Grounding Considerations Above Ground For ground rings and the interconnection of internal and external ground rings, #2 to #6 AWG may be used. For grounding of equipment and miscellaneous metallic objects, #6 AWG minimum is required. Exceptions Connection from an isolated ground bar (IGB) to master ground bar (MGB) is accomplished using #2 to #6 AWG. The external ground bar (EGB) is grounded through a 2-inch wide, 16-gauge copper strap, if available; otherwise, 2-#6 AWG wires can be used. If the #6 AWG wires are used, then they must be connected at opposite ends of the EGB and have a minimum separation of 12-inches between them. Below Ground All wire must be #2 AWG as a minimum. Ground rods are to be a minimum of 8 feet long and 5/8-inch in diameter. In the case of a deep basement next to the rod, the rod must be long enough to extend 3 feet below the basement floor. Power Considerations The Base Control Unit (BCU) is designed for 100/240 VAC (88–300 Vrms) @ 45–66 Hz, +21 to +30 VDC or —60 to —40VDC. The system configuration determines which power cables are installed. The ground cable is always installed first. Based on the system configuration perform the appropriate procedures described in Chapter 4 Access Point Hardware Installation . DC Power (RF Head) The DC power cable is orderable in a variety of lengths as indicated in Table 3-3 below. Depending on site configuration all of one length or a combination of lengths (up to 4) may be used. 68P09277A59-5 3-5 Draft OCT 2006 Earth Ground and Power Cables Chapter 3: Cable Descriptions Table 3-3 RF Head DC Power Cable Description and Part Numbers Part Number Description Cable Qty 1–4 3089298C01 Power Cable, 20 m (65.6 ft) 1–4 3089298C02 Power Cable, 40 m (131.2 ft) 1–4 3089298C03 Power Cable, 60 m (196.8 ft) 1–4 3089298C04 Power Cable, 80 m (262.4 ft) 1–4 3089298C05 Power Cable, 100 m (328.0 ft) 3-6 68P09277A59-5 Draft OCT 2006 Access Point Hardware Installation Antenna Cable Antenna Cable ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Objective This section contains general information on the antenna cabling.

