Important User Information
NOTICE
MTE Series RL Line/Load Reactors are components designed to improve the reliability of
adjustable frequency drives, DC drives and a wide variety of other types of power
electronic equipment. In addition, they provide limited input line current harmonic
mitigation and aid in long lead protection for inverter fed motors. Note: (See MTE
harmonic filters and motor protection products for guaranteed results.) MTE reactors are
available in a large number of current ratings and a variety of inductance values. The
suitability of a line/load reactor for a specific application must therefore be ultimately
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
reactors. Nor will MTE Corporation assume patent liability with respect to the use of
information, circuits orequipmentdescribedinthisinstructionmanual.
This manual includes recently redesigned performance enhanced reactors. These reactors are
physically smaller and weigh less than the reactors they replace. Enhanced reactors have base
mounting brackets with additional slotted holes to accommodate past mounting hole centers. You
may use your existing drill pattern or choose the new layout. The tables contained in this manual

WARNING
Highvoltageis used intheoperation of line/loadreactors. Use Extreme caution to avoid contact with high
voltagewhenoperating,installingor repairing equipment containing line/load reactors
INJURYORDEATHMAYRESULTIFSAFETYPRECAUTIONSARE NOT OBSERVED.
Line/loadreactorsareused inconjunctionwithinverters,or other electrical equipment thatmayfeedback
lethal voltages. Follow the safety instructions in the equipment used with the reactor in addition to the
safetyinstructionin this manual.
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, line/load reactors 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, a drive or inverter down stream of the
line/load reactor may feed back high voltage to the reactor. The inverter or drive safety instructions
must be followed.
INJURY OR DEATH MAY RESULT IF THE DRIVE SAFETY PRECAUTIONS ARE NOT
OBSERVED.

INTRODUCTION
This manual was specifically developed to
assist in the installation, interconnection and
operation of MTE Corporation Series RL
Line/Load Reactors
This manual is intended for use by
personnel experienced in the operation and
maintenance of electronic drives, inverters
and similar types of power electronic
equipment. Because of the high voltages
required by the equipment connected to
line/load reactors and the potential dangers
presented by rotating machinery, it is
essential that all personnel involved in the
operation and maintenance of line/load
reactors 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 line/load reactors and the drive to
which the reactor is connected.
Upon Receipt of a Reactor:
MTE Line/load Reactors have 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 reactor.
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
reactor in a clean, dry location. After
storage, ensure that the equipment is dry
and that no condensation has accumulated
on the reactor before applying power.
Repair/Exchange Procedure
MTE Corporation requires a Returned
Material Authorization Number before it can
accept any reactors 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:
