2 Pole Mount Installation This chapter describes how to install the ECN on a utility pole.
Introduction You can install an ECN on any standard utility pole, in either the supply space or the common area. The ECN provides a carrying loop that you can tie with a rope so that you can easily carry the ECN while climbing the pole. The ECN is also small and light enough that you can carry it while working from a boom lift. After installation, the ECN can withstand a 1330 J/m (300 ft-lb) force, for example, from a utility worker standing on the unit.
Installation Location Typically, you install the ECN on a utility pole either in the supply space (near the service distribution transformer) or in the common area (3-½ to 4-½ meters or 12 to 15 feet above ground level). Important: Do not install the ECN in the communication space; that space is reserved for cable, telephone, and other companies to install their equipment. For optimal antenna performance, you should place the ECN as high on the utility pole as possible, in the supply space.
Attach Pole Mounting Bracket You connect the ECN to the utility pole using the hole that you drilled into the pole to prepare for installation; see Preparing for Installation on page 5. Place the bracket against the pole, insert the support bolt, and secure the bolt with a washer and nut, as shown in Figure 1. The Pole Mounting Bracket is designed to fit any standard utility pole. Figure 1.
Figure 2. Attach the ECN to the Pole Mounting Bracket Secure ECN to Pole Mounting Bracket To secure the ECN to the Pole Mounting Bracket, insert two screws to the bottom of the ECN to attach it to the Pole Mounting Bracket. These screws are already connected to the ECN, and are designed not to make contact with the pole. Figure 3 on page 8 shows a front view of the ECN attached to the Pole Mounting Bracket, with the bottom screws visible.
Figure 3. Secure the ECN to the Pole Mounting Bracket Connect the ECN to Power and the Network You make the connections to power and to the communications network at the bottom of the ECN. Figure 4 shows the bottom of the ECN, before installation. You can connect the ECN to either low voltage or medium voltage.
Complete the Installation After the installation is complete, perform the following tasks: 1. Inspect the connection of the ECN to the Pole Mounting Bracket. 2. Inspect the connection of the Pole Mounting Bracket to the utility pole. 3. Inspect the cabling connections to the ECN. The completed installation should look similar to the views depicted in Figure 2 on page 7. Note that the figure does not show the cabling connections to the ECN.
3 Pad Mount Installation This chapter describes how to install the ECN on a service distribution transformer that is mounted on a concrete pad.
Introduction You can install an ECN on the same concrete pad as a service distribution transformer, and secure it to the transformer without drilling holes into or otherwise damaging the transformer housing. After installation, the ECN is resistant to manual removal, and none of the electrical or communications network connections can be accessed by unauthorized personnel. The installation includes a bracket that you attach to the transformer housing and concrete pad.
Installation Location For optimal antenna performance, you should place the ECN as high on the distribution transformer as possible. However, most installations will require that the top of the ECN after installation extend no higher than the top of the transformer. A typical residential transformer measures between 46 cm (18 inches) and 74 cm (29 inches) in height.
4. Seal the top of the conduit inside the transformer cover with sealing putty or foam. This seal ensures that water and foreign objects cannot enter the transformer housing. 5. Seal the end of the conduit that is external to the transformer cover with sealing putty or foam. After the conduit and cabling are ready, you can install the ECN. See the next section, Performing the Installation. Performing the Installation To install the ECN using the pad mount method, perform the following tasks: 1.
Figure 5. Extend the Pad Mounting Bracket Attach Pad Mounting Bracket to Lifting Nut Because it is generally inadvisable to drill holes into the transformer housing, you use one of the 1.6 cm (5/8 inch) welded lifting nuts (inside the transformer cabinet and exposed through a hole in the transformer casing) as the installation point. Locate one of the transformer’s lifting nuts.
Figure 6. Attach the Mounting Bracket to the Transformer’s Lifting Nut Attach Conduit Housing to Pad Mounting Bracket To protect the electrical and network connections to the ECN, the Pad Mounting Bracket includes a Conduit Housing. The Conduit Housing is approximately 13 cm (5 inches) high and 30 cm (12 inches) wide. Attach the Conduit Housing to the bottom of the upper extension of the Pad Mounting Bracket, as shown in Figure 7 on page 17. You can perform this step prior to field installation.
