IMPORTANT USER INFORMATION
NOTICE
The MTE Corporation Matrix Filter is designed for harmonic mitigation of six
pulse inverter drives supplying variable torque loads in a wide variety of
applications. The suitability of this filter for a specific application must
therefore be determined by the customer. In no event will MTE Corporation
assume responsibility or liability for any direct or consequential damages
resulting from the use or application of this filter. Nor will MTE Corporation
assume patent liability with respect to the use of information, circuits or
equipment described in this instruction manual.

1. IMPORTANT SAFETY INFORMATION
WARNING
ONLY A QUALIFIED ELECTRICIAN CAN CARRY OUT THE ELECTRICAL
INSTALLATION OF THIS FILTER
WARNING
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.
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 1, 2 and 3 on terminal block
1TB. Start with the meter on the highest scale and progressively switch to a lower
scale as the indicated voltage falls below the maximum value of the scale used.
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.
WARNING
An upstream disconnect/protection device must be used as required by the National
Electrical Code (NEC).
WARNING
Even if the upstream disconnect/protection device is open, the drive down stream of the filter
may feed back high voltage to the filter. The drive safety instructions must be followed.
INJURY OR DEATH MAY RESULT IF THE DRIVE SAFETY PRECAUTIONS ARE
NOT OBSERVED.

WARNING
The filter must be grounded with a grounding conductor connected to all grounding terminals.
WARNING
Only spare parts obtained from MTE Corporation or an authorized MTE distributor can be
used.

2. INTRODUCTION
This manual was specifically developed to
assist in the installation, interconnection
and operation of the MTE Corporation
Matrix Filter.
This manual is intended for use by
personnel experienced in the operation and
maintenance of electronic drives. Because
of the high voltages required by the filter
and 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 the drive to which the filter is
connected.
Upon Receipt of this Filter:
The MTE Matrix 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 has accumulated on the
internal components of the filter before
applying power.
Repair/Exchange Procedure
MTE Corporation requires a Returned
Material Authorization Number before it can
accept any filters that qualify for return or
repair. If problems or questions arise during
installation, setup, or operation of the filter,
please call us for assistance at:
Phone: 262-253-8200
FAX: 262-253-8222
