F or grounding of equipment and miscellaneous metallicobjects, #6 A WG minimum is required.Exceptions Connection from an isolated ground bar (IGB) to master ground bar (MGB) isaccomplished using #2 to #6 A WG . The external ground bar (EGB) is grounded through a 2 -inchwide, 16 -gauge copper strap, if available; otherwise, 2 -#6 A WG wires can be used. If the #6A WG wires are used, then they must be connected at opposite ends of the EGB and have aminimum separation of 12 -inches between them.Below Ground All wire must be #2 A WG as a minimum. Ground rods are to be a minimum of8 feet long and 5/8 -inch in diameter . In the case of a deep basement next to the rod, the rodmust be long enough to extend 3 feet below the basement floor .Power ConsiderationsThe Base Control Unit (B CU) is designed for 100/240 V AC (88–300 Vrms) @ 45–66 Hz, +21to +30 VDC or —60 to —40VDC .The system configuration determines which power cables are installed. The ground cable isalways installed first. Based on the system configuration perform the appropriate proceduresdescribed in Chapter 4 Access P oint Hardware Installation .DC Power (RF Head)The DC power cable is orderable in a variety of lengths as indicated in T able 3 -3 below .Depending on site configuration all of one length or a combination of lengths (up to 4) may beused.68P09277A59 -5 3 -5Draft OCT 2006

Access P oint Hardw are Installation R emote GPS Cable•The mounting pipe for the RGPS head should be mounted vertically with less than fivedegrees of tilt.•It is recommended that the RGPS head be installed using the supplied mounting mast andmounting hardware. Care should be taken to ensure that the RGPS chassis does not comeinto contact with any metal surfaces. F ailure to properly isolate the RGPS chassis fromother conductive surfaces can lead to RGPS head failure. The supplied mounting hardwarehas been designed to provide the required RGPS chassis isolation.•P osition the RGPS head to have an unobstructed view of the sky and to minimize the chanceof debris (leaves, dirt, snow , ice, etc.) accumulating on the radome of the RGPS head.•The RGPS head must have a clear view of the sky , preferably to within 10 degrees of thehorizon in all directions. The total blockage of the sky (due to buildings, mountains, etc.)should be less than 50%.•Place the RGPS head as far away from the transmit antenna as possible to avoid RFinterference issues.•Place the RGPS head at least 15 m away from lightning rods, towers, or structures thatattract lightning. RGPS head damage is usually not the result of a direct lightning strike,but of a lightning strike on a nearby structure. Also, since a lightning rod is connectedto an earth ground, it can act as a shield and create a shadow that may block or reducethe signal from a satellite.•A fter the Base Control Unit (B CU) is powered up (approximately 15 minutes), check theRGPS signal strengths with thegstatuscommand on the B CU MMI port.An optimal installation will have at least one satellite (SV) with an RS SI value 50,and at least four (4) satellites with RS SI values 45.A minimal installation should have at least four (4) satellites with RS SI values 40.•The RGPS head is rated for ambient air temperatures from –40°C (–40°F) to 75°C (167°F),and has ratings for humidity , shock, waterproof , UV light resistance, vibrations, salt fog,ESD , EMI, and altitude.•The RGPS system used for the Access P oint will support up to 1 km (3280 ft.) of overallcable length from the RGPS head. If a long cable run needs to be broken into pieces,minimize the number of breaks in the cable.68P09277A59 -5 3 -9Draft OCT 2006

Access P oint Hardw are Installation RF GPS CableTable 3 -8 Local GPS Antenna Mounting Consider ationsHeading21The mounting pipe for the Local GPS Head should be mounted vertically with lessthan five (5) degrees of tilt.2The Local GPS Head requires a clear view of the sky , preferably to within ten (10)degrees of the horizon in all directions. The more sky that is observed increasesthe number of potential satellites that can be tracked, resulting in better LocalGPS performance.3During normal operation, the Local GPS Head continuously tracks a minimum offour (4) GPS satellites. However , it is theoretically possible to operate the BTS bytracking only one (1) GPS satellite. Motorola does not recommend tracking only one(1) GPS satellite unless there has been an accurate site survey .4Place the Local GPS Head where RF obstructions of the sky are minimal. Theskyincludes everything to within ten (10) degrees of the horizon in all directions. RFobstructions include buildings, towers, natural rock formations, snow , foliage, anddebris.The mounting of the Local GPS head on antenna towers is notrecommended due to increased risk of damage due to lightning strikes. Iftower mounting is necessary the Local GPS head should mounted at thelowest point possible and still maintain an unobstructed view of the sky .5Separate the Local GPS Head from other radiating sources. Excessive RF energycan degrade the Local GPS Head’s ability to observe the GPS satellites. The LocalGPS Head receives on the GPS L1 frequency of 1575.42 MHz and incorporatesfilters to minimize the effects of potential RF interference, however , strong radiantscan overwhelm the filters, thus degrading the units reception capability .6The Local GPS Head is rated for ambient air temperatures in the range -40 to +50degrees C , and has ratings for humidity , shock, waterproofing, UV light resistance,vibrations, salt, fog, ESD , EMI, and altitude.7An RF gain of between +10 dB and +26 dB should be provided to the Local GPSreceiver antenna input. The GPS antenna supplied in the CGDSGPSKITF4NM50kit provides a nominal gain of +25 dB. The total signal loss from theCGDSGPSKITF4NM50 antenna output and Local GPS antenna input must be lessthan 15 dB at 1.575 GHz.68P09277A59 -5 3 -11Draft OCT 2006

The colors are matched tothe RF Head DC power cables. The colors are as follows:•RFU 1 = RED•RFU 2 = BL UE•RFU 3 = YELLOW•RFU 4 = GREENRemove the appropriate color sticker and apply it to theunderside of the RF Head. Use the appropriate tie-wraps toidentify the DC power cables and the Fiber Optic cables.F or Example:The first RF Head used would have the power connector identified with theRED sticker , and the power and fiber cables would be tagged withthe RED tie-wraps.3Prepare the RF Head for hoisting.A ttach carabiner to handle of RF Head.Use the block and tackle to carefully hoist (so cables will not be damaged)the RF Head Assembly up to the tower .

Ground Cabling Installation Chapter 4: Access P oint Hardw are InstallationGround Cabling Installation■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■ObjectiveThis section contains the procedures for installing the ground cable to the Antenna, B CU ,RGPS , and RF Head.General Grounding GuidelinesThe site should have had an external ground ring or bus bar being used. The ground ring andbus bar should be an integral part of the structures that will hold the equipment. ReferenceGrounding Guidelines for Cellular R adio Installations (Motorola part number 68P81150E62)orAppendix C of Standards and Guidelines for Communication Sites.BCU GroundingThe B CU should be tied to a single point grounded to the system master ground. Allinterconnect cables should be in metallic sealtight type conduit or solid shield RF cables. It isrecommended that these cables be run in raceways to reduce the loop dimensions of the cableruns. This minimizes the effect of inducted currents caused by the intense electromagneticfield of lightning current.RF Head GroundingAll RF cables should be in metallic sealtight type conduit or solid shield RF cables. It isrecommended that these cables be run in raceways to reduce the loop dimensions of the cableruns. This minimizes the effect of inducted currents caused by the intense electromagnetic fieldof lightning current. A ground lug with captive screws is provided on the RF Head to attachthe ground wire.DC Power GroundingThe DC power cables from the B CU to the RF Head are routed through conduit. The conduitis grounded to the master ground.Antenna GroundingThe antenna is grounded through the RF Head.4 -20 68P09277A59 -5Draft OCT 2006
