3.0 Site Preparation
The site must be planned so that the enclosure will receive good air fl ow. In areas of extreme heat,
position the enclosure so that it will be shaded from the afternoon sun. In areas of prevailing winds,
it is best that the enclosure be located so that the sides of the cabinet face the winds instead of the
doors. This will greatly reduce the buildup of sand or snow against the enclosure’s air vents.
In areas of potential fl ooding, the geographical site and concrete pad must be located above the fl ood
plain. Pedestals are available to raise the Power Node enclosures above expected snow and water
levels.
The enclosure must be placed where it will be free of obstructions, allowing easy access to the doors
for service or equipment access. For ventilation and maintenance, allow a minimum space of 36
inches in the front and 36 inches in the rear, between the enclosure and other solid structures.
Place the enclosure well away from ground level sources of forced water, such as underground
sprinkler systems and direct roadway splash.
The concrete pad drawing (Section 3.1) contains all of the required mounting details, including
electrical service and cable plant entrances.
The vapor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar paper) must
initially extend at least 6" in all directions around the perimeter of the enclosure and be trimmed closer
to the enclosure, using the appropriate utility knife or cutting tool.
