Site Preparation – continued – Adequate ventilation must be available to dissipate heat loads of 7,500 Watts (25,600 Btu / hr) for the RF Cabinet and 3,000 Watts (10,300 Btu / hr) for the Power Cabinet (a total of 10,500 Watts; 35,900 Btu / hr), and maintain a maximum temperature of no greater than 50 Deg C (122 Deg F). – The AC meter and main disconnect should not be mounted to either cabinet. – Locations should be selected that will minimize accidental or intentional vandalism.
Site Preparation – continued Rooftop Location In addition to the Indoor location considerations, the following additional items should be considered when choosing a Rooftop location: 2 WARNING Roof load carrying limits must be reviewed and an appropriate support structure must be installed to support the cabinets as required. CAUTION The cabinets must be elevated sufficiently above the roof surface to prevent water from puddling around its base.

Site Preparation – continued In addition to the Indoor location considerations, the following additional items should be considered when choosing an outdoor location: – The cabinet should be placed in a location with appropriate clearance from any obstructions. For minimum clearances see Chapter 1. – It should be the practice of any installing company to acquire, in advance of construction, the rights of way from landowners, and permits or approvals from public authorities.
Site Preparation – continued NOTE It may not be necessary or desirable to run the transmission lines in any conduit at all. In this case the transmission lines should be protected from falling objects (i.e., ice, etc.) or from being stepped on. 2 Table 2-6: Heliax Cable Loss and Minimum Bend Radii dB loss per meter dB loss per foot Min. bend radius Heliax Cable Motorola Part No. @ 1 GHz @ 2 GHz @ 1 GHz @ 2 GHz Metric U.S.
Site Preparation – continued IMPORTANT * The Power Cabinet is rated at 130 Amps (100 Amps continuous / 130 Amps non–continuous, in the range of 208–240V AC, see Table 5-32 for details). Maximum cable size that can be accommodated is 300 kc mil. Cabling sizing should be determined by Local Electrical Codes, using 90Deg C rated conductors, and derated for 50 Deg C operation.
Site Preparation – continued Power Cabinet Alarm Cable – A Twelve (12) wire, Six (6) twisted pair cable [Cable supplied with the Power Cabinet is 4.5 m (15 ft) in length]. 2 NOTE Custom cable lengths are available from Storm Products (214–637–1381); 9215 Premier Row, Dallas, TX. 75247. Part number “070197–6SA” for Non–Plenum rated cable.
Site Preparation – continued Drilling Introduction The following includes steps that must be followed to safely drill the mounting holes. Check the mounting hardware to be used to make sure you use the correct drill bit sizes. 2 CAUTION Motorola recommended anchor bolts (Motorola P/N CGDS97400036) must be used to assure safety in the event of an earthquake.
Site Preparation – continued Table 2-8: Drilling Procedure Step Action 2 Position the end of the drill bit in the center of the first mark on the floor. Stabilize the drill by holding the drill handle at the 90_ position, refer to Figure 2-1. Rest the drill against your leg while drilling to counter the drill’s tendency of rotating out of your hand while drilling through reinforcement bars and stone aggregate.
Site Preparation – continued Table 2-8: Drilling Procedure Step Action 4 Have a second installer turn on the shop vacuum and place the nozzle near the hole to collect dust and debris (see Figure 2-2). This will extend the life of the drill bit, and give you a better idea of how deep the hole is. Wrapping a piece of electrical tape around the drill bit to indicate the desired depth is suggested.
Site Preparation – continued Refer to Figure 2-5 and Figure 2-6 for proper position of mounting locations when designing the support structure. For most rooftop installations all of the connections to the cabinet will be made through the rear of the cabinet I/O area. For this reason, the cabinet must be set in place and bolted down prior to running any conduits or wiring. Conduit/wire routing will be discussed in Chapter 5. 2 Lightning protection is included in the cabinet.
Site Preparation – continued CAUTION Conduits that are pre–installed in a concrete pad below grade must be capped at the time of conduit installation to prevent rainwater from collecting in the conduit. 2 WARNING If a precast concrete foundation pad is used, the pad should be in place before the cables are installed. This will avoid an unsafe condition caused by personnel reaching under a pad, as it is lowered, to feed cable through the pad openings.
Site Preparation – continued Installation Procedure: Install the concrete pad and ground system as described in Table 2-9. 2 Table 2-9: Concrete Pad and Ground System Installation Procedure Step Action 1 Ensure that the pad location is firm and level. If the ground around the location is not firm, compact the soil and construct a level base for the pad using a minimum of six inches of gravel or per local code requirements.
Site Preparation – continued Grounding Ring: The following information details installation of the site grounding ring. Refer to Figure 2-3 for detail dimensions.

Site Preparation – continued – Place the RGPS Head where RF obstructions of the sky are minimized. The “sky” includes everything to within ten degrees (10°) of the horizon in all directions. RF obstructions includes buildings, towers, snow, foliage and debris. – Separate the RGPS Head from radiating sources. Excessive RF energy can degrade the RGPS head’s ability to observe the GPS satellites. The RGPS head receives on the GPS L1 frequency of 1575.
