3. HOW TO SELECT

Selection Guide

The dV Sentry Motor Protection Filter is intended for use on inverter duty motors. It will

typically be used with lead lengths up to 1,000 feet. The dV Sentry Motor Protection Filter will
provide both common mode and differential mode reduction to prevent overvoltage that can
occur due to reflected wave phenomena. The differential mode filtering reduces EMI,
increases motor life, and reduce cables voltage stress. The added common mode protection
will reduce bearing failures, degradation of cable insulation to ground, and further reduce EMI.

The suitability of this filter for a specific application must therefore be 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 this filter. Nor will MTE
Corporation assume patent liability with respect to the use of information, circuits or equipment
described in this instruction manual.

*For non-inverter duty motors, please refer to the SineWave Guardian filter.

dV Sentry Motor Protection Filters are available in Panel, NEMA 1/2, and 3R mechanical
configurations.

Please verify information below for proper selection:

 Lead Length: This product is suitable for applications with motor leads up to 1,000 ft.

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.

6. HOW TO INSTALL

Installation Checklist

dV/dt filters are supplied in the following mechanical configurations:

 Panel mounted assemblies
 Floor mounted general purpose NEMA 1/2 & 3R cabinets

Panel 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 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). Open panel dV Sentry 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 heat flow. Avoid locations
where the filter would be subjected to excessive vibrations. Locate the filter as close to the
inverter as possible.

Figure 6-2 contain panel outline drawings for the various current ratings and show proper panel
alignment. For filters above 130 amps refer to Figure 6-3 for the dimensions of the separately
mounted filter. Connect the motor and inverter leads to the reactor terminals to complete the
filter wiring.

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 and front clearance of thirty-six (32 inches for proper
heat dissipation and access.
