FSB_050518_01D HUGHES NETWORK SYSTEMS FIELD SERVICE BULLETIN SUBJECT: HNS Broadband requirements for RG-6 and FSB NUMBER: 050518_01D RG-11 IFL cable connectors, Ground Blocks and FSB ISSUE DATE: 05/18/05 Ground Block location SUBMITTED BY: M. Horne , D. Ricker APPROVED BY: CHANGE TO BE IMPLEMENTED BY: AUTHORIZED HUGHES REPRESENTATIVE CUSTOMER ⌧ DOCUMENTATION AFFECTED: HNS Satellite Installation Guides , Training Documentation and Web Sites CATEGORY: HARDWARE ⌧ FIRMWARE SOFTWARE OTHER EFFECTIVE DATE: 05/20/08 IMPLEMENT: ⌧ IMMEDIATELY NEXT SERVICE CALL OTHER COMMENTS: HNS requires that installation and service techs use HNS approved connectors, ground blocks, cable and weatherproofing methods when installing or servicing HNS broadband satellite systems that use RG-6 or RG-11 coaxial (IFL) cables. MANDATORY - All F-connectors that are not installed indoors, must be filled with dielectric grease before connecting them to the radio or ground block. Radio F-Connectors must also be tightened to 22 in/lb and wrapped with a weatherproof tape such as MOCAP or GB Electronics silicone tape. This FSB provides a list of HNS approved components to be used during the installation and servicing of all HNS products except for those listed in the Note immediately below. Note: PES, QDS, TES and DW2000 (MMV) products installed in compliance with FSB1057, FSB1062, FSB 1084, and FSB 1196 are not required to be changed as a result of this FSB. • Where required, systems must be installed in accordance with local codes.The ground requirements in this document are based upon Articles 90.3, 250, 800, 810, and 820 of the NEC. Revision D changes to this FSB 1. A separate ground wire is always required from the antenna canister to either a. The ground block and then to an approved ground point. See Figure 12 b. Directly from the canister to an approved ground point. See Figure 13 2. Connectors installed indoors or inside a weather resistant closure do not need weatherproof tape. 3. A separate ground wire to the radio assembly is not required since the radio assembly is grounded through the metallic shield of the coaxial cable. Reference NEC Article 820.103 4. Do not ground antenna or Ground Block to equipment enclosures such as HVAC cutoff switches. 1 FSB_050518_01D MATERIALS REQUIRED • Compression F connectors from the HNS approved list in Table 1 • Universal compression connector tool. Such as the Sargent 9000US • Cable Prep Tool (Cable stripper used to remove the cable jacket and dielectric to the required length) • Ground Blocks that are UL listed and rated for 2.0 GHz or higher from the HNS approved list in Table 1 • Ground Wire - Minimum 14 AWG green insulated copper or 17 AWG copper clad steel or bronze. Ground wire that is not molded into the jacket of the coax cable must be covered with green insulation. NOTE: 17 AWG Copper-clad steel wire is molded into the jacket of some coaxial cable. This simplifies the grounding of the satellite antenna by eliminating the need to run a separate ground wire from the antenna to the ground block. • UL Listed lugs or clamps to connect to the building ground. I.E. I- Beam clamps & Meter- Meter Pan Bonding Clamps. • Ring lug ground terminals with crimp tools or ground lugs. • A Torque wrench to tighten outdoor connections to 22 in/lb. Such as the Ripley TW-207-AH/B. • Dielectric grease from the HNS-approved list in Table 1 • Self-fusing tape such as Mocap or GB Electronics silicone tape. • Weather resistant enclosure such as North American Cable Equipment 11-MSE-GY-S or Perfect Vision PVCB1GRY. • IFL cable must be from the HNS approved list, UL listed, with a copper center conductor & swept to 2.0 GHz or higher . KU band DW& HN products - Refer to FSB_060316_01 for more information on approved IFL cables. KA band Spaceway products - Refer to FSB _080202_01 for more information on approved IFL cables. 2 FSB_050518_01D ACTION REQUIRED. A. Installation of Connectors, IFL Cables, and Grounding must meet the following requirements. 1. All outdoor F-connectors, must be filled with dielectric grease before connecting them to the radio or ground block. Radio connectors must also be wrapped with a weatherproof tape such as MOCAP or GB Electronics silicone tape.