installation of this filter.
High voltage is used in the operation of this filter. Use extreme caution to
observed.
General Safety Instructions
WARNING
WARNING
avoid contact with high voltage when operating, installing or repairing this
Injury or death may result if safety precautions are not
filter.
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
downstream 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.
The filter must be grounded with a grounding conductor connected to all
grounding terminals. Modular filters must have reactor grounded through
a 2”x2” area cleaned of paint and varnish on lower mounting bracket.
Only spare parts obtained from MTE Corporation or an authorized MTE
distributor can be used.
Caution
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.
Review the schematic prior to connecting unit in DC Bus Configuration.
Connecting the unit incorrectly could result in failure of drive and filter
components.
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.
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.

SineWave Nexus™ Installation Guide 380V – 600V
2. GENERAL INFORMATION
The purpose of the manual is to aid in the proper installation of the SineWave Nexus.
For most current information, please refer to website:
http://www.mtecorp.com/nexus-sinewave-filter/
SineWave Nexus 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 design offers
high performance in both differential and common mode with smaller size and better efficiency
than traditional industry solutions.
Receipt & Repair Statement
Upon Receipt of this Filter:
The SineWave Nexus motor protection 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 or
dirt has accumulated on the internal components of the filter before applying power.
Warranty
Three years from the date of shipment. See http://www.mtecorp.com/industry-leading-warranty/
for details.

WARNING
3. HOW TO INSTALL
Installation Checklist
Prior to installation, please review the safety instructions on page 4 & 5.
Failure to practice this can result in body injury!
WARNING
SineWave Nexus filters are supplied in the following mechanical configurations:
• Modular: Modular units consist of a reactor, a common mode assembly and one or more
capacitor or capacitor panel assemblies (referred to as cap-panels on drawings and
diagrams). Additional wiring between the reactor, common mode assembly and
capacitor/capacitor panel assembly is required by customer.
• Floor mounted general purpose NEMA 1/2 and NEMA 3R cabinets: Reactor, common mode
assembly and capacitor/capacitor panel assemblies are supplied in a cabinet with all items
pre-wired together.
Minimum Required Space:
Open panel SineWave Nexus filters are designed for mounting within the customer’s enclosure.
When determining the internal temperature rise and cooling requirements of the enclosure,
include the power dissipation of the filter along with all the other components located in the panel.
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 may be 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 Nexus
filters generate heat and should be positioned away from heat sensitive components. Avoid
locations where the filter would be subjected to excessive vibrations. Locate the filter as close to
the inverter as possible.
NOTE: Locate the capacitor(s) and common mode assembly in the lowest temperature
regions of the enclosure – generally toward the bottom and away from high temperature
components.
General purpose NEMA 1/2 and NEMA 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 and front clearance of thirty-six (36) inches for proper heat
dissipation and access.
Input and output wiring to the filter should be performed by authorized
personnel in accordance with NEC and all local electrical codes and
regulations.
The filter is designed for use with copper conductors with a minimum
temperature rating of 75 degrees C.

Grounding
The filter must always be grounded with a grounding conductor connected to ground
terminals.
WARNING
NOTE: For cable shield grounding follow the drive manufacturer’s recommendations.
Grounding and Ground Fault Protection
Due to high leakage currents associated with variable frequency drives, ground fault protective
devices do not necessarily operate correctly. When using this type of device, its function should
be tested in the actual installation.
Overtemperature Interlock
An overtemperature 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: Overtemperature Switch, below for contact rating information and the drive user
manual for interconnection information.
For modular units, ensure a 2” X 2” area is cleaned of paint and varnish on lower
mounting bracket for ground connection.
Table 3-1: Overtemperature Switch
MTE highly recommends the use of the overtemperature switch to prevent damage to the filter
in rare instances of overheating from abnormal operating conditions.
