procurement specifications, it may be helpful to the
Contractor to show the proposed mounting
requirements on a sketch.
**************************************************************************
3.1
INSTALLATION
**************************************************************************
NOTE: Designer shall ensure that project architect
and structural engineer are aware of significant
wall and floor loading caused by three-phase,
enclosed power filters. Filter assemblies can weigh
from 227 kg to over 454 kg 500 pounds to over 1000
pounds depending on ampere rating. Show sufficient
mounting details on plans to support the filters.
Also coordinate filter installation with project
mechanical engineer to ensure the provision of
adequate ventilation from heat dissipation.
**************************************************************************
NFPA 70. Install filter assemblies on the [outer] [inner] surface of the
shielded enclosure and support them independently from the shielding.
Coordinate mounting of power filter units with other filters and shielded
enclosure penetrations.
3.2
GROUNDING
Ground filters in accordance with Section [13093N RADIO FREQUENCY SHIELDED
ENCLOSURES DEMOUNTABLE TYPE] [13094N RADIO FREQUENCY SHIELDED ENCLOSURES
WELDED TYPE]. [Provide brass ground stud on line side in filter terminal
compartment.]
3.3
PAINTING OF FILTER UNITS
**************************************************************************
NOTE: If painting is not required, delete this
paragraph. If painting of filters is only painting
in project, insert in this paragraph the applicable
paragraphs of Section 09900, "Paints and Coatings."
**************************************************************************
Paint exterior surface of [individually mounted filters] [filter unit
assemblies] as specified in [Section 09900 PAINTS AND COATINGS] [Section
16050N BASIC ELECTRICAL MATERIALS AND METHODS]. Paint color shall be
[manufacturer's standard] [as directed by Contracting Officer] [as
indicated]. Clean grounding surfaces so that they are free of paint and
insulating material.
