The installation of a TerraStreamer® ESE Terminal combines the best advantages of two systems: the direct path to ground of a conventional lightning protection system, and stateof-the-art ESE technology employed in the TerraStreamer®’s internal design. TerraStreamer® ESE Terminals are designed to react to the rise in the ambient electrical field which is present with approaching thunderstorms, and become active only during storm activity. • The system operates without the need for external power supply or spare parts for standard operation. • To keep the TerraStreamer® ESE Lightning Protection System operating at optimum levels it needs to be maintained and inspected regularly.

The NF C 17-102 standard includes four levels of protection. Protection Radius Additional Levels Level 1+: The ESE system at level of protection 1 is additionally connected to the metal structure or reinforced bars of the buildings used as natural downconductors in addition to the dedicated downconductors included in the ESE system. Connection to the natural downconductors shall be made at roof level and ground level. Upward Streamer TerraStreamer® Rp h Level 1++: The roof is protected at level 1+ with an ESE having a radius of protection reduced by 40% compared to achieve a complete protection of equipments on the roof against direct lightning strikes. 5 Positioning & Height TerraSteamer® ESE Terminal The TerraSteamer® ESE Terminal tip should be at least 2 meters higher than the area that it protects, including antennae, cooling towers, roofs, tanks, etc. If the external installation for a given structure comprises several ESE Terminals these are to be interconnected by a suitable conductor, unless it has to be routed over a structural obstacle (cornice, parapet wall) with a positive or negative level difference in excess of 1.5m (see Fig. A). When ESE Terminals protect open areas such as playing fields, golf courses, swimming pools, camping sites, etc., they should be installed on specific supports such as tower mast, lightning poles, pylons, or any other nearby structures which enable the ESE Terminal to cover the area to be protected. The ESE Terminal height may be increased by means of an elevation mast. If the ESE Terminal is steadied by conductive guy lines, these should be connected at the bottom attaching points to the down conductors by means of suitable conductors. Preferred Installation Points The architectural features favorable to the ESE Terminal installation should be taken into account during the lightning protection system design. Usually, these features are high structural points, such as: • equipment rooms on flat roofs • gables • metal or masonry chimneys ≥ 2m ≥ 2m < 1.5m < 1.5m Fig. A - Positioning & Height 6 Pre-Installation Checklist Determine the best location for ESE Terminal(s), then the mounting method (tower, mast, structure, etc.) and the optimum routing of down conductor(s). Locate area(s) for grounding system installation and determine where the new system will be connected to any existing grounding system and metal bodies of conductance, etc. Verify that all parts and system components are compatible (dissimilar metals not allowed) and in good condition. Review installation plans, structural drawings, site drawings and mast erection instructions. Read this Installation Guide and familiarize yourself with all of the system components and functions. Be sure that all tools and equipment required for system installation are available and in good working order. Follow all industry guidelines and local/site requirements for safety and safety equipment. Important Safety and Other Considerations • • • • • • • If the TerraStreamer® ESE Terminal needs to be erected prior to connection to the grounding system, or immediate connection is not possible, connect the lower end of the down conductor to structural steel reinforcing or other suitable grounding point. Before installation of the grounding system, consult site drawings of underground services so that these are not damaged during installation of the grounding system. Where separate grounding systems exist, i.e.: structure, power, communications and/or lightning protection, they need to be bonded together to form an equipotential ground plane. This will help prevent ground potential differences arising under direct/indirect lightning strikes. Before service ground bonding takes place make sure proper authorization is obtained. Bonding cable must be 70mm2 (2/0AWG) minimum, depending on local standards. It may be necessary to use a grounding bus bar which bonds all grounds to the same potential under transient conditions. All local applicable standards, regulations and requirements necessarily apply. It is the responsibility of the customer/installer to label inspection/test wells or grounding systems to local requirements. Stay clear of any overhead power lines. 7 Ground System Configurations A ground resistance of less than 10Ω is required for proper operation of the TerraStreamer® ESE Terminal. If, due to space constraints or high soil resistivity, it is not possible to readily install a grounding system as recommended, alternate grounding methods and designs shall be considered. In order to meet safety and grounding system resistance requirements, Alltec recommends the installation of a purpose designed and installed grounding system such as the radial (crow’s foot) design or Delta design. Other configurations and materials are allowed, and may be required due to local conditions. NOTE: Alternate grounding methods and designs are allowed by NF C 17-102, and Alltec is capable of designing a grounding system to meet specific resistance goal in any type of soil. D D B P P B Radial Delta D: Down-conductor B: Building foundation loop ground P: Grounding system Fig. B - Recommended Grounding Configurations 1. Installation of the Grounding System Each radial should consist of a trench (approx. 