Estimated length of cable is 30 feet (9 meters) although this is dependent upon distance from the splice enclosure. Page 48 © 2007, ADC Telecommunications, Inc. ADCP-75-210 ♦ Issue 1 ♦ March 2007 ^ Note: The fiber should not have armored jacketing which may be a source for ElectroMagnetic Interference (EMI). 2. Install the compression nut and an appropriate sized split ring and bushing over the cable end. Note that the beveled side of the split ring should face toward the compression nut. 3. Insert the end of the cable into the fiber entry opening on the bottom of the cabinet and pull the cable into the cabinet. 4. Connect fiber to the LC receptor located on the SIF electronic module. For location, refer to Figure 11 on Page 16. 5. Pull back any excess fiber from within the NXD cabinet. 6. Tighten the compression nut on the fiber entry connector body to secure the cable. 7. Seal all connections. 2.7.5 Installing AC Power ^ Note: Power interfacing for the RAN must be performed by a licensed electrician. Prime power for the RAN is 240 VAC, 20 Amps, single phase. A separate service disconnect and lightning arrestor for each RAN must be installed with proper grounding. An electric meter is optional depending on local agreements. A non-connectorized #14 AWG 3-wire power cable is provided with the RAN cabinet for the AC power connections. The power cable is connected to a wiring harness within the cabinet and is approximately 20 feet (6 meters) long. The stub end of the cable must be routed out of the cabinet through conduit to an external junction box (not provided). At the junction box, the power cable must be connected to the AC power system wiring. The RAN electrical input fitting is located on the right rear of the cabinet, labeled “AC.” The AC power cable provides three wire leads for Line, Neutral, and Ground connections. All AC wires must be run within conduit. The interface at the RAN is a 1 in. (2.54 cm) 90 degree receptor elbow. For installation of AC power, the following materials are required (customer provided): • Electrical conduit • Conduit fittings • Connector sealant material The following tools are required to perform this procedure: • Wire cutters • Wire strippers • Conduit cutter • Conduit bender Page 49 © 2007, ADC Telecommunications, Inc. ADCP-75-210 ♦ Issue 1 ♦ March 2007 A ^ Note: All electrical work must comply with local codes and requirements. A locally licensed electrical contractor is best qualified to perform this work. For operation at less than 20 Amps, consult with ADC Technical Service. Danger: Use extreme caution when working with high voltage AC power. Ensure all power is disconnected before working on power circuits. Use the following procedure to install the AC power wiring: 1. Install outdoor conduit between the the AC power junction box and the AC power fitting (rigid 90 degree receptor elbow) on the back of the cabinet. 2. Use a UL approved outdoor conduit connector (not provided) to connect the conduit to the AC power junction box. ^ Note: A reducer fitting must be provided to accommodate any size change to the conduit. 3. Route the AC power cable through the conduit to the AC junction box. 4. Install the required AC power supply wires between the AC junction box and the AC circuit breaker box (by the junction box not within the RAN). 5. Strip off the insulation from the AC power cable wire leads and from the AC supply wires and connect the AC power cable wires to the AC supplier cable. 6. Connect the AC power to the AC wiring harness. 7. At the AC circuit breaker box, connect the AC power supply load wire(s) to a 20 Amp circuit breaker. 8. Place the circuit breaker in the ON position and then test the connectorized AC power cable within the cabinet for proper voltage levels and correct polarity. 9. Place the circuit breaker in the OFF position when testing is complete. 2.7.6 Installing Backup Batteries (Extended or Glitch) Backup batteries for the RAN may be either two-hours-extended or five minutes glitch. The batteries will need to be installed and under charge before they will be able to provide full service. Battery storage life is one year in an environmentally controlled area. Batteries should be checked prior to installation. Each battery should measure 12.6 V or greater across terminals. Any battery that measures less should not be used. Refer to the battery manufacturer’s manual for specific information including charging recommendations, tests, and maintenance. 2.7.6.1 Battery Safety Rules For safety purposes, observe the following DO’s and DON’T’s when installing the batteries or performing battery tests and maintenance: • DO use qualified personnel only for battery maintenance • DO follow all battery and charger manufacturer maintenance instructions Page 50 © 2007, ADC Telecommunications, Inc. ADCP-75-210 ♦ Issue 1 ♦ March 2007 • DO wear protective equipment (face shield, goggles, gloves) when working with o...
