Grounding
NOTE: For cable shield grounding follow the drive manufacturer’s recommendations.
Location & Spacing
Panel mounted (open-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). Panel mounted dV Sentry
Filters generate heat and should be positioned away from heat sensitive components. Ensure
that proper panel orientation is maintained. Avoid locations where the filter would be subjected
to excessive vibrations. Locate the filter as close to the drive as possible. For applications where
the cable length exceeds fifty (50) feet between the drive and filter, contact MTE.
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. Locate the filter as close to the drive as possible.
WARNING
The filter must always be grounded with a grounding conductor connected
to ground terminals.
For panel mounted
units, ensure a 2” x 2” area is cleaned of paint and
varnish on lower mounting bracket for ground connection.
