2. Pre-Installation
The site must be planned so that the enclosure will receive good air flow. If possible, in areas of extreme heat, it is best to
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 flooding, the geographical site and concrete pad must be located above the flood 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 is provided in the Pre-Installation Section of this manual 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.
WARNING: Never transport the unit with batteries installed. Batteries must ONLY be installed after the
unit is transported to the site and secured to the pad. Transporting the unit with batteries
installed may cause a short circuit, fire, explosion, and/or damage to the battery pack,
enclosure and installed equipment. Damage caused by improper shipping or transporting a
unit with batteries installed is not covered under warranty.
