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 down
stream 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 sever 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.

Grounding
Cable Shield Grounding
For cable shield grounding follow the drive manufactures recommendations.
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 Interlock
An over temperature 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 3-1 below for contact rating information and the drive user manual for
interconnection information.

Harmonic Filter Field Checks
1. Read and understand the Matrix APAX Technical Reference Manual which can be
downloaded at www.mtecorp.com/matrix-apax-literature-documents/. Locate figures and
drawings for your particular filter and identify the terminal locations.
2. Disconnect all power and remove input power wiring from U1, V1, and W1 terminals.
3. Remove VFD drive power connections from filter terminals U2, V2, and W2 as well as
any control wiring to the filter contactor or temperature switch. (For filters using control
transformers: remove power fuses on top of transformer.)
4. Visually inspect filter terminals and wiring lugs for signs of heat and corrosion. Contact
factory if any wires appear to be missing or cut!
5. Inspect the U4, V4, and W4 capacitor interconnect terminals and wiring.
6. Visually inspect all capacitors for signs of case deformation, bowing of the top, leaking
oil or terminal damage. Note the CAP- # and date code of any damaged capacitors.
7. Using a multi meter set to read 100K ohms check:
a. Phase to phase U1-V1-W1-U1 (mechanically activate contactor if present) after
reactor and caps charge reading should be about 40K (total equivalent breeder
resistance value). Open circuit or very low readings indicate a problem.
b. Phase to chassis U1- case, V1-case, and W1-case; low readings indicate a
ground fault problem.
8. Ensure the “disconnect” is safe then wire the utility power to U1, V1, and W1.
9. Apply power and verify that proper output voltage is present on U2, V2, and W2.
10. Using a clamp on amp meter read the filter input current:
a. Readings will be 0.4 of the capacitor current listed in the Matrix APAX Technical
Reference Manual found at www.mtecorp.com/matrix-apax-literature-
documents/. Mechanically activate the contactor if the filter is equipped with one.
Readings should be the same (+/- 5%) for all phase currents; contact the
factory if currents are out of tolerance!
b. Open contactor readings will show zero current for all phases.
11. Disconnect filter power and wire the VFD to U2, V2, and W2 as well as any control
wiring to the filter contactor or temperature switch. Replace any control transformer
fuses. Follow the drive power startup guidelines in the drive manufacturer’s user manual.
