Note: The fiber should not have armored jacketing which may be a source for Electro-
Magnetic 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
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.

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
