If grounding is provided through the grounding conductor and service conductors, no additional grounding is required. In environments where ac grounding conductors are not available, a separate bonding conductor is required. If a separate bonding conductor is required, ground the ac power supply as follows:
1. Use a 2hole lug to connect a No. 16 AWG ground wire to the ground terminals on the front of the power supply. See figure 3-8. AC power supply hb052 Ground terminals Figure 3-8 Ground terminals on ac power supply 2. Connect the other end of the ground wire to the rack ground bar. If the IDU chassis is not rack mounted, connect the ground wire to a ground point such as a water pipe or building steel. 10271440001 Revision D RT installation Installing indoor RT equipment 311 Connecting ac power WARNING The IDU chassis must be solidly bonded to a lowimpedance ground (earth) source. To avoid the risk of electric shock and/or equipment damage, do not apply power to the IDU chassis without a ground reference. CAUTION If the ODU and lightning arrestor are not connected to the IFL, do not power on the IDU chassis without first making sure the IFL is not connected to the IDU chassis. Failure to observe this instruction could result in damage to the equipment. To connect ac power:
1. Measure the voltage level of the power source to make sure it can accommodate the total IDU and ODU power requirements.
(The IDU supplies power to the ODU through the IFL.) If the voltage level cannot accommodate the IDU and ODU, the power source must be upgraded before you can proceed. 2. Connect the power cable to the IEC320C13 connector on the power supply. 3. Route and secure the cable to avoid physical damage. 4. Connect the plug end of the cable to a dedicated ac power source. Important: In the United States, acpower IDU chassis must be connected to a dedicated power circuit with a 15ampere singlepole breaker. The circuit must not include unrelated equipment. 312 Installing indoor RT equipment RT installation 10271440001 Revision D DC power supply Figure 3-9 shows an IDU chassis with a dc power supply. A power cable is not supplied with the dc IDU chassis because cable requirements vary, depending on where the chassis will be used. The power input requirement for the dc power supply (and dc portion of the dual ac or dc power supply) is 42 to 56 Vdc. DC power supply hb050 Figure 3-9 DC power supply Label on dc power supply A label on the dc power supply advises:

Using two or more people for this task will save considerable time. Figure 4-1 Hoisting materials to the installation location T0006060 WARNING If you need to hoist materials to the installation location, observe these precautions to avoid personal injury:
Use a rope strong enough to support all of the materials that need to be hoisted. Never stand under the rope while materials are being hoisted. Hoist one concrete block at a time. Pass the rope through the center hole of each concrete block. If you use the hole on either end, the end can break off, allowing the concrete block to fall. Be advised that the contents of the mount kit can fall through the end of the box if the box is tiltedespecially if the box has been damaged. Use a back brace. If possible, do not hoist the ODU transceiver and antenna on a rope. If possible, carry these components in a backpack or padded bag. 42 Installing IFL cables RT installation 10271440001 Revision D 4.2 IFL cable specifications The intrafacility (IFL) cable specified for AIReach Broadband installations is a Type 3 VSAT coaxial cable, HNS 10108120001

For additional specifications, see the Hub and Remote Terminal Site Preparation Guide. The following Underwriters Laboratories (UL) requirement applies to the IFL cable:
The IFL cable must be installed in a metal conduit and grounded according to NEC article 80040. If the IFL cable will not be installed in a metal conduit, the cable must be a plenum cable, UL/C(UL) approved, with a CMR rating (or higher). For specific grounding instructions, see Grounding the lightning arrestor in section 4.8. Refer also to the grounding guidelines included in the Hub and Remote Terminal Site Preparation Guide. 10271440001 Revision D RT installation Installing IFL cables 43 4.3 Overview: IFL plan IFL

Determine the IFL cable route, from ODU to IDU. Consider the guidelines below. Every building and rooftop is unique; for this reason, some of these guidelines may not apply to your installation:
The most important considerations are the ODU and IDU locations and the building entry point. The entry point should be as close as possible to the ODU. Refer to the RT rooftop drawings. (See also page 53.) The maximum IFL cable length is 1000 feet (305 meters). Where possible, use existing conduit. You must use a pull box to facilitate pulling cables through conduits if routing cable through bends totaling more than 360. If existing conduits can not be used and the cable will be exposed, refer to building codes to determine proper cable insulation type. For example, plenum rated cable must be used if cable will be run above suspended ceilings. If you are installing the IFL cable(s) inside a conduit that contains power cables, you must use plenumrated cable. Look for cable routes that will be easily accessible, such as stacked telco closets etc. Older buildings may not have stacked telco closets. You may have to route the cable back and forth, from one side of the building to the other. Never run the IFL cable across corrugated roofing. Run the cable in the corrugation trough:

Go to the roof. 2. Determine where the IFL cable will penetrate the roof. Refer to the RT rooftop drawings. Before you drill, consider these guidelines:
Important: Do not penetrate any part of the building structure without first making sure you have the explicit permission of the customer and building owner. Horizontal penetration is preferable to vertical penetration.
(A horizontal hole is less likely to leak.) Take care not to destroy cabling or wiring under the roof or inside the wall. Round penetration holes are preferred over square holes.
(They are easier to make and seal.) 3. Drill a 2inch (51millimeter) diameter hole at the building penetration point. Building surface Building penetration point 2 inches

The lightning arrestor is attached to the penetration sleeve after cable installation. 1. Use twelve screws to attach the RT penetration sleeve
(sleeve and coupling) to the building surface at the building penetration point. See figure 4-4. The type of screw used depends on the roof thickness and surface composition. The screws must hold the sleeve securely. Note: If space is limited, use a 90 sweep, as illustrated in figure 4-4. Sweep Penetration sleeve with sweep Screws

Weatherproof the penetration sleeve by applying silicone caulk or other weatherproofing material to the bolt hole areas and the surface of the sleeve plate. Note: Silicone caulk may not be suitable for certain types of roofs. 10271440001 Revision D RT installation Installing IFL cables 47 4.7 Installing the IFL cable inside the building You install the IFL cable in two segments, as shown in figure 4-2
(page 44). To install the first cable segmentfrom the IDU chassis location to the lightning arrestorfollow the instructions and guidelines below. Because every building has unique features, it is not possible to give exact instructions. 1. Measure the cable run length from the IDU chassis location to the lightning arrestor location (IFL building entry point). Allow for routing around obstacles and a service loop
(excess cable, in case there is any reason to later cut and reterminate the cable). 2. Run the cable from the IDU chassis location, through an existing conduit if possible, through the RT penetration sleeve (figure 4-4), to the lightning arrestor location. Use a stand so the cable spool spins freely as it is pulled. Leave a service loop. CAUTION Avoid making sharp bends in the IFL cable. The minimum bend radius for IFL cable is 2 inches (51 millimeters). Sharper bends may cause permanent damage to the cable. 3. Cut the cable at the IDU chassis location and at the 4. lightning arrestor. Important: Cut the cable 2 feet (0.6 meters) beyond the lightning arrestor location (building penetration point). Terminate the cable end at the IDU chassis location with an Ntype connector. For detailed instructions for connecting an N connector, see appendix C. Important: Sound IFL cable connections are critical for proper operation of the AIReach Broadband system. Therefore, be very careful in terminating the cable. Refer to the detailed instructions in appendix C if necessary. Attach N connectors after you route and install the cable, not before. Note: The IFL cable installation is completed in section 4.9. 48 Installing IFL cables RT installation 10271440001 Revision D 4.8 Installing the RT lightning arrestor All AIReach Broadband IFL cables must connect to a grounded lightning arrestor (provided by HNS) at the building penetration point, as shown in figure 4-2 (page 44) and explained in this section. WARNING To help avoid death, injury, or damage from a lightning strike, you must install a lightning arrestor where the IFL enters the building. Figure 4-5 identifies the components of a typical RT lightning arrestor. The design illustrated here (see also figure 4-6) can accommodate one or two IFL cables for up to two RTs.