50cm deep x 20cm wide x 10m length). A ground rod should be driven at the end of each radial. The use of copper conductor is recommended, with a cross sectional area of not less than 50mm². Tin-plated copper is recommended for its corrosion resistance. All rods should be interconnected through the use of 1/0-19 strand bare conductor and ground rod clamps or TerraWeld® exothermic welding. The use of the TerraWeld® exothermic welding process is a safe and efficient way of providing a permanent connection between conductors. TerraWeld® connections will not rust or corrode over time. ESE Grounding Systems should utilize TerraDyne® Electrolytic Ground Electrodes and TerraFill® ground enhancement backfill to provide the desired low resistance ground system and stabilize low contact resistance at locations where the native soil has relatively high resistivity, low ground 8 moisture and/or where installations have limited footprints. A ground inspection/test well should be installed where the end of the down conductor terminates to the grounding system. This gives an access point for disconnection and future testing. Each down conductor should be provided with a means of disconnect for testing. These disconnect/test terminals may be located 2m above ground level and should be marked “Lightning Conductor” and the symbol: When the building or the protected structure has a foundation earth termination system for the electrical system, the ESE system earth termination systems should be connected to it with a standardized conductor. The ESE system earth termination components should be at least 2 m distant away from any buried metal pipe or electrical conduit, in case these conduits are not electrical connected to the main equipotential bonding of the structure. Down Conductor Routing Guidelines Bare or tin-plated copper conductor is recommended for use as the down conductor, although building steel and alternate materials are also allowed. NF C 17-102 requirements should be strictly adhered to as regards materials and design requirements for number and placement of TerraStreamer® ESE Terminals and down conductors. • The route of the down conductor should be as set out in the original design. Ensure no structural changes such as new antenna, mast installations, air conditioning towers or ducting has been installed. • DO NOT double the down conductor back against itself after changes of direction (i.e. 180° bend). • The down conductor may be installed internally or externally on the structure; however internal routing may reduce effectiveness and induce voltage surges into structures. • The down conductor should be installed as close (flush) as possible to the structure. • Minimize the number of bends and use the most direct route to the ground possible. • Ensure recommended bend radius is maintained, never less than 20cm. • If the down conductor has to cross other services make sure it crosses at right angles using a conduit that extends at least 1m past either side of the existing service. • The down conductor should be protected from damage at the lower end by installing a protective tube/conduit up to 2m from ground level. • Provide adequate separation between down conductors, preferably opposite building corners. 9 Number of Down Conductors and Grounds For a non-isolated ESE system, each terminal should be connected to at least two (2)down conductors. For a better current distribution, the two paths to ground should be situated on two different facades. If, due to physical constraints, it is not possible to route the down conductors on two different facades, an alternate installation method should be considered. When many ESE terminals are located on the same building, the down conductors shall be mutualized on a case by case basis, but a minimum of one down conductor is mandatory for each ESE terminal. When a natural component of a structure is utilized as a down conductor, at least one of them must be a dedicated down conductor complying with standard requirement. In case of an isolated ESE system, at least one down conductor is needed for each ESE terminal. Adaptor Down conductors should be attached to the TerraStreamer® ESE Terminal using the supplied adaptor as per Fig. D , and as recommended in sections following. Fig. D - Adaptor 10 2. Down Conductor Installation Guidelines Bare or tin-plated copper conductor is recommended for use as the down conductor. The route of the down conductor should be as set out in the original design. Ensure no structural changes have been implemented. The use of copper conductor is recommended, with a cross sectional area of not less than 50 mm². Tin-plated copper is recommended for its corrosion resistance. The copper should be of a grade normally used for commercial electrical work. Do not use insulated coaxial cable. The most direct path to ground is recommended, avoiding sharp bends. Minimize the number of bends and use the most direct route to the ground possible. Ensure recommended bend radius is maintained, never less than 20 cm. DO NOT double the down conductor back against itself after changes of direction (i.e. 180° bend). The down conductor should be installed as close (flush) as possible to the metal tower. If the down conductor has to cross other services make sure it crosses at right angles using a conduit that extends at least 1m past either side of the existing service. Suitable fasteners should be installed to secure all down conductors. Down conductors should be fastened on the basis of one point per meter. Avoid trip hazards Each down conductor should be connected to the grounding system. The Warning Labels supplied with TerraStreamer® ESE Terminals should be installed in locations where personnel may be in close contact to the down conductor(s). Down Conductor Mast Mast Base Do not exceed minimum bend radius. Fastener Roof Edge Fig. E - Down Conductor Routing Detail 11 3.

