Install the Prism Remote Unit
INSTALL
THE
PRISM REMOTE UNIT
This section tells you how to install a Prism Remote Unit (PRU). If the PRU is already installed and you need to
add one or more RF Modules, go to "Install the RF Module(s)” on page 86.
PLANNING FOR A PRISM REMOTE UNIT INSTALLATION
Before you unpack the PRU, you should first plan for where it will be mounted and collect the tools and supplies
that are required to mount the PRU and then connect it to a Prism system.
Installation of the Prism Remote Unit may proceed separately from the installation of the corresponding Host
Unit.
Mounting Plans
The PRU has a low-profile design that requires minimal real estate for installation. The basic dimensions and
weights of the PRU are listed in Table 20 on page 35 and Table 19 on page 35.
The PRU should be mounted on a utility pole, mast, or on a flat surface. A Mounting Bracket ships with each
Remote. Installation consists of securing the bracket to the mounting surface (wood, concrete, or steel) and then
hanging the unit from the bracket. the PRU should only be mounted in a restricted access location.
Before mounting the PRU, make sure that the following requirements are met; observe all cautions and warnings
listed in "Mounting Cautions” on page 30.
•
The PRU must
–
be installed only in a restricted-access location
–
must be located as specified in the system design plan (not documented here). If a system design plan has
not been prepared, consult with the Technical Support for Wireless Products team for assistance (see
"DCCS Global Technical Support” on page 123).
–
must have ready access to the specified AC or DC power source.
•
If you mount the PRU in a horizontal position, you must mount it at a slight angle, with the top of the PRU
chassis angled higher than the bottom, which creates a slope that allows water or snow to run off the PRU
chassis. If it is mounted indoors, no slope required.
•
If you mount the PRU in an upside-down horizontal position (i.e., a ceiling mount), attach safety leashes that
can support the weight of a fully populated chassis (see Table 19 on page 35).
•
The site chosen must
–
conform to all local codes; required permits must be obtained prior to mounting a PRU
–
comply with the unit environmental specifications
–
be open to free air space on the bottom (cable entry end), the top, the front, and both sides
–
allow adequate clearance at the bottom of the PRU to provide access for attaching cables and for viewing
the LED indicator
–
provide 18 inches (45.7 cm) of clearance on the front and both sides of the PRU to allow doors to be
opened for service and to allow free air circulation
–
can bear the size and weight of the PRU enclosure, see Table 19 on page 35 and Table 20 on page 35

Steel Pole Installation Using Steel Banding
Always wear safety goggles when working with metal banding and when using tensioning tools.
This section describes how to secure a PRU to a steel pole using steel bands. In high earthquake risk areas,
CommScope advises in addition to banding, bolts should be used redundantly to ensure mechanical mounting
capable of surviving severe seismic activity. Typical areas where this attachment method are suggested are
Earthquake Risk Zone 4, per Bellcore GR-63-CORE, section 4.4.1.1. If you have application specific questions,
consult the Wireless Technical Assistance Center (TAC) for technical assistance (see "DCCS Global Technical
Support” on page 123). For information on bolting, see "Pole Mount Installation Using Bolts” on page 50.
Stainless-steel bands are used to secure the Mounting Bracket to a metal pole or mast that cannot be pierced with
a screw or bolt. The number of bands to be used is dependent on the configuration of the PRU as described in
Table 21 on page 40.
Refer to "Mounting Cautions” on page 30
before beginning this process.
Locate the Mounting Bracket provided with
the PRU Mounting Kit and obtain the tools
and supplies listed in "Tools Required for All
Mounting Methods” on page 40 and
"Additional Tools and Supplies Required for
Steel-Pole Mounting” on page 40.
CAUTION! The pole must have a
diameter of at least
6 inches.

Slide a buckle on the band and secure by doubling over under buckle, as shown in the illustration below, or
as instructed in manufacturer's instructions.
Bands should pass through each slot of the Mounting Bracket, from top to bottom, ensuring the band passes
over the top of the pins, as shown below, and again through the buckle.
Wrap the band around pole once more, passing through the slots in the Mounting Bracket and over pins, and
again through buckle. Double banding is critical to generate maximum radial compression of banding to pole
and Mounting Bracket.
Follow specific manufacturer's instructions for tensioning bands to recommended levels.
Roll tool over, bending band over itself at exit from the buckle, as shown above, or as instructed in the
manufacturer's instructions to temporarily secure tensioned band.
Cut band using tensioning tool as instructed in the manufacturer's instructions.

CONNECT A NETWORK CABLE TO THE PRU CHASSIS
The PRU provides a Network port that allows communications with the internal processor and access to the Host
LAN network. That is, this provides a LAN extension to the Host network. The Network port is 10/100/1000
BASE-T/TX (802.3ab compliant) MDI and requires a minimum of CAT 5 cable.
Although the interface might provide GigE, only 100 Mbps is provided for bandwidth between the Host and
Remote.
The network cable must be
terminated with a hardened
RJ-45 male connector for
connection to the Network
port, as shown in the graphic to
the right. The maximum cable
length is 300 feet (91.4 m).

