IMPORTANT USER INFORMATION

NOTICE

MTE Series RLW reactors are components designed to improve the reliability of three or
single phase AC adjustable frequency drives, DC drives and a wide variety of other types
of power electronic equipment. In addition they provide input line current harmonic
mitigation and 100 foot long lead protection for inverter fed motors. MTE reactors are
available in a large number of current ratings and a variety of inductance values. The
suitability of a 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 or
equipment described in this instruction manual.

IMPORTANT SAFETY INFORMATION WARNING

ONLY A QUALIFIED ELECTRICIAN CAN CARRY OUT

THE ELECTRICAL INSTALLATION OF LINE/LOAD

REACTORS

WARNING

High voltage is used in the operation of line/load reactors. Use Extreme caution to
avoid contact with high voltage when operating, installing or repairing equipment
containing line/load reactors.

INJURY OR DEATH MAY RESULT IF SAFETY PRECAUTIONS ARE

NOT OBSERVED.

Line/load reactors are used in conjunction with inverters, or other electrical
equipment that may feedback lethal voltages. Follow the safety instructions in
the equipment used with the reactor in addition to the safety instruction in 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.

IMPORTANT SAFETY INFORMATION WARNING, CONT.

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
downstream of the line/load reactor may feedback 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.

WARNING

The frame of line/load reactors must be grounded at least at one of the
reactor’s mounting holes.

WARNING

Only spare parts obtained from MTE Corporation or an authorized MTE
distributor can be used

INTRODUCTION

This manual was specifically developed to assist in the installation, interconnection and operation of
MTE Corporation Series RLW 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:

Reactor Installation

MTE world reactors are available in open construction and in NEMA 1 and NEMA 3R enclosures.
Open reactors are designed for mounting within an appropriate electrical equipment enclosure.
Reactors rated 300 amperes RMS and under are designed for mounting in both a vertical and
horizontal position. Larger reactors must be mounted in a horizontal position typically on the floor of the
enclosure. Include the power dissipation of the reactor along with all the other components located in the
enclosure to determine the internal temperature rise and cooling requirements of the enclosure.

Reactors may be located in any region of the enclosure where the ambient temperature does not exceed
45 degrees C. Allow a minimum side clearances of four (4) inches and vertical clearances of six (6) inches
for proper heat dissipation and access. Do not locate the reactor next to resistors or any other component
with operating surface temperatures above 125 degree C.

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 reactor will be subjected to excessive vibrations.

NEMA 1 and NEMA 3R Enclosed world Reactor Installation

MTE RLW reactors mounted in enclosures with part number, CAB-8, are designed for wall mounting.
All other enclosures are designed for floor mounting and only RLW reactors 200 Amps and higher are
available in a NEMA 3R enclosure.

WARNING

MTE NEMA 1 and NEMA 3R enclosures designed for floor mounting must be mounted with the
enclosure base horizontal for proper ventilation. Wall mounting a floor mounted enclosure with
the base against the wall will cause the reactor to overheat resulting in equip ment d amage.

Allow a minimum side, front, and back clearances of twelve (12) inches and vertical clearances of
eighteen (18) inches for proper heat dissipation and access. Do not locate the enclosure next to resistors
or any other component with operating surface temperatures above 125 degree C.

Select a well-ventilated, dust-free area away from direct sunlight, rain or moisture where the ambient
temperature does not exceed 40 degrees C.

Do not install in or near a corrosive environment.

Avoid locations where the reactor will be subjected to excessive vibrations.

Where desirable, reactors or enclosures may be mounted on vibration isolating pads to reduce audible
noise. Standard vibration control pads made from neoprene or natural rubber and selected for the
weight of the enclosed reactor are effective.

Power Wiring Connection

WARNING

Input and output power wiring to the reactor should be performed by authorized
personnel in accordance with the NEC and all local electrical codes and
regulations.

Verify that the power source to which the reactor is to be connected is in agreement with the nameplate
data on the reactor. A fused disconnect switch or circuit breaker should be installed between the reactor
and its source of power in accordance with the requirements of the NEC and all local electrical codes and
regulations. Refer to the drive, inverter, or other electrical equipment user manual for selection of the correct
fuse rating and class.

The reactor is suitable for use on a circuit capable of delivering not more than 65,000 rms symmetrical
amperes at 480 volts when protected by Bussman type JJS, KTK, KTK-R, SPP or T class fuses.

Reactors are designed for use with copper conductors with a minimum temperature rating of 75
degrees C. Table 2 lists the wire range and terminal torque requirements for the power input and output
connections by reactor part number.

Refer to Figure 7 for typical electrical diagrams describing the application of reactors in both line and
load applications. For reactors supplied as a component part of a drive system or a component part of
power electronic apparatus follow the interconnection diagram supplied by the System Engineer.

Where desirable, a flexible conduit connection to the reactor enclosure should be made to reduce
audible noise.

WARNING

Failure to connect reactors supplied as a component part of a drive system or other power
electronic system according to the sy stem interconnection diagram supplied by t he Syst em
Engineer will result in equipment damage, injury, or death.

WARNING

If a line reactor or a line reactor and a load reactor are used with a drive equipped with a bypass
circuit, the reactors must be removed from the motor circuit in the bypass mode. Damage to the
motor and other equipment will result if this warning is not observed.
