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 andpull the cable into the cabinet. 4. Connect fiber to the LC receptor located on the SIF electronic module. For location, referto 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 PowerPrime power for the RAN is 240 VAC, 20 Amps, single phase. A separate service disconnectand lightning arrestor for each RAN must be installed with proper grounding. An electric meteris optional depending on local agreements. A non-connectorized #14 AWG 3-wire power cable is provided with the RAN cabinet for theAC power connections. The power cable is connected to a wiring harness within the cabinet andis approximately 20 feet (6 meters) long. The stub end of the cable must be routed out of thecabinet through conduit to an external junction box (not provided). At the junction box, thepower cable must be connected to the AC power system wiring. The RAN electrical input fittingis located on the right rear of the cabinet, labeled “AC.”The AC power cable provides three wire leads for Line, Neutral, and Ground connections. AllAC wires must be run within conduit. The interface at the RAN is a 1 in. (2.54 cm) 90 degreereceptor elbow.For installation of AC power, the following materials are required (customer provided):• Electrical conduit• Conduit fittings• Connector sealant materialThe following tools are required to perform this procedure:• Wire cutters• Wire strippers• Conduit cutter• Conduit benderNote: The fiber should not have armored jacketing which may be a source for Electro-Magnetic Interference (EMI).Note: Power interfacing for the RAN must be performed by a licensed electrician.
ADCP-75-210 • Issue 1 • November 2006Page 50© 2006, ADC Telecommunications, Inc.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 theAC power junction box.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 ACcircuit 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 wiresand 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 Ampcircuit breaker.8. Place the circuit breaker in the ON position and then test the connectorized AC powercable 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. Thebatteries will need to be installed and under charge before they will be able to provide fullservice. Battery storage life is one year in an environmentally controlled area. Batteries shouldbe 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 manualfor specific information including charging recommendations, tests, and maintenance.2.7.6.1 Battery Safety RulesFor safety purposes, observe the following DO’s and DON’T’s when installing the batteries orperforming battery tests and maintenance: • DO use qualified personnel only for battery maintenance• DO follow all battery and charger manufacturer maintenance instructionsNote: All electrical work must comply with local codes and requirements. A locallylicensed electrical contractor is best qualified to perform this work. For operation at lessthan 20 Amps, consult with ADC Technical Service.Danger: Use extreme caution when working with high voltage AC power. Ensure all power isdisconnected before working on power circuits. Note: A reducer fitting must be provided to accommodate any size change to the conduit.

ADCP-75-210 • Issue 1 • November 2006Page 57© 2006, ADC Telecommunications, Inc.4 NON-STANDARD INSTALLATION PROCEDURESThis section contains other installation procedures that are not typically done at a RANinstallation. These procedures cover field installation of electronic modules and othercomponents like the RAN chassis fans.4.1 Installing an Electronic ModuleIf installing an electronic module in the field, refer to the appropriate procedure in this section.There is a procedure for each type of electronic module. For a comprehensive description of theelectronic modules including function, controls, and indicators, refer to the appropriate topic inSection 1.7 on Page 10.Typically, the RAN chassis is shipped populated with the appropriate modules based on the pre-ordered system configuration. Installation of electronic modules is only required wheninstalling a new electronic module or when changing the the system configuration.The electronic modules install into predetermined slots in the chassis identified by the labels onthe fan access panel above the chassis. For an illustration of the fan access panel labels and alisting of the slots, refer to Section 1.7 on Page 10.The interconnection diagram shown in Figure 39 and Figure 40 on the next two pagessummarizes the interconnections between the RAN chassis electronic modules and otherelectronic components of the RAN such as rectifiers and PAAs. Note: Not all options and features are supported in combination.Warning: Electronic components can be damaged by static electrical discharge. To preventESD damage, always wear an ESD wrist strap when handling electronic components.Note: The interconnection diagram shows a typical configuration. Other configurationsare possible that would be interconnected slightly differently.
