INSTALLATION INSTRUCTIONS
Filter Installation
Matrix Filter® are supplied in the following
mechanical configurations:
Panel mounted assemblies
Floor mounted general purpose NEMA 2,
& 3R cabinets,
Select a well ventilated, dust-free area away
from direct sunlight, rain or moisture. Do not
install in or near a corrosive environment.
Avoid locations where the filter would be
subjected to excessive vibrations.
Panel mounted filters are designed for
mounting in the vertical plane within the
customer’s enclosure. Panel mount units are
made up of a Harmonic Mitigating Reactor
(HMR) and one or more capacitor panel
assemblies referred to as cappanels on
drawings and diagrams.
The capacitor assembly should be located in
the lowest temperature regions of the
enclosure - generally toward the bottom and
away from high temperature components.
Mount the Harmonic Mitigating Reactor in a
location where the ambient temperature does
not exceed 50 degrees C. Allow a minimum
side clearance of four (4) inches and a
vertical clearance of six (6) inches for proper
heat dissipation and access.
Figure 5 - 18 contain outline drawings for the
various ratings and show mounting orientation
with bolt patterns.
Include the power dissipation of the filter
along with all the other components located in
the enclosure to determine the internal
temperature rise and cooling requirements of
the enclosure.
General purpose NEMA 2, and 3R enclosed
filters are designed for floor mounting in the
vertical plane in an environment suitable for
the enclosure type. Do not install in or near a
corrosive environment. Avoid locations where
the filter would be subjected to excessive
vibrations. Allow a minimum side and back
clearance of eight (8) inches and front
clearance of thirty-six (36) inches for proper
heat dissipation and access.
Refer to Article 430 Table 430.91 of the
National Electrical code for the selection of
the appropriate enclosure Type Number for
your application.

RK1 class fuses or a circuit breaker having
a interrupting rating not less than 100K
RMS symmetrical amperes, 480 volts
maximum.
For panel mounted filter applications
interconnection between the filter, its power
source the cappanels and the drive is
shown in Figure 19. Table 10 lists the wire
range and terminal torque requirements as
a function of filter current ratings. Use table
10 for selecting conductors that interconnect
the HMR and capacitor assemblies. Filters
that use multiple cappanels share total cap
current shown on table 3.
Refer to the drive user manual for
instructions on interconnecting the drive and
motor and the correct start-up procedures
for the drive.
The filter is designed for use with copper
conductors with a minimum temperature
rating of 75 degrees C.
For filters supplied in general purpose
NEMA, 2 & 3R cabinets, interconnection
between the filter, its power source, and the
drive is shown in Figure 20. Refer to Figures
14 to 18 for the location of input, output, and
ground and over temperature switch
terminals. Table 10 lists the wire range and
terminal torque requirements as a function
of filter current ratings. Refer to the drive
user manual for instructions on
interconnecting the drive and motor and the
correct start-up procedures for the drive.
Grounding and Ground Fault Protection
The filter must always be grounded with a
grounding conductor connected to all
ground terminals.
Due to high leakage currents associated
with variable frequency drives, ground fault
protective devices do not necessarily
operate correctly when placed ahead of a
Matrix Filter® feeding a drive. When using
this type of device, its function should be
tested in the actual installation.
Over Temperature Switch
The temperature switch is provided to
annunciate adverse filter heating. Damage
to the filter or drive may be avoided by
interlocking this switch to shutdown the
drive or illuminate a service light; see
figures 19 and 20 for connection diagrams.
Read the vendor drive manual for details in
using interlock inputs.

FILTER DESCRIPTION
The MTE Matrix Filter® is a low pass filter
containing proprietary technology, which
makes it particularly useful for harmonic
mitigation of adjustable speed drives. Figure
20 shows a block diagram of the filter.
Three phase AC power is connected to the
Harmonic Mitigating reactor HMR section
which contains patented circuitry which
inhibits oscillation of the filter with the AC
power system. Shunt resistors and
capacitor panels make up the rest of the
filter. Because of the capacitor bank the
filter operates with leading power factor at
light loads, but unlike trap filters the MTE
Matrix Filter® does not produce significant
voltage rise at the point of common coupling
with the power system.
The Matrix Filter® is suitable for use with
AC and DC drives and they can be used in
both regenerative and non-regenerative
applications when properly selected. For AC
regenerative drives application consult the
factory.
Filters for variable torque AC drives rated
7.5 Hp and above should be selected for a
filter output current rating greater than or
equal to the motor current rating. If the
motor current rating is not available, use the
NEC motor current rating.
Filters for variable torque AC drives rated 2
– 5 Hp should be selected for a filter output
current rating greater than or equal to 105%
of the motor current rating. If the motor
current rating is not available, select on the
basis of 105% of the NEC motor current
rating.
Filters for variable torque AC drives rated
less than 1.5 Hp should be selected for an
output current rating greater than or equal to
110% of the motor current rating or 110%
OF the NEC motor current rating.
For constant torque, AC and DC drive
applications operating from six pulse
rectifier front ends selected a filter current
rating according to application engineering
note “Matrix Filter® Operation in Constant
Torque Applications with Six Pulse
Rectifiers” or consult MTE engineering. For
phase controlled DC drive applications,
select filter current rating per application
note “Matrix Filter® with Phase Controlled
DC Drivers.
Where a single filter is used to feed multiple
drives, the output current rating of the filter
should be selected to equal the total current
rating of the individual drives when
calculated according to the instructions
above.
Because the filter supplies harmonic
currents required by the drive, linear loads
(such as space heaters, incandescent
lighting and AC motors operated across the
line) should not be connected to the output
of the filter
.

Warning!!!
Equipment damage may result from activation of the bypass contactor during motor operation.
Ensure the motor is at rest before switching the bypass control contactor!
Purpose: Provide compatible hardware to integrate a system motor bypass when used in conjunction with
a drive which supports the bypass function as required for HVAC and control applications.
1.) To switch out the Matrix Filter® and connect utility power to the Matrix output terminals to
support a motor bypass initiated from the control contact of the drive.
2.) During the bypass mode, remove the effect of Matrix Filter® capacitor loading on drive utility
branch circuits
Design:
For low current Matrix Filter® s a single contactor CR1 provides the dual function switching to
accomplish bypassing the Matrix Filter® and removal of the filter’s capacitors. For higher current filters a
second powered contactor CR2 connects the capacitors to the filter circuit. See the schematic drawings
that shows these circuits.
Function description:
1.) (Matrix Filter® mode): The bypass coil CR1 is de-energized: the Matrix Filter® provides normal
harmonic attenuation of the VFD distorted power. For the dual contactor systems the capacitor
contactor CR2 must be powered to get maximum THID reduction.
2.) With 120 Vac 50 Hz on CR1 from the customer supplied contact selection:
A three phase connection is made across the Matrix Filter® input to the corresponding output
terminals. At the same time CR1 auxiliary contacts or the second CR2 contactor remove the
capacitors from the filter circuit.
