1. SAFETY
Warnings and Cautions
The following symbols are used in this manual:
Product Safety Labeling
The following labels are placed on the dV Sentry product:
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.
Label notes to installer to refer to instruction manual first before
installing.
High Voltage: surfaces on product can have high voltage which can
cause injury.
Connect Thermal Switch: connecting the thermal switch can reduce
risk of damage.
Hot Surfaces: surfaces of product can be hot at times and cause
burns.

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
down stream of the filter may feedback 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
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.
Wiring should not be routed underneath panel in resistor housing. Doing
so could result in fire or damage to the product.
Product should not be mounted on wood or any other combustible
surface. Doing so could lead to fire or damage to the product.

2. GENERAL INFORMATION
The purpose of the manual is to properly specify size, install, interconnect and operate the dV
Sentry motor protection filter.
For most current information, please refer to website
http://www.mtecorp.com/products/dv-sentry-dvdt-filters/
This manual is intended for use by personnel experienced in the operation and maintenance of
inverters. Because of the high voltages required by the filter, inverter and the potential dangers
presented by rotating machinery, it is essential that all personnel involved in the operation and
maintenance of this filter 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 the filter and inverter to which it is connected.
Receipt & Repair Statement
Upon Receipt of this Filter:
The dV Sentry 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 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 IP23 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
CE Marked Warranty
Three years from the date of shipment. See http://www.mtecorp.com/industry-leading-warranty/
for details.
