031-103-B0-004, Rev. D 6
Installation Notes
• The system must be installed only by qualifi ed 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 fl ood 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 fi ber optic cable
entrance (refer to fi ber manufacturer’s specifi cation 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 fi lled, 6" diameter steel posts (or equivalent) can be placed at the corners of the pad to reduce exposure to
accidental traffi c damage.
• All dimensions are given in inches.
• For further information regarding this installation, contact Alpha Technologies or your nearest Alpha representative.
