Do not select a location that is, or may be,subject to submersion (i.e. diversion channels, sub–basements, etc).While the RF and Power Cabinet are well insulated from theenvironment, they will not tolerate submersion.–There should be adequate clearance through doors and passagewaysto allow movement of the cabinet from the delivery area to theinstallation site.–Verify, prior to final site selection, the availability and accessibilityto good grounding (ground system resistance must be less than 10Ohms, with 5 Ohms or less being the goal; see ”RecommendedDocumentation” for Grounding Guidelines), RF cabling, Telcowiring, and 208–240 VAC power.–There should be adequate space available for the future addition ofexpansion or optional equipment.–The location of an AC power pedestal to mount the AC meter, mainbreaker, generator plug, etc. (if necessary), is at the installers option.–Every effort should be made to minimize the separation distancebetween the RF and Power Cabinet (see Table 2-1) for maximumcable length between cabinetsTable 2-1: DC Cabling Size – Maximum Cable LengthCable Size Resistance per 1,000 ft @ 50Deg CmW (THHN Cable) Maximum Cable Length(Max Total Voltage Drop  0.4V, assumes 90A per cable)2/0 AWG 96.8 (Superflex) 6.7 m (22 ft)4/0 AWG 54 (Duraflex) 12.5 m (41 ft)NOTE–3.65 m (12 ft.) is the length of the # 2/0 AWG DC Power Cable supplied with the Power Cabinet.–If a custom cable is used, 610 mm (2 ft.) should be reserved at both ends to allow for the distance from theedge of the cabinet to the power terminals.2
Site Preparation – continuedDRAFTSCTM 4812ET RF and Power Cabinet Hardware Installation Manual Apr 2001V02.0336Rooftop Location In addition to the Indoor location considerations, the followingadditional items should be considered when choosing a Rooftoplocation:Roof load carrying limits must be reviewed and anappropriate support structure must be installed to supportthe cabinets as required.WARNINGThe cabinets must be elevated sufficiently above the roofsurface to prevent water from puddling around its base.Although the cabinets are well insulated from theenvironment they will not tolerate submersion.CAUTIONLoading Considerations (also see Table 2-2):–A single SC 4812ET RF Cabinet can weigh up to 680 kg. (1500lbs) and a single Power Cabinet enclosure can weigh up to 1590 kg.(3500 lbs) with the batteries installed (batteries are shippedseparately). Expansion enclosures and optional equipment will addweight (refer to the introduction section of this manual for obtainingdetailed information on the optional equipment).The Power Cabinet as shipped without batteries installedcan weigh up to 544 kg (1200 lbs.).NOTE–When the cabinet is to be roof mounted, be sure to consider the rainand/or snow loading of the region when determining whether theroof can support the load.Zoning requirements – that relate to building mounted equipmentshould be checked for any restrictions that may affect cabinet or antennaplacement.Adequate clearance through doors, passageways and stairwells to allowmovement of the cabinet from the delivery area to the installation site.Minimum separation distance – Every effort should be made tominimize the separation distance between the RF and Power Cabinet(see Table 2-1).Cabinet Weight Table Table 2-2 lists the approximate weight of both the RF and Powercabinets in various site configurations. . . . continued on next page2

