Important Notes About Installation
• The system must be installed only by qualified service personnel.
• Always consult local codes for mounting pad requirements.
• Consult local utility codes for additional cabinet grounding and utility requirements.
• Consult the local gas company for correct meter type and riser location.
• Whenever possible, it is best that the enclosure be installed above flood zones .
• Precast Mounting Pads may either be purchased from Alpha or poured in place. The pad must be
capable of holding 1,000 lbs (minimum). Rebar may be placed in a crosshatch pattern for pad
reinforcement, as needed.
• If the pad is to be located in an area with a deep frost line or unstable soil, concrete pylon footings (4"
diameter X 4' deep, or 1' deeper than the regional frost line) can be placed below the concrete pad, in
front of and below the (4) mounting features.
• The top of the pad must be above grade to reduce the buildup of debris around the base of the cabinet.
• Adequate space must be allowed for Cable TV input/output conduit; plant grounding electrode
conductor(s); RF cable entrance via (1) 4", (2) 3" or (3) 2 1/2" rigid conduit sweep(s) with 2' bend radius
(minimum); and fiber optic cable entrance (refer to fiber manufacturer's specification for minimum
bend radius requirements).
• Prior to pouring concrete, any wire running through the pad must have a thermal expansion jacket (i.e.,
PVC) to prevent cracking of the concrete during lightning strikes.
• Alpha Technologies is not responsible for broken welds or other damage to the cabinet caused by
improper installation.
• A 25+ year vapor barrier must be used between the concrete pad and the base of the enclosure to further
inhibit the ingress of moisture. Alpha Technologies is not responsible for water damage or moisture
damage resulting from improper installation.
• Concrete filled, 6" diameter steel posts (or equivalent) can be placed at the corners of the pad to reduce
exposure to accidental traffic damage.
• All dimensions are given in inches.

representative.