(Figure 2) NOTE: Connectors installed indoors or in a weather resistant enclosure, do not need to be wrapped. B. 2. Tighten Radio & ground block connectors to 22 in./lb. with a torque wrench such as the Ripley TW 207-AH-B CAUTION: Do not wrench tighten Indoor Unit Connectors. Finger tighten only, snug with no play. 3. IFL cable splices are not allowed outdoors except as an emergency measure to restore service. Any outdoor splice must be filled with dielectric grease, wrench tightened and sealed with weatherproof tape. 4. Install the ground block inside the building whenever possible, as close as practicable to the POE. 5. If the ground block must be installed outdoors it must be inside a weather resistant enclosure. Antenna Grounding - NEC Articles 90.3 & 810 1. Use one of the accepted methods of attaching the ground wire to the Antenna Canister Elevation Plate. • Double nut ¼” X1” bolt through the elevation slot of the canister assy with ground wire fully wrapped clockwise around the bolt. • Double nut ¼” X1” bolt through the elevation slot of the canister assy with properly crimped Ring lug terminal. • C. Connect the opposite end of the ground wire to either the coaxial cable ground block (Figure 3) which is connected to an approved ground point or directly to an approved ground point which is at the same ground potential as the ground block Radio and IFL Coaxial Cable Grounding - NEC Article 820 NOTE: It is not necessary to attach a separate ground wire to the radio assembly since it is grounded through the coaxial cable. 820.103 - Unpowered equipment and enclosures or equipment powered by the coaxial cable shall be considered grounded where connected to the metallic cable shield. 1. The IFL Coaxial Cable must be connected to the radio assembly 2. The IFL Coaxial Cable must be connected to an HNS approved ground block as close as practicable to the building POE. 3. The ground block must be connected to an approved building ground point using a listed grounding clamp or lug. NOTE: In single- and two-family dwellings, the grounding conductor from the ground block to the building ground shall not exceed 6m (20ft) in length. Exception - In commercial and apartment buildings, 20 feet limitation is recommended but not specified in the NEC because such a length limitation may not be practicable. 3 FSB_050518_01D DEFINITIONS: Point of Entrance (POE) – Defined in Article 820.2 of the NEC. The point within a building at which the cable emerges from an external wall, a concrete floor slab, a rigid metal conduit or an intermediate metal conduit that is grounded to an electrode. Ground Electrode / “Ground Point” – Based upon Articles 250 , 810.21 (F), and 820.100 (B) of the NEC. Nearest accessible location on the following: • Grounded Structural Steel Member (Figure 6) – Normally found in commercial buildings. You can usually verify that the structural steel is grounded by looking for a large grounding conductor attached to a steel beam or column near the main service panel where the power enters the building. • Service Equipment Enclosure (Figure 7 & 8) – Commercial and Residential buildings. The outside of the breaker panel or meter box wher the servie enters the building. Connecting the ground wire to the Service Equipment Enclosure must not damage or change the integrity of the enclosure. • Grounded Interior Metal Water Pipe (Figure 4) – The ground wire must be connected to a point within 5 feet of where the water service enters the building. (Exception – Industrial, commercial, and institutional buildings where conditions of maintenance or supervision ensure that only qualified personnel service the installation, interior metal water piping located more than 5 feet from the point of entrance can be used as part of the grounding electrode system, provided that the entire length, other than short sections passing through walls floors or ceilings, is exposed.) • Metallic Power Service Raceway (Figure 9 & 10) – The metal conduit / raceway providing power to the main service panel. • Building Ground Conductor (Figure 11) - The main ground conductor or the ground electrode of a building’s disconnecting means (the ground electrode (wire) that is attached to main service panel or disconnect switch). 4 FSB_050518_01D Figure 1 Double nut and washers on bolt Double nut and washers on bolt • • Accepted methods of attaching ground wire to the Antenna Canister Connections must be tight and secure with no play or movement. Double nut and Bolt through the elevation slot with ground wire fully wrapped clockwise around the bolt. Listed ring lug terminal for the size wire being used and crimped with the correct crimp tool. (No channel locks or pliers) Figure 2b Figure 2a All connectors that are not installed indoors MUST be filled with Dielectric Grease before they are connected to the radio or Ground Block Properly weather proofed Radio Coax Connections NOTE: A separate ground wire to the radio ground screw is not required since the radio is grounded through the metallic shield of the coaxial cable.