Rooftop Roof load carrying limits must be reviewed and anappropriate support structure must be installed to supportthe RF and Power Cabinet as required.WARNINGThe cabinet must be elevated sufficiently above the roofsurface to prevent water from puddling around its base.Although the cabinets are well insulated from theenvironment they will not tolerate submersion.CAUTION . . . continued on next page2
Site Preparation – continuedDRAFTSCTM 4812ET RF and Power Cabinet Hardware Installation Manual Apr 200150Refer to Figure 2-5 and Figure 2-6 for proper position of mountinglocations when designing the support structure.For most rooftop installations all of the connections to the cabinet willbe made through the rear of the cabinet I/O area. For this reason, thecabinet must be set in place and bolted down prior to running anyconduits or wiring. Conduit/wire routing will be discussed in Chapter 5.Lightning protection is included in the cabinet. A good earth ground(ground system resistance must be less than 10 Ohms, with 5 Ohms orless being the goal) is required for the lightning protection equipment toperform properly. Refer to Motorola’s guidelines (Motorola Publication68P81150E62) for details on the design of a grounding system. Conformto local electrical construction standards for conduit materials and sizing.Rooftop (Elevated)For a rooftop installation which is elevated sufficiently above the roofsurface, most of the connections can be made through the bottom of thecabinet by terminating the conduit at the bottom of the rear I/O area. SeeFigure 2-6 for recommended conduit/cable entrance layout.New Concrete PadThe mounting surface must be flat. Door closure problemsmay occur if the cabinets are not installed on a flat surface.To help reduce the chance of damage caused by lightningstrikes, it is required that a ground ring be constructedwhen the pad is built. See section titled ”Ground SystemInstallation”.CAUTIONVariations in pad construction methods may be required to comply withlocal conditions, practices, or building codes.Install the grounding system, and electrical conduits (see Figure 2-3,Figure 2-4, and Figure 2-6) prior to pad construction. Refer to theMotorola guidelines (Motorola Publication 68P81150E62) for details onthe design of a grounding system. Conform to local electricalconstruction standards for conduit materials and sizing. Refer toTable 2-6 and Table 2-7 for minimum bend radius of antenna cables andmaximum number of cables in a conduit.If it is desired to make cabling through the bottom of the cabinets, it isrecommended that the conduits be positioned using the dimensionsgiven in Figure 2-5 prior to pouring the concrete pad. Installation in thismanner allows for the connections to the RF and Power Cabinet to bemade through the bottom of the I/O area, although it may be desirable tomake the antenna connections through the rear wall. For the connectionsthat are made through the bottom of the I/O area, conduits and wiringcan be installed prior to arrival of the cabinet. . . . continued on next page2

The less sky thatcan be observed the fewer the number of potential satellites that canbe tracked and hence the poorer the RGPS performance.–For general operation, the RGPS Head needs to be able tocontinuously track signals from at least four (4) GPS satellites. It istheoretically possible to operate the BTS with only one GPSsatellite visible, however, operating in this mode it is notrecommended and requires an accurate site survey.2
Site Preparation – continuedDRAFTSCTM 4812ET RF and Power Cabinet Hardware Installation Manual Apr 200158–Place the RGPS Head where RF obstructions of the sky areminimized. The “sky” includes everything to within ten degrees(10°) of the horizon in all directions. RF obstructions includesbuildings, towers, snow, foliage and debris.–Separate the RGPS Head from radiating sources. Excessive RFenergy can degrade the RGPS head’s ability to observe the GPSsatellites. The RGPS head receives on the GPS L1 frequency of1575.42 MHz and has filters incorporated within to minimize theeffects of potential RF interference, however, strong radiators canoverwhelm the filters, thus degrading the units reception capability.–The RGPS Head is rated for ambient air temperatures from –40 DegC to +50 Deg C, and has ratings for Humidty, Shock, Waterproof,UV Light Resistance, Vibrations, Salt, Fog, ESD, EMI, andAltitude.–The RGPS system will support up to 2000 feet (610 m) of overallcable length from the RGPS Head to the last connected base station.If a long cable run needs to be broken into pieces, minimize thenumber of breaks in the cable.2

Installing RGPS – continuedApr 2001V0A.03 SCTM 4812ET RF and Power Cabinet Hardware Installation ManualDRAFT125RGPS MountingConsiderationsThe RGPS Head requires specific mounting considerations in order toproperly observe the GPS satellites.–The mounting pipe for the RGPS Head should be mountedvertically with less than five degrees (5°) of tilt.–The RGPS Head needs to have a clear view of the sky, preferably towithin ten degrees (10°) of the horizon in all directions. The lesssky that can be observed the fewer the number of potential satellitesthat can be tracked and hence the poorer the RGPS performance.–For general operation, the RGPS Head needs to be able tocontinuously track signals from at least four (4) GPS satellites. It istheoretically possible to operate the BTS with only one GPSsatellite visible, however, operating in this mode it is notrecommended and requires an accurate site survey.–Place the RGPS Head where RF obstructions of the sky areminimized. The “sky” includes everything to within ten degrees(10°) of the horizon in all directions. RF obstructions includesbuildings, towers, snow, foliage and debris.–Separate the RGPS head from radiating sources. Excessive RFenergy can degrade the RGPS head’s ability to observe the GPSsatellites. The RGPS head receives on the GPS L1 frequency of1575.42 MHz and has filters incorporated within to minimize theeffects of potential RF interference, however, strong radiaters canoverwhelm the filters, thus degrading the units reception capability.–The RGPS Head is rated for ambient air temperatures from –40° Cto +50°C, and has ratings for Humidity, Shock, Waterproof, UVLight Resistance, Vibrations, Salt, Fog, ESD, EMI, and Altitude.–The RGPS system will support up to 2000 feet (2609 m) of overallcable length from the RGPS Head to the last connected base station.If a long cable run needs to be broken into pieces, minimize thenumber of breaks in the cable.A

