2.0 Site Preparation
2.1 Site Considerations
• Where possible, select a site that is above the 100 year fl ood plain, and away from
houses.
• Place in a shaded location to minimize the effects of solar loading.
• Avoid locating the enclosure where it is an obstruction and would inhibit visibility.
• Locate the enclosure away from sprinkler systems or other sources of forced water.
• Locate the enclosure out of the prevailing wind to minimize the buildup of snow or the
accumulation of wind-borne dust.
• Determine if soil conditions are suitable for the installation of the applicable required
grounding system.
• Verify utility power cabling has been run and terminated at the site.
2.2 Acoustics
Nuisance noise is of concern to nearby residents. Nuisance noise is a directional noise
which can cause discomfort during engine-generator operation to nearby residential
occupants (audible levels may vary due to absorption and refl ection caused by the immediate
surroundings).
Audible impact on neighborhoods is mitigated by recent advances in muffl ers, fl ame resistant
sound materials, intake air sound attenuators, along with improved cabinet airfl ow dynamics.
The fi gures below show the measured audible levels from PN-6x-T 7.5kW generator at full
load. Note the symmetry of these emissions. Deployment decisions must include noise
consideration. The elimination of nuisance noise, and the reduction of directional impact
within a residential community, is critical.