Mounting Considerations The RGPS Head requires specific mounting considerations in order to properly observe the GPS satellites. 3-8 68P09277A59-5 Draft OCT 2006 Access Point Hardware Installation Remote GPS Cable • The mounting pipe for the RGPS head should be mounted vertically with less than five degrees of tilt. • It is recommended that the RGPS head be installed using the supplied mounting mast and mounting hardware. Care should be taken to ensure that the RGPS chassis does not come into contact with any metal surfaces. Failure to properly isolate the RGPS chassis from other conductive surfaces can lead to RGPS head failure. The supplied mounting hardware has been designed to provide the required RGPS chassis isolation. • Position the RGPS head to have an unobstructed view of the sky and to minimize the chance of 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 the horizon 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 RF interference issues. • Place the RGPS head at least 15 m away from lightning rods, towers, or structures that attract 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 connected to an earth ground, it can act as a shield and create a shadow that may block or reduce the signal from a satellite. • After the Base Control Unit (BCU) is powered up (approximately 15 minutes), check the RGPS signal strengths with the gstatus command on the BCU MMI port. An optimal installation will have at least one satellite (SV) with an RSSI value and at least four (4) satellites with RSSI values 45. 50, A minimal installation should have at least four (4) satellites with RSSI 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 Point will support up to 1 km (3280 ft.) of overall cable 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 3-9 Draft OCT 2006 RF GPS Cable Chapter 3: Cable Descriptions RF GPS Cable ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Objective This section contains general information on the Radio Frequency Global Positioning System receiver (RF GPS) antenna cabling. More commonly referred to as Local GPS. Refer to for installation information. Cable Label Refer to Table 3-1 for the labels used to identify the cables that will be shown in illustrations throughout this chapter. Table 3-7 Local GPS Cable Description and Part Numbers Part Number Description Cable Qty Receiver SGRG4030 Assembly, GPS, RF Module CGDSGPSKITF4NM50 Assembly, Receiver, RF GPS with 50 ft. cable An SMA to N adapter is required; otherwise, a smaller diameter cable must be made with an SMA connector on one end, with a maximum loss of <4.5 dB. Surge Protection RF GPS antenna requires lightning protection. Mounting Considerations Refer to Table 3-8 for Local GPS mounting considerations. 3-10 68P09277A59-5 Draft OCT 2006 Access Point Hardware Installation Table 3-8 RF GPS Cable Local GPS Antenna Mounting Considerations Heading2 The mounting pipe for the Local GPS Head should be mounted vertically with less than five (5) degrees of tilt. The 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 increases the number of potential satellites that can be tracked, resulting in better Local GPS performance. During normal operation, the Local GPS Head continuously tracks a minimum of four (4) GPS satellites. However, it is theoretically possible to operate the BTS by tracking only one (1) GPS satellite. Motorola does not recommend tracking only one (1) GPS satellite unless there has been an accurate site survey. Place the Local GPS Head where RF obstructions of the sky are minimal. The sky includes everything to within ten (10) degrees of the horizon in all directions. RF obstructions include buildings, towers, natural rock formations, snow, foliage, and debris. The mounting of the Local GPS head on antenna towers is not recommended due to increased risk of damage due to lightning strikes. If tower mounting is necessary the Local GPS head should mounted at the lowest point possible and still maintain an unobstructed view of the sky. Separate the Local GPS Head from other radiating sources. Excessive RF energy can degrade the Local GPS Head’s ability to observe the GPS satellites. The Local GPS Head receives on the GPS L1 frequency of 1575.42 MHz and incorporates filters to minimize the effects of potential RF interference, however, strong radiants can overwhelm the filters, thus degrading the units reception capability. The Local GPS Head is rated for ambient air temperatures in the range -40 to +50 degrees C, and has ratings for humidity, shock, waterproofing, UV light resistance, vibrations, salt, fog, ESD, EMI, and altitude. An RF gain of between +10 dB and +26 dB should be provided to the Local GPS receiver antenna input. The GPS antenna supplied in the CGDSGPSKITF4NM50 kit provides a nominal gain of +25 dB. The total signal loss from the CGDSGPSKITF4NM50 antenna output and Local GPS antenna input must be less than 15 dB at 1.575 GHz. 68P09277A59-5 3-11 Draft OCT 2006 Ethernet Cable Chapter 3: Cable Descriptions Ethernet Cable ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Objective This section contains general information on the Ethernet Cabling.

The colors are matched to the RF Head DC power cables. The colors are as follows: • RFU 1 = RED • RFU 2 = BLUE • RFU 3 = YELLOW • RFU 4 = GREEN Remove the appropriate color sticker and apply it to the underside of the RF Head. Use the appropriate tie-wraps to identify the DC power cables and the Fiber Optic cables. For Example: The first RF Head used would have the power connector identified with the RED sticker, and the power and fiber cables would be tagged with the RED tie-wraps. Prepare the RF Head for hoisting. Attach 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. Proceed to step 5. Prepare the RF Head for hoisting. Attach carabiner to handle of RF Head. Use the block and tackle to carefully hoist the RF Head Assembly up to the tower. Proceed to step 5.

General Grounding Guidelines The site should have had an external ground ring or bus bar being used. The ground ring and bus bar should be an integral part of the structures that will hold the equipment. Reference Grounding Guidelines for Cellular Radio Installations (Motorola part number 68P81150E62) or Appendix C of Standards and Guidelines for Communication Sites. BCU Grounding The BCU should be tied to a single point grounded to the system master ground. All interconnect cables should be in metallic sealtight type conduit or solid shield RF cables. It is recommended that these cables be run in raceways to reduce the loop dimensions of the cable runs. This minimizes the effect of inducted currents caused by the intense electromagnetic field of lightning current. RF Head Grounding All RF cables should be in metallic sealtight type conduit or solid shield RF cables. It is recommended that these cables be run in raceways to reduce the loop dimensions of the cable runs. This minimizes the effect of inducted currents caused by the intense electromagnetic field of lightning current. A ground lug with captive screws is provided on the RF Head to attach the ground wire. DC Power Grounding The DC power cables from the BCU to the RF Head are routed through conduit. The conduit is grounded to the master ground. Antenna Grounding The antenna is grounded through the RF Head. 4-20 68P09277A59-5 Draft OCT 2006