1. Connect one end of the ground cable (No. 6 AWG or greater, green) to the lightning arrestor ground bar, as shown in figure 4-10. Ground bar Single-hole compression lug Ground cable No. 6 AWG or greater To ground point rt051 Figure 4-10 RT lightning arrestor grounding connections 2. Route the ground cable to the ground point. When routing the ground cable, you must:
Secure the ground cable at 5foot (1.5meter) intervals. Keep the ground cable at least 3 feet (0.9 meters) away from nongrounded metal objects. Make sure all bends in the cable have a sweeping radius of more than 8 inches (20.3 centimeters). 3. Connect the RT lightning arrestor to the same ground
(reference) point as the ODU ground. See section 6.10. 4. Apply antioxidant (HNS 90082240002) to each ground lug. 5. Apply 1/2inch (13millimeter) heat shrink tubing (HNS 90074880005) to each ground lug after the connection is complete. Important: You must slip the heat shrink onto the cable before you make the connections. 412 Installing IFL cables RT installation 10271440001 Revision D 4.9 Installing the IFL cable on the roof Connecting to the lightning arrestor To install the second IFL cable segmentfrom the lightning arrestor to the ODUfollow the instructions and guidelines below. Because every rooftop has unique features, it is not possible to give exact instructions. Connect the IFL to the lightning arrestor as follows:
1. Measure the cable run length from the lightning arrestor to the ODU. Allow for routing around obstacles and a service loop (excess cable, in case there is any reason to later cut and reterminate the cable). 2. Run the cable from the lightning arrestor to the ODU location, and leave enough cable for a service loop. For now, you must leave the cable unconnected because the ODU is not installed yet. You will connect the IFL to the ODU later, after the ODU is installed. CAUTION Avoid making sharp bends in the IFL cable. The minimum bend radius for IFL cable is 2 inches (51 millimeters). Sharper bends may cause permanent damage to the cable. 3. Cut the cable at the lightning arrestor and at the ODU. 4. Terminate both ends of the cable segment with N connectors. For detailed instructions for connecting N connectors, see appendix C. 10271440001 Revision D RT installation Installing IFL cables 413 5. Connect the IFL cable to the RF arrestor, as shown in figure 4-11. You connect the other end of the cable to the ODU later, after you install the ODU. Ground wire To ODU IFL N connector N connector RF arrestor T0009013 Figure 4-11 Connecting the IFL to the RF arrestor Do not apply permanent weatherproofing until the RT has been commissioned and tested. If the weather is wet or windy, a temporary tape seal is recommended. Weatherproofing is covered in section 8.1. Test the IFL cable and connectors as follows:
1. Check each connector: Use a multimeter or continuity tester to check for continuity (a short circuit) between the center conductor and the connector body (outer shell). If the meter or tester does not indicate an open (no connection), the connector or cable is defective and must be replaced. 2. Check the connectors and cable:
a. Using a small jumper cable, attach a jumper clip to the center conductor of the connector on one end of the cable. b. Attach the other end of the jumper to the connector c. body, so the center conductor and connector body make electrical contact. At the other end of the cable (at the IDU location), use a multimeter to measure the resistance between the center conductor and connector. Resistance should be less than 10 ohms. If it is greater than that find and correct the problem. Testing the IFL cable 414 Installing IFL cables RT installation 10271440001 Revision D Finishing the cable installation After running the cable, finish the cable installation as follows:
1. Support the cable above the roof surface with a cable trough or wood blocks approximately 4 inches by 4 inches by 4 inches (10 centimeters by 10 centimeters by 10 centimeters):
hb010 2. 3. 4. Tie down cable runs on the roof and at the IDU location with tiewraps. Seal the IFL rooftop entry point with weatherproofing caulk. Label both ends of the IFL cable to identify the cable in an appropriate manner. This is especially important if you are installing multiple IFL cables. (To order IFL labels, request HNS part number 90053280055.) 10271440001 Revision D RT installation Installing IFL cables 415 I N O T A L L A T S N I T R Chapter 5 Installing mast mounts This chapter includes:

In some cases, a different type of mast mount may be used, or an existing structure may be used. The mount supports the mast in a vertical or horizontal position, and the ODU is mounted on the mast, as shown in figure 5-1. Figure 5-1 Mast mount supporting mast and ODU rt009 52 Installing mast mounts RT installation 10271440001 Revision D 5.2 ODU location 5.3 Roof types 5.4 Mast mount types Site preparation personnel specify the ODU location as part of preparing the RT rooftop drawing. 1. Use the RT rooftop drawing to determine where to install the mount (at the ODU location) and locate the IFL entry point. 2. Make sure the roof penetration or entry point for the IFL is suitable. Important: The location(s) used for ODU installation must meet the requirements listed in the Hub and Remote Terminal Site Preparation Guide. Key considerations include:
Line of sight Distance from HT IFL entry location Sources of interference Safety Ground point location Access Security For details, see the Site Preparation Guide. Many roof types are suitable for AIReach Broadband ODU installations. Mount installation procedures for the following common roof types are described later in this chapter:
Rubber cap sheet/ glued rubber cap sheet Loose gravel on rubber cap sheet Corrugated metal The roof type is a factor in the type of mast mount selected. Also, some mount installation steps may be different, depending on the roof type. The following options are available for mounting a mast to support the ODU:
Nonpenetrating roof mount This mount, essentially a flat platform assembled from a kit, is suitable for most applications. It can be used on various flat roof types. For details, see section 5.5. Existing structure An existing structure such as an antenna tower can be used as a mast, or a mast can be mounted to the structure, if the structure meets the requirements given in the Hub and Remote Terminal Site Preparation Guide. 10271440001 Revision D RT installation Installing mast mounts 53 5.5 Standard nonpenetrating mount The standard nonpenetrating roof mount, HNS 92003750001, is a flat, metalframe mount assembled from a kit. It requires a 6.5by6.5foot space (1.98 by 1.98 meters) and includes a 7foot
(2.1meter) mast. You install the mount on a rubber pad; concrete blocks are added for ballast. The standard mount can be used on a variety of flat roof types, as detailed below. Instructions are given below for various types of roofs. See also the manufacturers instructions, which are included in the mount shipping carton. Flat roof rubber sheet
(with or without gravel) Most flat roofs are topped with:
Glued rubber cap sheet or Rubber cap sheet with gravel Follow these instructions for either type of roof:
1. If the cap sheet is covered with gravel, use a push broom or snow shovel to clear the gravel from the area where the mount will be installed, as shown in figure 5-2. T0006061 Figure 5-2 Clearing gravel from the installation location 2.

