1. SAFETY
Warnings and Cautions
The following symbols are used in this manual.
Product Safety Labeling
The following labels are placed on the Matrix E-Series product:
WARNING
High Voltage Warning: warns of situations that dangerously
high voltage is involved. Failure to use proper precautions may
lead to serious injury or death.
WARNING
General Warning: warns of situations that can result in serious
injury or death if proper precautions are not used.
Caution
General Caution: identifies situations that could lead to
malfunction or possible equipment damage.
Label notes to installer to refer to instruction manual first before
installing.
High Voltage: surfaces on product can have high voltage which
can cause injury.
Wait five minutes for capacitors to discharge. Verify safe
voltage level before servicing.
Connect Thermal Switch: connecting the thermal switch can
reduce risk of damage.

General Safety Instructions
WARNING
High Voltage! Only a qualified electrician can carry out the electrical
installation of this filter.
High voltage is used in the operation of this filter. Use Extreme caution to avoid
contact with high voltage when operating, installing or repairing this filter.
Injury or death may result if safety precautions are not observed.
WARNING
The opening of the branch circuit protective device may be an indication that a
fault current has been interrupted. To reduce the risk of fire or electrical shock,
current-carrying parts and other components of the filter should be examined
and replaced if damaged.
An upstream disconnect/protection device must be used as required by the
National Electrical Code (NEC) or governing authority.
Even if the upstream disconnect/protection device is open, the drive
downstream of the filter may feedback high voltage to the filter. The drive
safety instructions must be followed. Injury or death may result if safety
precautions are not observed.
The filter must be grounded with a grounding conductor connected to all
grounding terminals.
Only spare parts obtained from MTE Corporation or an authorized MTE
distributor can be used.
After removing power, allow at least five minutes to elapse and verify that the
capacitors have discharged to a safe level before contacting internal
components. Connect a DC voltmeter across the capacitor terminals and ensure
that the voltage is at a safe level.
Caution
Loose or improperly secured connections may damage or degrade filter
performance. Visually inspect and secure all electrical connections before
power is applied to the filter.
Product should not be mounted on wood or any other combustible surface.
Doing so could lead to fire or damage to the product.
The user of this filter must assure that the input voltage and frequency is
correct for the filter rating and that the voltage applied falls within the rated
operating tolerance envelop specified for the filter. For severe power line
applications where the power feed is likely to experience surges and transients
that exceed the input voltage rating, it is recommended that a TVSS (Transient
Voltage Surge Suppression) or SPD (Surge Protection Device) be deployed
ahead of the filter to reduce the possibility of exceeding the filter rated voltage.
Consult with TVSS or SPD manufacturer to determine the correct protection for
your power line conditions.
Filter must be mounted in the proper orientation per labeling.

2. GENERAL INFORMATION
The purpose of this manual is to aid in the proper installation of the Matrix® E-Series.
For most current product information, please refer to our website:
www.mtecorp.com/products/harmonic-filters/matrix-e-series-harmonic-filter/
This manual is intended for use by personnel experienced in the operation and maintenance of drives.
Because of the high voltages required by the filter, drive and the potential dangers presented by
rotating machinery, it is essential that all personnel involved in the operation and maintenance of this
filter know and practice the necessary safety precautions for this type of equipment. Personnel should
read and understand the instructions contained in this manual before installing, operating or servicing
the filter and drive to which it is connected.
Receipt & Repair Statement
Upon Receipt of this Filter:
The Matrix E-Series Harmonic Filter has been subjected to demanding factory tests before shipment.
Carefully inspect the shipping container for damage that may have occurred in transit. Then unpack the
filter and carefully inspect for any signs of damage. Save the shipping container for future transport of
the filter.
In the event of damage, please contact and file a claim with the freight carrier involved
immediately.
If the equipment is not going to be put into service upon receipt, cover and store the filter in a clean, dry
location. After storage, ensure that the equipment is dry, and that no condensation or dirt has
accumulated on the internal components of the filter before applying power.
Repair/Exchange Procedure
MTE Corporation requires a Return Material Authorization Number and form before we can accept any
filters that qualify for return or repair. If problems or questions arise during installation, setup, or
operation of the filter, please contact MTE for assistance at:

This plot assists in proper de-rating of a Matrix E-Series harmonic filter in environments with a
preexisting voltage distortion. Example: In a system with 10% voltage distortion, a Matrix filter
will need to be oversized by 5.5% to obtain the same performance as an appropriate filter in a
0% distortion environment.

5. HOW TO INSTALL
Installation Checklist
WARNING
Prior to installation, please refer to all general warnings on pages 1 & 2. Failure
to practice this can result in bodily injury!
Input and output wiring to the filter should be performed by authorized personnel
in accordance with NEC and all local electrical codes and regulations.
WARNING
The filter is designed for use with copper conductors with a minimum
temperature rating of 75 degrees C.
CAUTION
FAN COOLING
For units 21 Amps and above: Proper cooling airflow must be provided at
a minimum of 400 linear feet/min.
Matrix E-Series filters are supplied in the following configuration(s):
•Open Panel (Modular): Open panel units consist of a reactor and one or more capacitors.
Additional wiring between the reactor and capacitor is required by the customer.
Open panel Matrix E-Series filters are designed for mounting within the customer’s enclosure. When
determining the internal temperature rise and cooling requirements of the enclosure, include the power
dissipation of the filter along with all the other components located in the enclosure. A general guideline
is to allow a side clearance of four (4) inches and a vertical clearance of six (6) inches for proper heat
dissipation and access with the enclosure.
For units 21 Amps and above, proper cooling airflow must be provided at a minimum of 400
linear feet/min.
Do not install in or near a corrosive environment.
Avoid locations where the filter would be subjected to excessive vibrations.
Locate the filter in the lowest temperature regions of the enclosure – generally toward the bottom and
away from high temperature components.
Refer to Article 430 Table 430.91 of the National Electrical code for the selection of the appropriate
enclosure Type Number for your application.

Grounding
NOTE: For cable shield grounding follow the drive manufacturer’s recommendations.
Grounding and Ground Fault Protection
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.
Overtemperature Interlock
An overtemperature interlock circuit should be used in conjunction with thermal switch to turn off the
drive to prevent filter damage due to abnormal operating conditions.
The temperature switch is normally
closed and will open when an internal reactor temperature of 180°C is reached.
See Table 5-1:
Overtemperature Switch

interconnection information.

MTE highly recommends the use of the overtemperature switch to prevent damage to the filter in rare
instances of overheating from abnormal operating conditions.
WARNING
The filter must always be grounded with a grounding conductor connected to
ground terminals.