TerraStreamer® ESE Terminal Installation Stay clear of any overhead power lines or electrical sources. When installing the TerraStreamer® ESE Terminal, Alltec provides for two main configuration types. Guyed FRP Masts When installing the TerraStreamer® ESE Terminal with an Alltec FRP mast, refer to the supplied FRP Mast Installation Guide for assembly and installation instructions. Other important items to remember include: Using a crane or other suitable equipment is recommended for any installation over 6 meters in height, or for hazardous areas such as unsafe heights without appropriate safety railings. It is very important to keep the mast straight during the lift to avoid damaging the mast. The TerraStreamer® ESE Terminal must NOT be used as a slinging point. When lifting masts, ensure that the slings or ropes cannot damage the TerraStreamer® ESE Terminal. When lifting the mast, the down conductor must be tied off to the mast to remove any strain on the down conductor’s termination to the TerraStreamer® ESE Terminal and/or supplied adaptor. The TerraStreamer® ESE Terminal tip must be at least 2m above any aerial, equipment or structure on the roof. Please refer to NF C 17-102 standard or Alltec design for specific mast/ESE height requirements. Guy wires must be tight, but also consider roof load limitations (e.g. tighten guying grips to no more than 7 Nm of torque). 14 Installation Examples Using FRP Masts: TerraStreamer® ESE Terminal Guy Ring FRP Mast Guy Wire Mast Base Strike Counter Inspection Well Grounding System Fig. H - Mid Roof location TerraStreamer® ESE Terminal Guy Ring FRP Mast Guy Wire Mast Base Strike Counter Inspection Well Grounding System Fig. I - Edge Location 15 Metallic Masts Following installation of the TerraStreamer® ESE Terminal to a metallic mast, it will be necessary to connect the metallic mast to a down conductor in order to convey the lightning energy to the grounding system. The connection between the metallic mast and the appropriately sized down conductor should be completed by approved mechanical means or by exothermically welding (TerraWeld®) the down conductor at a practical point somewhere along the length of the mast. Particular care should be taken to ensure that compatible metals are used when connecting the down conductor to metallic masts (e.g. aluminum to copper connections require an approved bimetallic connector). It is important that a minimum of one third of the mast height be securely fixed to the structure to which the mast is mounted.

Lightning Strike Counter Installation The Lightning Strike Counter should be installed at a position along the down conductor length where it can be accessed easily for inspection. Typically the strike counter should be installed approximately 2m from ground level. The strike counter should be mounted away from areas where damage/loss may occur due to theft, vandalism or damage from nearby operations. The strike counter can be enclosed in a security enclosure but the display should be kept visible to allow for the checking of recorded strikes. 17 6. TerraStreamer® ESE Post Installation Verification The following should be checked for quality of workmanship and compliance to recommended installation instructions, approved design documents, and NF C 17-102/UNE 21 186 requirements: Correct TerraStreamer® ESE Terminal model and placement for proper zone of protection (verify model, height above structures, and radius of protection). Correct mast and any associated brackets and fasteners have been used for installation. Guying, anchor points and fastenings (if applicable). Down conductor size, routing, and attachment points Connection of down conductor to grounding system Grounding system (3-Point resistance test to verify 10 Ohms or less) Lightning Strike Counter installation is per recommended guidelines. Record “strike count” for later comparison. Safety and product labeling 7. Inspection/Maintenance Alltec recommends inspection and any required maintenance to be performed regularly and as listed below: Schedule • • • After each known lightning strike to the terminal. Once every twelve months minimum. If changes have been made to the protected structure. Checklist Check Lightning Strike Counter “strike count”, and compare to previous display number. Check Lightning Strike Counter installation for missing/damaged wires and connections. Check the strike counter for secure installation and record the number of strikes, if any. Check for any damage to the TerraStreamer® ESE down-conductor and grounding system. Check TerraStreamer® ESE Terminal body and tip for excessive pitting or other damage. Inspect the TerraStreamer® ESE Terminal and ensure that no dirt or other matter is embedded in the air gap between the center tip and the surrounding panel edges. Verify that the structure to be protected has not been modified or expanded since the last maintenance check. Make sure that the electrical continuity of all visible conductors is correct, 18 and that no conductors or other parts have been weakened by corrosion. Check that all rigging, mast mounts, and conductor fixings are secure and tight. Check that all down conductors and equipotential bonds remain correctly positioned and that they are securely attached and no damage or theft has occurred. All warning labels must still be in place and visible. Disclaimer Alltec TerraStreamer® Lightning Protection for Structures and Open Areas Using Early Streamer Emission (ESE) Technology “As in the case with anything related to the natural elements, lightning protection systems, designed and installed in accordance with this standard, cannot guarantee absolute protection to structures, persons or objects: however, applying this standard will significantly reduce the risk of protected structures being damaged by lightning.” NF C 17-102 (Forward) Neither the TerraStreamer® ESE Terminal nor any other lightning protection system to our knowledge can provide 100% protection from lightning. In order to provide the most effective Early Streamer Emission (ESE) Air Terminal technology available today, Alltec TerraStreamer® ESE Terminals are independently tested and certified to meet NF C 17-102 and UNE 21 186 standards. In addition, these modern standards have provided the applicable information contained in this Installation Guide to correctly implement a proper ESE system. The NF C 17-102 and UNE 21 186 standards are “applicable to lightning protection using early streamer emission lightning conductors of common structures of less than 60m high and of open areas.” It is recommended that any ESE installation strictly adhere to the general and detailed contents of the latest editions of the NF C 17-102 and UNE 21 186 standards. Alltec has developed the TerraStreamer® product according to internationally recognized standards. However, Alltec does not make any specific performance guarantees as no lightning protection system can be 100% effective. 19 WORLD HEADQUARTERS 64 Catalyst Drive, Canton, North Carolina 28716 USA TEL: +1.828.646.9290 | FAX: +1.828.412.4270 EMAIL: [email protected] © 2017 ALLTEC | 420-001 | 11/22/2017 www.alltecglobal.com ">