Place the concrete blocks on the mount so they are evenly spaced, with the ends of each block anchoring both the inner and outer base angles, as shown in figure 5-8. Figure 5-8 Proper placement of concrete blocks on the mount T0009060 10. When the mount installation is complete, if the roof is covered with gravel, replace gravel up to the outside edges of the mount. See figure 5-8. Do not replace gravel in the area inside the mount base. Leave the rubber pad exposed. Corrugated metal This section explains how to install the standard nonpenetrating roof mount on a corrugated metal roof. Special requirements:
Pressure treated lumber, as specified in step 1 below, and Twelve 1inchlong (2.5centimeter) lag bolts. 1. Obtain five pieces of pressure treated lumber, each 4 inches by 4 inches by 8 feet long (10 centimeters by 10 centimeters by 2.44 meters long). Important: Select an area of the roof that is supported by a metal Ibeam to install the mount. 2. 3. Cut the rubber pad into strips 4 inches wide by 8 feet long
(10 centimeters wide by 2.44 meters long). 4. Use 5penny shingle nails to nail one strip of rubber pad to one surface of each piece of lumber. See figure 5-9. 10271440001 Revision D RT installation Installing mast mounts 59 5. Lay out the 4 x 4s, as shown in figure 5-9, so that each piece is:
- In the recessed portion of the roof
- Parallel to the raised seams
- Equally spaced to support the mast, mount braces and sides, and concrete blocks, as shown in figure 5-9. Lay the lumber with the pad side down, so that the pad is between the roof and the lumber. Cinder block Mast mount End view Wood

Make sure the mount is evenly positioned on the 4 x 4s, then use lag bolts to bolt the mount to the 4 x 4s. Install the bolts through the holes in the mounts outer frame and into the wood. Use one bolt at each end of each piece of lumber (as shown in figure 5-9). Use one bolt at the center of each remaining side of the mount. 8. Add the required number of concrete blocks for ballast. See steps 8 and 9 on page 58. 510 Installing mast mounts RT installation 10271440001 Revision D 5.6 Using existing structures as ODU mounts In some cases, you may be able to mount an ODU to an existing structure, such as a tower built to support communications antennas. The key factors for determining if an existing structure can be used as mast are that the structure must:
Be securely attached to the building (and capable of sustaining specified wind loadings). Have an outside diameter of 2.0 to 4.5 inches. Meet line of sight (LOS) requirements. Important: In addition to these criteria, the structure must also meet other requirements listed in the Hub and Remote Terminal Site Preparation Guide. 10271440001 Revision D RT installation Installing mast mounts 511 I N O T A L L A T S N I T R Chapter 6 Installing ODUs This chapter explains how to install RT ODUs.

DANGER Do not work on a ladder or roof without first reading the safety warnings on page x of this manual. Failure to observe these warnings could result in personal injury or death. WARNING Potential radio frequency (RF) hazard:
Keep away from the front of the outdoor unit (ODU) antenna while the ODU is operating. Note that you cannot tell from outward appearance whether the ODU is operating or not. Be careful with respect to the ODU you are installing and ODUs that may already be operating in the installation area. Failure to observe these warnings could result in injury to eyes or other personal injury. 10271440001 Revision D RT installation Installing ODUs 63 Prerequisites Before you can install and commission the outdoor RT equipment:
The hub must be installed and operational. The RT ESN (electronic serial number) must be entered in the EMS database. The mast must be installed. The mast must have an outside diameter of 2.0 to 4.5 inches (5.5 to 11.4 centimeters) and must be securely mounted in a vertical or horizontal position. If the mast is not installed, you will need to install it before you proceed. For additional details concerning the mast, see the AIReach Broadband Hub and Remote Terminal Site Preparation Guide. Before starting, make sure you have:
Antenna mount Antenna Transceiver 3/8inch torque wrench with 13millimeter deep socket 5/32inch (4millimeter) torque hex key wrench Unpack the ODU transceiver and antenna before going up to the roof. Carry the transceiver and antenna to the roofin separate tripsin a backpack or padded bag. Make sure the transceiver or antenna is secured in the backpack or bag. 6.2 Transporting the ODU to the roof 64 Installing ODUs RT installation 10271440001 Revision D 6.3 Preparing to install the antenna mount The antenna mount (HNS 10290560005) is shipped fully assembled. Figure 6-3 shows an exploded view to show all the parts. However, you do not need to take the mount apart to install it, unless you need to reverse the mast clamp.

