General Safety Instructions
WARNING
High Voltage! 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.
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) or governing authority.
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 safety
precautions are not observed.
WARNING
The filter must be grounded with a grounding conductor connected to all
grounding terminals. Modular filters must have reactor grounded througha
2”x2” area cleaned of paint and varnish on lower mounting bracket.
WARNING
Only spare parts obtained from MTE Corporation or an authorized MTE
distributor can be used.
WARNING
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.
Caution
Prior to start up; confirm the drive operation mode is property set (Volts per
Hertz). Please consult drive manual/manufacturer to configure proper
parameters. Failure to do so may result in failure of drive or filter
components.

2. INTRODUCTION
The purpose of the manual is to properly specify, size, and install the SineWave Guardian.
For most current information, please refer to website
http://www.mtecorp.com/products/sinewave-guardian/
SineWave Guardian Filters transform the output of Variable Frequency Drives (VFDs) to a near
perfect sinusoidal waveform for the best level of motor protection. MTE’s unique, patent-pending
design offers high performance with smaller size and better efficiency than traditional LC Filters.

3. HOW TO SELECT
Selection Guide
MTE SineWave Guardian Motor Protection Filters are designed to provide a sine wave output
voltage when driven from PWM inverters with switching frequencies from 2 kHz to 8 kHz. For
drive applications, these filters eliminate the problem of motor insulation failures and they also
reduce electromagnetic interference by eliminating the high dV/dt associated with inverter
output wave forms.
SineWave Guardian Motor Protection Filters are available in Modular, NEMA 1/2, and 3R
mechanical configurations.
For inverters feeding isolation transformers select a filter with a current rating equal to or greater
than that of the transformer primary current.
Please verify information below for proper selection:
Voltage: Input voltage from 380V – 480V. See Table 4-1 (p11) for specification.
Current Rating: Support for 2 Amps – 720 Amps. See Table 4-1 (p11) for Amp breaks.
Switching Frequency: Support for carrier frequency of 2kHz – 8kHz, see Table 4-1
(p11).
Drive Output Frequency: Support for 6Hz to 75Hz without derating, >75Hz to 120Hz
with derating. See Figure 5-4 (p15) for derating curve.
Temperature: Maximum ambient temperature, 60C (modular), 55C (enclosed). See
Table 4-1 (p11) for specification.
Altitude: 3,300 feet above sea level without derating. See Figure 5-3 (p15) for derating
curve.
Enclosure Type: Modular, NEMA 1/2 & NEMA 3R, see Enclosures (p12) for
enclosure descriptions.
Verify the drive output can be configured to Volts per Hz mode.

6. HOW TO INSTALL
Installation Checklist
WARNING
Prior to installation, please refer to all general warnings on page 4.
Failure to practice this can result in body injury!
WARNING
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.
Verify that the rating of the filter is compatible with the drive to which it is to be connected. Follow
all detailed drive manufacturer installation and safety instructions. Drive and load cable selection /
placement should be in accordance with the requirements of the NEC and all local electrical
codes and regulations
The typical interconnection diagrams that follow are shown for a motor load but the load can
be either a motor or a transformer.
For modular filters interconnection between the filter, motor and the drive is shown in
Figure 6-1 (p18).
 For filters supplied in general purpose NEMA1/2 and 3R cabinets, interconnection
between the filter, motor and the drive is shown in Figure 6-2 (p19).
Refer to the drive user manual for instructions on interconnecting the drive and motor and the
correct start-up procedures for the drive. Do not use auto-tune with filter.
Table 6-1 (p22) lists the wire range and terminaltorque requirements forthe power input and
output connections and capacitor/capacitor panel connections (modular only).
Use the cable recommended by the drive manufacturer to connect the drive to the filter and
the filter to the motor. Make certain that the selected cable size conforms to the requirements of
the National Electric Code and all local codes.

Grounding
For cable shield grounding followthe drive manufactures recommendations.
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 4-2 (p12) for contact rating information and the drive user manual for
interconnection information.
Location & Spacing
Modular filters are designed for mounting in the customer’s enclosure. Include the power
dissipation of the filter along with all the other components located in the panel to determine
the internal temperature rise and cooling requirements of 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 within the enclosure. Clearances maybe less if proper ventilation
exists. Filter components must operate within temperatures specified in this manual or filter
operating life will be compromised. Also be aware of minimum electrical clearances as defined by
the appropriate system safety standard(s). Modular SineWave filters generate heat and should be
positioned away from heat sensitive components. Ensure that proper panel orientation is
maintained. Keep the capacitors away from reactor and resistor heat flow. Avoid locations
where the filter would be subjected to excessive vibrations. Locate the filteras close to the
inverter as possible.
General purpose NEMA 1, 2 and 3R enclosed filters are designed for floor mounting in an
environment suitable for the enclosure type. Do not install in or near a corrosive environment.
Avoid locations where the filter would be subjected to excessive vibrations. Allow a minimum
side and back clearance of eight (8) inches for proper ventilation. Also consider spacing required
for accessibility. Locate the filter as close to the inverter as possible.
Mechanical Mounting
Please refer to Part Number Selection Tables for mounting locations.
Modular: Table 3-1 (p8)
Enclosed NEMA 1/2: Table 3-2 (p9)
Enclosed NEMA 3R: Table 3-3 (p10)
WARNING
The filter must always be grounded with a grounding conductor
connected to ground terminals.
WARNING
For modular units, ensure a 2” X 2” area is cleaned of paint
and varnish on lower mounting bracket for ground connection.