Use the Double–Dpunch CGDS50748149 to punch the Double–D hole (see Figure E-2). Repeat as required.3To punch the round hole for the ground cable, AC power cable, etc., use a standard electrician holepunch set. As with all tools, follow the safety instructions from the manufacturer of the tool. Thehole required for the ground wire bushing supplied is 23 mm (7/8”).4If necessary use a de–burring tool or sandpaper to remove any sharp burrs around the holes thatwere punched. E

Scope and IntroductionThe purpose of this appendix is to provide instruction on how to connecttwo SC 4812ET cabinets to a single SC 4812ET Power Cabinet. Pleasenote that one fully loaded Power Cabinet (6 rectifiers) is rated only at300A DC. As a result, only a total 9 Sector–carriers of capacity can besupported in the two “co–located” RF Cabinets (e.g. one 3–sector,1–carrier cabinet and one 3–sector, 2–carrier cabinet), or inadvertentlytripping the circuit breaker could result.The SC 4812ET Power cabinet provides 27 Volts DC power to anassociated SC 4812ET RF Cabinet. For sites where the SC 4812ET willbe co–located with an SC 4812ET, it can be advantageous for space andother considerations to be able to use the SC 4812ET Power Cabinet as aDC source for the second RF Cabinet.This section describes how to install and configure the equipment toprovide this functionality. . . . continued on next pageF

Installing RF GPS – continuedDRAFTSCTM 4812ET RF and Power Cabinet Hardware Installation Manual Apr 2001V0H.01184RF GPS MountingConsiderationsThe RF GPS Head requires specific mounting considerations in order toproperly observe the GPS satellites.Table H-2: Mounting ConsiderationsnConsideration1The mounting pipe for the RF GSP Head should be mounted vertically with less than five (5)degrees of tilt.2The RF GPS Head requires a clear view of the sky, preferably to within ten (10) degrees of thehorizon in all directions. The less sky that can be observed the fewer the number of potentialsatellites that can be tracked resulting in poorer RF GPS performance.3For general operation, the RF GPS Head needs to be able to continuously track signals from atleast four (4) GPS satellites. It is theoretically possible to operate the BTS with only one (1) GPSsatellite visible, however, operating in this mode is not recommended and requires an accurate sitesurvey.4Place the RF GPS Head where RF obstructions of the sky are minized. The “sky” includeseverything to within ten (10) degrees of the horizon in all directions. RF obstructions includebuildings, towers, snow, foliage and debris.5Separate the RF GPS Head from other radiating sources. Excessive RF energy can degrade the RFGPS Head’s ability to observe the GPS satellites. The RF GPS Head receives on the GPS L1frequency of 1575.42 MHz and has filters incorporated within to minimize the effects of potentialRF interference, however, strong radiants can overwhelm the filters, thus degrading the unitsreception capability.6The RF GPS Head is rated for ambient air temperatures from –40 degrees C to + 50 degrees C,and has ratings for humidity, shock, waterproof, UV light resistance, vibrations, salt, fog, ESD,EMI, and altitude.7If the overall length from the RF GPS Head to the BTS is greater than 50 feet, the cable style andlength should be determined by the site configurations. The maximum loss should be less than4.5 dBm @ 1575 MHz for all cabling and connections between the GPS Head and the RF cabinet.A 1/2” cable “pigtail” should always be used to exit thecabinet before transitioning to a larger cable. This willensure a proper seal on the rubber I/O boot. It is suggestedthat the supplier cable be cut to the desired length toachieve this.NOTEH
