch fuses on the harmonic trap circuit capacitors. These
fuses are included in the design to prevent damage to the capacitors in the event of excessive
harmonic trap current if the filter is misapplied.
HarmonicGuard Options
Contactor Option (C)
This option includes a contactor, control power transformer and connection terminals in the filter
circuit which allows the VFD user to control the insertion of this circuit with a relay contact in the
VFD. It is recommended that the VFD contact be programmed to open the contactor below 33%
motor power. For variable torque (fan) loads this will be approximately below 70% speed, so at-
speed contact may be used. This reduces the possibility of leading power factor interacting with
other devices on the power system. Contactor logic should also maintain the contactor closed in
cases where the VFD is bypassed, and the filter is not bypassed. However, TCI recommends the
filter to be bypassed when the VFD is bypassed, to avoid low motor or VFD bypass voltage during
startup.
No Contactor Option (S)
This option includes high quality harmonic-grade capacitors and line reactors. This filter will meet
most application requirements found today. This cost-effective product is available as an open
panel version, in a UL Type 1 or UL Type 12 enclosure, or in an UL Type 3R enclosure. The open
panel is perfect for inclusion in an MCC section or easy installation into industry standard
enclosures. The UL Type 1 enclosed units maintain the same vertical profile as the open panel
design. This design is perfect for applications where floor space is at a premium. The UL Type
3R enclosure protects the filter from harsh conditions.
PQConnect w/ Modbus RTU Option (1)
This option includes a PQConnect board with Modbus RTU capability, control power transformer
and connection terminals in the filter circuit which allows the user to control the insertion of this
circuit with a relay contact in the VFD or PQVision Software. For an intelligent passive harmonic
that autonomously controls its tuning circuit contactor based on your input system to ensure worry
free operation. Allowing multiply forms of data capture to your SCADA system or directly to your
PLC. Field upgraded to EtherNet/IP option not available.
PQConnect w/ Modbus RTU & EtherNet/IP Option (2)
This option includes a PQConnect board with Modbus RTU and EtherNet/IP capability, control
power transformer and connection terminals in the filter circuit which allows the user to control
the insertion of this circuit with a relay contact in the VFD or PQVision Software. For an intelligent
passive harmonic that autonomously controls its tuning circuit contactor based on your input
system to ensure worry free operation, perfect for generator-based systems. The PQConnect with
Modbus RTU operation provides monitoring and status data to your SCADA system. EtherNet/IP
Protocol Conformance refer to EtherNet/IP section.

current harmonic distortion in applications with low background voltage distortion.
This performance option is available in all the package options.
High Voltage Distortion Option (1)
The High Voltage Distortion Option, intended for applications with levels of background voltage
distortion of 2% or higher, is a configuration that enables the HG filter to achieve lower levels of
current harmonic distortion in applications with high background voltage distortion.
This performance option is available in all the package options.
Heater Option (H)
The Heater Option is intended for use in applications which require the environmental protection
of a NEMA 3R enclosure. The heater is mounted to the interior of the enclosure and protects
sensitive electronic equipment from the harmful effects of corrosion and condensation.
The Heater option is available for all 3R enclosures. When using a Type 12 or Type 3R Enclosure
and in a high humidity environment, set thermostat to 37°C (100°F) or max temperature below 37°C
(100°F).
Vibration Pad Option (V)
The Vibration Pad Option is intended for use in applications which require environmental noise
protection. The resilient mounting material is placed between the reactor and the interior of the
enclosure and dampens noise produced by the reactor.
The Vibration Pad option is available for all enclosure types.
Oilfield Duty Option (P)
The Oilfield Duty Option features components designed specifically for oil and gas field applications
to handle the additional electrical stress. Designed for cyclical loads these units will be available in
Type 3R enclosures and will be for use with HP ranges from 40 to 200.

