1. SAFETY
Warnings and Cautions
The following symbols are used in this manual:
WARNING
High Voltage Warning: warns of situations that dangerously
high voltage is involved. Failure to use proper precautions may
lead to serious injury or death.
WARNING
General Warning: warns of situations that can result in serious
injury or death if proper precautions are not used.
Caution
General Caution: identifies situations that could lead to
malfunction or possible equipment damage.

General Safety Instructions
WARNING
High Voltage! Only a qualified electrician can carry out the electrical
installation of this filter.
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.
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.
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.
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.
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. GENERAL INFORMATION
The purpose of this manual is to properly specify, size, and install 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.
Repair/Exchange Procedure
MTE Corporation requires a Return Material Authorization Number and form before we can accept
any filters that qualify for return or repair. If problems or questions arise during installation, setup, or
operation of the filter, please contact MTE for assistance at:

Enclosures
MTE enclosures are designed to provide a degree of protection for electrical components and
prevent incidental personnel contact with the enclosed equipment. Depending on the enclosure
selected, these enclosures meet the requirements of NEMA 1/2 or NEMA 3R.
An approximate cross reference guide between NEMA, UL, CSA and IEC enclosure follows.
Type 1 NEMA / IEC IP20 Enclosure:
Are designed for indoor use and will provide protection against contact with the enclosed
equipment.
Type 2 NEMA / IEC IP20 Enclosure:
Are designed for indoor use and will provide protection against contact with the enclosed
equipment and provide a degree of protection against limited amounts of falling water and
dirt.
Type 3R NEMA / IEC IP21 Enclosure:
Are designed for outdoor use primarily to provide protection against contact with the
enclosed equipment and provide a degree of protection against falling rain sleet and
external ice formation.
Agency Approvals
UL and cUL listed to UL508 Type MX and CSA-C22.2 No 14-95
File E180243
Warranty
Three years from the date of shipment. See http://www.mtecorp.com/industry-leading-warranty/ for
details.