Parts of the mast interface move to allow these adjustments. 10271440001 Revision D RT installation Installing ODUs 65 Important: To correctly install the antenna mount, read and carefully follow all instructions in this section (6.3) through section 6.7. Prepare the mount for installation:
1. Turn the fine azimuth adjuster as necessary to position the clevis (barrel) approximately in the middle of the threaded part of the adjuster. See figure 6-4. This step ensures that you will be able to adjust the adjuster as necessary in either direction. Do not turn the nut behind the block that holds the fine azimuth adjuster. Fine elevation adjuster Fine azimuth adjuster Begin with clevis approximately in the middle of the adjuster. Turn to adjust. Do not turn. Clevis T0009020 Figure 6-4 Fine azimuth and elevation adjusters 2. Turn the fine elevation adjuster as necessary to position the clevis approximately in the middle of the threaded part of the adjuster. See figure 6-4. Do not turn the nut behind the block that holds the fine elevation adjuster. 66 Installing ODUs RT installation 10271440001 Revision D ODU height Determine (approximately) how high on the mast to install the mount:
1. Determine the approximate desired antenna installation height:
The ODU/antenna must be installed in line of sight with the hub terminal (HT), with no obstructions. As a general rule, install the RT ODU as high as possible on the mast to avoid obstructions, unless the work order or RF survey specifies the ODU height. 2. Refer to figure 6-5 for the mount position relative to the position of the (not yet installed) antenna. As shown in this illustration, when the antenna is installed (later), the antenna vertical center is at the same height as the vertical center of the mount. Mast The antenna is not installed yet. It is shown here to illustrate that the vertical centers of the antenna mount and the antenna are at the same height. T0009022 Antenna
(front) Antenna center Figure 6-5 Antenna mount height relative to desired antenna height 10271440001 Revision D RT installation Installing ODUs 67 6.4 Installing the antenna mount Follow the steps below to install the antenna mount. 1. Determine which side of the mast clamp to use:
Use this side against the mast if the less than mast outside diameter is 3.5 inches (8.9 centimeters)
. Mast clamp Use this side against the mast if the mast outside diameter is 3.5 inches
(8.9 centimeters) or larger. T0009024 2. One side of the mast clamp has two openend bolt holes that allow the long bolts that are attached to the mast interface to swing in or out. See figure 6-6. At the side of the mount where the two openend bolt holes are, swing the two bolts outward so you can open the mount enough to place it around the mast. Open-end bolt hole T0009032 Figure 6-6 Opening the mount 68 Installing ODUs RT installation 10271440001 Revision D Place the mount on the mast, as shown in figure 6-7. The fine azimuth adjuster must be on the side of the mount opposite the HT direction, as illustrated in figure 6-7. This allows you to make azimuth and elevation adjustments from behind the antenna, so you can stay out of the beam area. To get the azimuth adjuster on the side opposite the HT direction, you may have to turn the entire mount 180, depending on whether the ODU will be mounted to the left or right of the mast.
(If you are facing the mast interfaceas a referenceit doesnt matter whether the mount swings open to the right or to the left, as long as the azimuth adjuster is opposite the HT direction.) Swing the clamp toward the interface until you can capture the clamp by swiveling the freeswinging bolts into the two slots in the clamp, as shown in figure 6-7. 3. 4. 2 1 1. Swing clamp toward interface. 2. Swivel bolt into slot. Mast clamp T0009025 HT direction Fine azimuth adjuster Figure 6-7 Installing the antenna mount 5. Finger tighten the four mast clamp nuts. Tighten the nuts enough to hold the mount to the mast, but leave them loose enough so you can smoothly pivot the mast interface and mast clamp around the mast to permit coarse azimuth adjustment.
(You fully tighten the mast clamp nuts later.) 10271440001 Revision D RT installation Installing ODUs 69 6.5 Attaching the antenna to the mount Follow the instructions in this section to attach the antenna to the mount.

See figure 6-18. 618 Installing ODUs RT installation 10271440001 Revision D 6.8 Installing a mechanical attenuator You must use a mechanical attenuator (figure 6-19) if:
The RT is within 328 feet to 1,312 feet (100 to 400 meters) of the HT. The RT pointing voltage, obtained from a voltmeter, exceeds 4.1 volts. The installation work order instructs you to use it. If none of these applies, go on to section 6.9. rt006 Figure 6-19 Mechanical attenuator WARNING To avoid the risk of electric shock and exposure to potentially harmful radio frequency (RF) waves, make sure the IDU is turned off, if already installed, before installing the mechanical attenuator. Failure to observe these warnings could result in personal injury. Attenuator size Use the attenuator size (in decibels) specified in the installation work order and/or Site Data Record.