Over-temperature/Thermal Switch (T)
This option includes an over-temperature switch installed on both the Line Reactor and the
Tuning Reactor. On each reactor, over-temperature switches are wired to a terminal block
separate from the power terminals. The over-temperature switch opens if unpredicted heating
occurs. An interlocking circuit should be used with the over-temperature switch to turn off the VFD
to prevent filter damage in the event of filter overheating. The over-temperature switch contact is
rated 6 amps at 120 VAC. The over-temperature switches are normally closed, open on
temperature rise and typically have the following trip points:
•On a Class R 220°C insulation reactor, the switch opens on rise above 200°C
•On a Class H 180°C insulation reactor, the switch opens on rise above 160°C
Wire the over-temperature switches according to the reactor schematic using T1 and T2 locations
on the over-temperature switch terminal block.
Figure 2: Terminal Block
If this option is ordered with the PQconnect, the Thermal switch feedback will be wired to the
PQconnect board, and the PQconnect will indicate whether there is an over-temperature problem.
The PQconnect fault relay (J10 header) can be used to be alerted when there is an Over-temp
issue as an additional measure. For further detail please refer to the pin out references in section

operation, and maintenance. Make sure that the installation conforms to all working space and
clearance requirements of the National Electrical Code (NEC) and/or any other applicable codes.
Provide enough unobstructed space to allow cooling air to flow through the unit. Keep the widest
or deepest portion of the unit enclosure having ventilation openings a minimum of six inches from
adjacent walls or other equipment. The unit enclosure sides that do not have ventilation openings
should be kept a minimum of three inches from adjacent walls or other equipment.

HarmonicGuard Filter Manual 4.0 Installation Guidelines
Mounting
The harmonic filter must be mounted vertically on a smooth, solid surface, free from heat,
dampness, and condensation.
If you are mounting an open panel unit in your own enclosure, you must provide an enclosure
that is adequately sized and ventilated sufficiently to prevent overheating. The rating and
dimension tables for open panel units list the watts of heat loss dissipated by the harmonic filter.
The maximum temperature of the air around the harmonic filter’s capacitors, line reactor, and
tuning reactor should not exceed 50°C (122°F).
Wiring
When selecting a mounting location for the harmonic filter, plan for the routing of the power wiring.
Route the conduit and wiring from the power source to the filter and then to the VFD. The harmonic
filter is provided with internal fuses.
Cable Entry Locations
The enclosed harmonic filters are not provided with enclosure wiring knockouts. A location can
be selected at the time of installation. Typical or recommended cable entry locations are shown
on the drawings which can be found on the TCI website.

Field Wiring Connection Terminals
Compression type terminals (Lug Options) are provided for all field wiring connections. The wire
size capacity ranges and tightening torque for all field wiring connections are listed in Table 2-
Table 4.
Grounding
The HarmonicGuard filter panel equipment-grounding lug must be connected to the ground of the
wiring system. The equipment-grounding connection must conform to the requirements of the
National Electrical Code (NEC) and/or any other codes that apply to the installation site. The
ground connection must be made using a wire conductor. Metallic conduit is not a suitable
grounding conductor. The integrity of all ground connections should be periodically checked.
Caution
Use copper wire that is appropriate for the voltage and current rating of the
equipment. The wire selection must conform to the requirements of the National
Electrical Code (NEC) and/or other applicable electrical codes.
For units rated less than 100 amps, use wire with an insulation temperature rating
of 60°C or higher.
For units rated 100 amps or more, use wire with an insulation temperature rating
of 75°C or higher.
Connect the three-phase power of the appropriate voltage and current capacity to the circuit
protective device to the filter’s input power terminals.
Note: In large HP filters, the input and output power conductors are connected directly to the input
and output terminals on the line reactor.
Connect the output terminals of the filter to the input power terminals of the VFD.

Filter’s Schematic
Inspect the installation to make sure that all equipment has been completely and correctly installed
in accordance with the Installation Guidelines section of this manual.
•Check to see that the cooling fan(s) are operating in units so equipped.
•Check to make sure power connections are torqued to recommended torque value.
Since all HG products are passive filters, it is always operating whenever the drive is operating.
The Schematic shown below is an illustration of typical HG filter wiring.
Figure 3: Typical HarmonicGuard (HG) Filter Wiring for up to 480 V/800 HP
Always refer to the drawings and other information shipped with your unit. Consult applicable wiring
codes, UL, and NEC, for current limiting and disconnect requirements.
Warning
Exercise caution when connecting the filter to the VFD. Internal filter components
may carry dangerous voltage which can cause death or serious injury upon
contact. Remove all power to the HarmonicGuard filter in compliance to
standardized 26 CFR 1920.147 lockout/tagout policies.