Figure 7. Attach the Conduit Housing to the Pad Mounting Bracket Insert Conduit Thread into Conduit Housing To protect the electrical and network cabling as it enters the Pad Mounting Bracket Conduit Housing, insert a Conduit Thread unit into one of the available holes in the bottom of the Conduit Housing. The Conduit Thread should accommodate the locking nut for the conduit and the radius of one or more cable bundles.
Figure 8. Insert a Conduit Thread into the Conduit Housing Attach ECN to Pad Mounting Bracket After the Pad Mounting Bracket is securely attached to the transformer, and the Conduit Housing is securely in place, you can attach the ECN to the Pad Mounting Bracket. The top of the back side of the ECN includes two tabs that slide into the top of the Pad Mounting Bracket. Figure 9 on page 19 shows the ECN attached to the Pad Mounting Bracket.
Figure 9. Attach the ECN to the Pad Mounting Bracket Secure ECN to Pad Mounting Bracket To secure the ECN to the Pad Mounting Bracket, insert two screws to the bottom of the ECN to attach it to the Pad Mounting Bracket. These screws are already connected to the ECN, and are designed not to make contact with the transformer. Figure 10 on page 20 shows a front view of the ECN attached to the Pad Mounting Bracket, with the bottom screws visible.
Figure 10. Secure the ECN to the Pad Mounting Bracket Connect the ECN to Power and the Network You make the connections to power and to the communications network at the bottom of the ECN, which is inside the Conduit Housing. Figure 11 on page 21 shows the bottom of the ECN, before installation. You can connect the ECN to either low voltage or medium voltage.
Figure 11. Connect the ECN to Power and the Network Because the transformer’s lifting nut is not necessarily centered vertically with where you placed the 1.9 cm or 3.2 cm (¾” or 1-1/4”) flexible conduit relative to the transformer pad, ensure that the flexible conduit is long enough to reach both the Conduit Housing and the connections on the ECN.
Figure 12. Close and Lock the Conduit Housing Complete the Installation After the installation is complete, perform the following tasks: 1. Inspect the connection of the ECN to the Pad Mounting Bracket. 2. Inspect the connection of the Pad Mounting Bracket to the transformer. 3. Inspect the cabling connections to the ECN. 4. Inspect the transformer pad. The completed installation should look similar to the views depicted in Figure 13 and Figure 14 on page 23.
Figure 13. Complete ECN Installation, Viewed from the Left Figure 14.
Verifying Successful Installation Because the ECN has no external lights or displays, it uses an internal audio buzzer to provide indications of important installation-related states. The buzzer’s audio frequency is 2.4 kHz (as a 1/2 duty cycle square wave) and outputs 85 to 92 dBA of sound pressure, 3 which should be audible from at least 10 m (30 ft). Table 2 lists the sound patterns for the audio indicator. The audio indicator outputs its audio indicator patterns once only. Table 2.
4 Field Replacement for an ECN 7000 Series Device This chapter describes how to replace an ECN or an ECN’s battery pack after the ECN has been installed in the field.
Overview The ECN 7000 Series of products is designed to allow you to easily replace an ECN unit in the field after installation. For ECN units with the backup battery option, you can also easily replace the battery in the field. Although an ECN is designed for a 10 year operational life, because an ECN is typically installed in a location that exposes it to weather and other hazards, you might need to replace ECN units from time to time.
Replacing a Pad-Mounted ECN Important: Before replacing an ECN in the field, visually inspect the unit and its surroundings to ensure that the unit is not damaged and that it is safe to handle. You do not need to reinstall the Pad Mounting Bracket to replace an ECN unit. To remove a pad-mounted ECN: 1. If possible, use the ECoS system software to shut down the unit remotely, before beginning field replacement. 2. Unlock the Conduit Housing and open the Conduit Housing door. 3.
Figure 15. ECN Battery Compartment Location The ECN uses intelligent battery charging techniques to maximize the life of the battery. That is, the ECN occasionally discharges and recharges the battery to maintain battery capacity and prolong its life. A typical discharge/charge cycle can take up to 16 hours. During this time, the ECN could be vulnerable to power loss during the discharge cycle, so you should use dual battery packs.