1. Locate the circular waveguide on the rear of the antenna. See figure 6-20. Insert the mechanical attenuator in the circular waveguide, as shown in figure 6-20. Important: Do not fully insert the mechanical attenuator. Ensure that part of the attenuator is exposed so it can be removed if necessary. T0009015 Insert attenuator here. Attenuator Close-up of waveguide Figure 6-20 Installing the mechanical attenuator CAUTION Do not allow dirt, dust, moisture, or other contaminants to enter the waveguide. If you have installed an attenuator, make a note of its size (for example, 20 dB). You will need this information when you commission the RT. 620 Installing ODUs RT installation 10271440001 Revision D 6.9 Attaching the transceiver to the antenna Follow these steps to attach the transceiver to the antenna:
1. Remove the plastic plug from the antenna waveguide and the plastic cap from the transceiver coupling. CAUTION Always keep the waveguide and coupling plugs in place when the transceiver is detached from the antenna, to prevent contamination. 2. Position the transceiver so its four mounting bolts are aligned with the four grooves on the antenna flange, as shown in figure 6-21. Antenna Transceiver T0009010 Waveguide Antenna flange Flange groove Mounting bolt
(Attached to transceiver) Figure 6-21 Aligning the transceiver mounting bolts 10271440001 Revision D RT installation Installing ODUs 621 3. Rotate the transceiver, making sure the transceivers mounting bolts slide into the grooves in the antenna flange.
(The direction of rotation depends on the orientation of the antenna bracketto the right or left.) If the mounting bolts will not slide into the grooves, loosen the bolts. See figure 6-22. Rotate transceiver to slide bolts into grooves.
(Rotation direction depends on orientation of antenna bracket to right or left.) Mounting bolts must be fully inserted in flange grooves. T0009011 Boresight Figure 6-22 Rotating the mounting bolts into the grooves Fully tighten the transceiver mounting bolts. 4. 5. After tightening the transceiver, look through the boresight to make sure the antenna is still pointed at the HT. The ODU is now installed, but still needs to be grounded, connected to the IFL, and electronically pointed. 622 Installing ODUs RT installation 10271440001 Revision D 6.10 Grounding the ODU Grounding the ODU requires several connections, as shown in figure 6-23. In making the ground connections, follow these practices:
For all ODU ground connections, use compression connectors (such as compression lugs or compression clamps). For all threaded ground connections, use a flat washer and lock washer (with the lock washer next to the nut). Ground the ODU as follows:
1. Connect one end of the ground cable (No. 6 AWG or greater, green) to the ODU ground connector, which is shown in figure 6-23. 2. Connect the ground cable to a bolted joint on the mast mount. Important: For this connection, strip the cable but do not cut it. See figure 6-23. The cable continues from the bolted joint to the ground point. 3. Connect the ground cable to a suitable ground point on the rooftop. The best ground point for the ODU is an earthreferenced roof ring conductor that follows the perimeter of the building, constructed according to the requirements of NFPA 780 or a similar regulatory code. However, such a conductor is not always present. Other alternatives are acceptable, as long as they comply with the grounding requirements detailed in the Hub and Remote Terminal Site Preparation Guide. Building steel can also be used as a ground point. However, before using building steel, verify that the steel structure is electrically continuous throughout the entire building and that it is properly connected to earth ground. For detailed grounding requirements, see the Hub and Remote Terminal Site Preparation Guide. 4. Apply antioxidant (HNS 90082240002) to each ground lug (points 1, 2, and 3 in figure 6-23). 5. Apply 1/2inch (13millimeter) heat shrink tubing (HNS 90074880005) to each ground lug after the connection is complete. Important: You must slip the heat shrink onto the cable before you make the connections. Note: A resistance of less than 5 ohms is desirable from the ODU to earth, including the earth field. 10271440001 Revision D RT installation Installing ODUs 623 1.

The ODU ground and IFL lightning arrestor must both be bonded to the same ground (reference) point. 6.11 Connecting the IFL to the ODU Connect the IFL to the ODU as shown in figure 6-24. Rear view N connector Ground wire T0009014 IFL Figure 6-24 Connecting the IFL to the ODU Do not apply permanent weatherproofing until the RT has been commissioned and tested. If the weather is wet or windy, a temporary tape seal is recommended. Weatherproofing is covered in section 8.1. At this point, antenna installation is complete, and the antenna is visually pointed. Later, when you commission the RT, you will use a voltmeter to electronically point the antenna as accurately as possible. 10271440001 Revision D RT installation Installing ODUs 625 I N O T A L L A T S N I T R Chapter 7 Commissioning the RT This chapter includes:

Safety warnings Observe these safety warnings while commissioning RTs:
DANGER Do not work on a ladder or roof without first reading the safety warnings on page x of this manual. Failure to observe these warnings could result in personal injury or death. WARNING Potential radio frequency (RF) hazard:
Keep away from the front of the outdoor unit (ODU) antenna while the ODU is operating. Note that you cannot tell from outward appearance whether the ODU is operating or not. Be careful with respect to the ODU you are installing and ODUs that may already be operating in the installation area. Failure to observe these warnings could result in injury to eyes or other personal injury. 10271440001 Revision D RT installation Commissioning the RT 71 7.1 Prerequisites for commissioning To ensure successful commissioning, you must verify that the prerequisites listed below have been accomplished. These tasks must all be completed prior to commissioning. If any of them has not been done, make sure they are completed before you proceed with commissioning. The RT ODU, IFL, and IDU must be installed and connected. If you have followed all previous instructions, this prerequisite is satisfied when you connect the IFL to the CCM (IDU), as instructed on page 74. The ODU must be coarsely (approximately) pointed toward the HT, as explained in chapter 6. The Element Management System (EMS) hardware and software must be installed and operational. All physical LAN connections between the RT and EMS must be completed. The EMS database must be loaded and operational. The EMS operator must enter the RT electronic serial number
(ESN) into the EMS database. The RT ESN is printed on a tag attached to the CCM and can also be read from the CCM LCDfrom the Main Menu ESN display. The installer must know the (RT) ODU frequency to be used and the identification number of the HT the RT will communicate with. These are provided by network planning personnel. The hub and HT must be installed and operational. The HT must be properly aligned. The CCM must be installed in the IDU. (SSIs are not required for commissioning.) Note: The RT cannot be located closer than 109 yards (100 meters) from the HT. 72 Commissioning the RT RT installation 10271440001 Revision D Connect the IFL cable to the CCM (IDU):

This section explains how to fine tune the pointing adjustments, using a digital voltmeter. To point the antenna, follow steps 1 through 12 below. Selecting the ODU frequency Before you can point the antenna using the voltmeter, you must first put the IDU into Install mode and select the (RT) ODU frequency, as follows:
1. From the IDU (CCM) LCD Main Menu, select Install mode, and press the ENTER button. Main Menu Install The LCD displays:
Install RT at HT 2. 3. Press ENTER, select No, and press ENTER again. Select Frequency (frequency function) and press ENTER. Install Frequency 4. The LCD displays Freq and a frequency value:
Freq 8B4 5. Scroll to the correct ODU frequency. Scroll up (NEXT) for a higher frequency; scroll down (PREV) for a lower frequency. The frequencies you can select on the bottom line are preset, based on the installed ODU. The correct RT frequency is the same as the HT frequency, except B
(indicating remote), as in 8B4, replaces A. Important: If you do not see the correct frequency on the LCD, you may have installed the wrong ODU for the site
(high band instead of low band, or vice versa). If the wrong ODU is installed, the LCD will not display the correct 78 Commissioning the RT RT installation 10271440001 Revision D Voltmeter pointing and final adjustments frequency as one of the available choices. You will not be able to proceed until the correct ODU is installed. Press ENTER when the LCD shows the correct frequency, for example:
6. Freq Set 8B4 Go to the roof and proceed with steps 7 through 12. While you are pointing the antenna, the LCD shows Freq Acq in Prog (frequency acquisition in progress). When the RT acquiress the HT frequency, the LCD shows Acq Ack: HT 2 (acquisition acknowledgedin this example, frequency acquired from HT 2). Follow these steps to finetune the azimuth and elevation adjustments made when the antenna was installed (sections 6.6 and 6.7). 7. Take the digital voltmeter and torque wrench (with deep socket) to the ODU. 8. Make sure the azimuth and elevation locking nuts on the antenna mount are loosejust loose enough to allow the antenna to rotate (for elevation adjustment) and move in azimuth. These nuts are shown in figure 7-5.

(HNS90074880005) onto the cable, as shown in figure C-2. Heat-shrink tubing Crimp ring Butt-cut cable end hb014 Figure C-2 Slipping the crimp ring and heatshrink tubing onto the cable 4. Use the spinstripping tool (Excelta CX 1781, gold colorcoded) to remove the cable jacket and dielectric, leaving about 7/32 inch (6 millimeters) of the center conductor exposed, as shown in figure C-3. a. Open the stripping jaws of the spinstripping tool enough to allow the cable end to enter the cable barrel fully. (See figure C-3.) b. While holding the cable firmly in the tool and tightly against the cable stop, squeeze the stripper jaws. c. Rotate the tool around the cable two or three times until the outer cable jacket and dielectric are completely cut through, but do not score the center conductor. Rotate the tool in the direction indicated in figure C-3. d. Remove the cutoff end of the cable jacket and dielectric. 10271440001 Revision D RT installation Terminating the IFL cable C3 Gold-colored cable stop Stripper jaws Butt-cut cable end Barrel 1.

