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

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

ADCP-75-210 • Issue 1 • November 2006
• DO wear protective equipment (face shield, goggles, gloves) when working with or
around battery systems.
• DO use proper lifting techniques when working with batteries.
• DO use insulated tools when working on batteries.
• DO remove all rings and metal watchbands before working on batteries.
• DON’T service batteries individually. Replace pack as a unit.
• DON’T replace a defective pack with an alternate type. Use only the replacement packs
provided by ADC.
• DON’T lift batteries by their terminals.
• DON’T place tools, unconnected cables, or metal objects to rest on top of the batteries.
• DON’T use any chemical cleaners (ammonia, bleach, etc.) to clean batteries.
• DON’T remove vent caps or add anything to sealed, maintenance-free batteries.
• DON’T smoke, cause sparks, or carry an open flame near any battery system.
• DON’T approach any energized battery system that shows signs of over-charging or over
discharging (severe swelling, cover deformation, vent caps popping off). Disconnect and
isolate the battery system from all charging and discharging circuitry before approaching
the system.
• DON’T circumvent any device installed by the battery or charger manufacturer for the
purpose of protecting the battery system. These devices include fuses, circuit breakers,
disconnects, switches, etc.
2.7.6.2 Battery Installation
Use the following procedure to install the batteries:
Warn ing: Do not short battery connections together or to ground. The battery pack has high
current capacity and can cause burns or serious personal injury when shorted.
Warn ing: To avoid personal injury or fire damage, do not incinerate or mutilate the battery. Do
not short the battery terminals and do not store or operate the battery in an airtight container.
Warn ing: The batteries contain hazardous materials. Deliver defective batteries to an
authorized disposal center for disposal or recycling.
Caution: Before connecting batteries, be sure to turn off the low voltage connect switch located
on the rectifier. The LED will be OFF.
1. Open the RAN door.
2. Turn off the battery disconnect switch (labeled DISC) on the low voltage disconnect unit
in the RAN chassis. For location, refer to Figure 19 on Page 24. The LVD LED will light
up (red) when the batteries are disconnected.
3. Move the gravity latch in the battery drawer to the up position. Refer to Figure 34.

4. Pull out the battery drawer.
5. Move the gravity latch to the down position. Lock the telescopic slide into the locked out
position.
6. Install the batteries in the drawer as follows, referring to Figure 35 for extended batteries
and Figure 36 for extended batteries:
a. Place the batteries in the drawer in the configuration shown.
b. Wire the batteries in series as shown.
c. Find the wiring harness coiled up on the floor of the battery back up drawer and plug
the Anderson connectors together as shown.
7. Move the gravity latch up, push the battery drawer in, and move the gravity latch down.
8. Reconnect the battery disconnect switch (DISC) on the LVD unit. For location, refer to
Figure 19 on Page 24. The LVD LED on the low voltage disconnect unit should will turn
off when the batteries are reconnected.