- Braid for nicked or broken strands
- Dielectric end for a straight cut
- Center conductor for nicks and a straight cut If you see significant damage to the braid, dielectric, or conductor, you must cut the cable and start over. (Start with step 1.) 10271440001 Revision D RT installation Terminating the IFL cable C5 C.3 Attaching the connector 8. Flare the braid slightly and trim to 7/16 inch (11 millimeters), as shown in figure C-5. 7/16 inch
(11 millimeters) Jacket hb093 Braid Figure C-5 Braid, flared and trimmed 9. Cut approximately 1/4 inch (6 millimeters) of the excess braid so that all braids will be under the crimp ring when the connector is completed. The following steps explain how to attach the IFL (N) connector. The same type of connector is used at both ends. The connector includes a plastic guide pin to protect the dielectric during installation, as shown in figure C-6. Crimp ring Center pin Support shoulder Collar Jam nut Insulating washer Plastic guide pin T0006020 Connector body Figure C-6 IFL (N) connector (HNS 90062840002) Do not remove the plastic guide pin until instructed to do so
(step 4 on page C8). CAUTION Do not install the center pin without the plastic guide pindoing so will damage the dielectric material inside the connector body. C6 Terminating the IFL cable RT installation 10271440001 Revision D To install the cable connector, follow these steps. 1. 2. Place the insulating washer against the dielectric. Push the center pin (with guide pin attached) over the cable center conductor, as shown in figure C-7. Crimp area Center pin Guide pin Crimp flush with washer. Insulating washer T0006021 Figure C-7 Installing the insulator and center pin 3. Use the HCT231 crimp tool (figure C-8) to crimp the center pin flush with the washer, as shown in figure C-7. If the center pin is bent after crimping, cut the cable, restrip it, and attach a new center pin. 0.475 Use the crimp ring This is a later step. setting to crimp but not yet.

Insert guide pin through back of connector body until the cable stops. Connector body Crimp ring Center pin Guide pin Ground socket Center pin inside connector body Recess hb022 2. Slide crimp ring over braid and into recess. 3. Remove and discard guide pin. Figure C-9 Installing the connector body and crimp ring 5. Important: Verify that the center pin aligns flush or within 1/64inch from the ground socket edge. If the pin is not flush or within this range, the connection will probably be faulty. C8 Terminating the IFL cable RT installation 10271440001 Revision D 6. Comb the braid only if the crimp ring will not fit over the shoulder and braid. If the crimp ring fits over the shoulder and braid, skip to step 7). a. Insert a pick or scribe into the braid and carefully comb the strands as shown in figure C-10. Start combing at the cut end. Comb the strands around the entire perimeter. Work backward, from the cut end toward the jacketbut always combing away from the jacket, as shown in figure C-10. Jacket Braid Comb action Direction of travel hb017 Figure C-10 Combing the braid Note: Comb the braid all the way back to the jacket. If part of the braid is uncombed at the jacket end, stretching will cause the jacket and center pin to become loose, resulting in poor conductivity. b. Retrim the braid to 7/16 inches (6 millimeters), as shown in figure C-5. 10271440001 Revision D RT installation Terminating the IFL cable C9 7. While holding the connector assembly together snugly, position the HCT231 crimping tool, at setting 0.475, onto the area shown in figure C-11 and securely crimp the crimp ring into place. CAUTION To avoid damaging the connector body, make sure the crimping tool does not touch the connector jam nut. Crimp hb024 Maximum gap
(exposed braid):
0.03 inch (0.8 millimeter) Best if no gap. Figure C-11 Crimp location Note: If the crimp ring slips and results in a gap greater than 0.03 inch (0.8 millimeter) between the crimp ring and the connector collar, reject the connection. Cut off the connector and start over. C10 Terminating the IFL cable RT installation 10271440001 Revision D C.4 Applying heatshrink tubing Apply the heatshrink tubing as follows:
1. Position the heatshrink tubing near (but not touching) the jam nut, so it covers the crimp ring and a portion of the connector collar, as shown in figure C-12. Heat-shrink tubing Crimp ring Collar Jam nut hb026 Figure C-12 Heatshrink tubing, properly placed for shrinking 2. Using a heat gun, heat-shrink the tubing until it snugly fits around the cable, crimp ring, and part of the connector collar. Point the connector upward. Begin heating at the connector end, and work toward the cable. The adhesive should flow away from the jam nut. CAUTION Do not allow the cable jacket and dielectric to overheat. This can damage the cable and cause cable failure. During heating, the tubing may shift and the adhesive lining may bleed. Make sure the adhesive does not bleed onto the jam nut and damage the connector. To install another N connector, repeat all steps above, beginning with the section Preparing the cable ends (page C3). 10271440001 Revision D RT installation Terminating the IFL cable C11 Index A B Abbreviations (identified), A- 1 Ballast.