CONNECT THE ANTENNA CABLE
Coaxial antenna cables must be routed from the antenna to the PRU. The cables must be terminated with an
N-Type male connector for connection to the PRU antenna port or the lightning surge suppressor (accessory,
required anytime the antenna is mounted in an area in which the antenna is susceptible to a lightning strike).
The antenna(s) used for this transmitter must be fixed-mounted on (outdoor/indoor) permanent structures.
RF exposure compliance is addressed at the time of licensing, as required by the responsible FCC Bureau(s),
including antenna co-location requirements of 47 CFR. 1.307(b)(3).
Use the following procedure to install the antenna cable(s). This procedure requires that you connect cable to one
Antenna connector at a time.
Refer to "Understanding RF Cable Rules” on page 26 to understand the relationship between antenna
numbers and Remote RF modules; this information makes sure you connect the Antenna connectors
correctly.
To avoid the risk of equipment damage, ensure that the AC/DC Power switch to the Remote Unit chassis and
the DC power switch to all RF Module bays are in their OFF position before connecting or disconnecting coaxial
cables; otherwise equipment damage may occur.
Remove the dust cap from an N-type female Antenna connector located on the underside of the unit, as shown
below. If you need to install cables to more than one Antenna connector, start in the rear and work forward,
applying the correct torque as you make each connection. Working from the rear port out provides you with
the space you need to apply the correct torque.

Connect a lightning surge suppressor to the antenna port; torque to 8 ±1 in-lbs to ensure full connection.
The lightning surge suppressor is included in the RF Module’s shipping container. Lightning surge suppressor(s)
are required anytime the antenna is mounted in an area in which the antenna is susceptible to a lightning
strike.
If the PRU has a Dual 20W SMR800 / PCS1900 RF Module (FWP-441T841MOD), you must install a FlexWave
Notch Filter (FWP-SPRINTFILTER) between the PRU and the antenna to provide protection from spurious
emissions in the Public Safety band below 861.35 MHz and the Cellular band above 869.5 MHz. For
information on how to install a Notch Filter, go to "FlexWave Notch Filter (FWP-SPRINTFILTER)” on page 114.
Ensure that the chassis ground wire is installed correctly (see "Ground the PRU Chassis” on page 56). For
maximum protection, the system ground wire must be attached to a low impedance ground system.
Route the coaxial antenna cable from the antenna to the underside of the PRU.
Cut the antenna cable to the required length and terminate with an N-type male connector.
Connect the antenna cable to the lightning surge suppressor or to the antenna port; apply 15 in-lbs (1.7 Nm)
of torque.
The antenna cable connections must be weather proofed (sealed) for outdoor installations.
Repeat the Step 2 through Step 8 for the remaining antenna cables.
DETERMINE THE CIRCUIT BREAKER OR FUSE FOR THE PRU
Use the information in this section to determine the circuit breaker or fuse that should be installed in the AC
circuit breaker box or the DC Power Source Distribution Panel:
•
An AC-powered PRU supports power input from a 90 to 240 Vac power supply.
•
A DC-powered PRU supports power input from a -40 to -60 Vdc power supply.
Power Consumption
Calculate the maximum power consumption, which determines the circuit breaker or fuse to use.
Review the PRU order to determine the number of DARTs, number of power supplies, and the number of
SFPs. Use this information to find the power consumption from Table 23 and Table 24 on page 77.
Enter the power consumption in the spaces provided below.
Add the Watts and enter the total in the Total Power Consumption field.

Install the Prism Remote Unit
Divide the total Watts by the input Voltage to determine the current (Amperes) requirements:
Total Watts / Input Voltage = Amps
Determine the circuit breaker or fuse size based on local codes and practices.
Circuit breaker or fuse size must be 20 Amps or less to protect the internal wiring of the PRU.
Power Consumption Tables
The PRU power supplies are > 80% efficient, both AC and DC versions. The data in Table 23 and Table 24 on
page 77 and the power-supply efficiencies can be used to estimate the input current for a given PRU
configuration. Use the following equation to calculate the input current draw:
Input Current = (Total Power Consumption / 0.80) / Input Voltage
For example, for a PRU with 1 SeRF Module, 1 SFP (36W Typical, 38W Max), and a single 20W 850/1900 HDM RF
Module (250W Typical, 330 W Max), then the Total Power Consumption would be 286W (Typical) and 368W
(Max). Therefore, for a 110VAC input, the current estimate would be 3.25 amps (Typical) and 4.18 amps (Max).

CONNECT THE POWER WIRING
The PRU supports both AC and DC power. Follow the steps appropriate to your system configuration:
•
"Option 1: Connect the AC Power Wiring” on page 78
•
"Option 2: Connect the DC Power Wiring” on page 81.
Option 1: Connect the AC Power Wiring
A 15-foot, 3-wire cable with connectors is provided for the AC power connections. The connector end of the cable
connects to the AC power port located on the bottom of the unit. The stub end of the cable must be routed to an
external junction box (not provided) for permanent connection to the AC power system wiring. If the cable must
be terminated with a plug to connect to the AC adapter, the plug must be provided by the installer.
The AC power source must supply between 100 and 240 Vac, 50 or 60 Hz, single-phase power through a circuit
breaker or fuse. The AC power cable provides three wire leads for line, neutral, and ground connections. The
power cable is rated for indoor or outdoor use and must not be placed within electrical conduit as this will
impede the cooling of the cable during usage. The electrical junction box and any conduit, wire, and fittings
required must be provided by the installer.
Use extreme caution when working with high voltage AC power. Ensure all power is disconnected before
working on power circuits.
All electrical work must comply with local codes and requirements. A locally licensed electrical contractor is
best qualified to perform this work. For additional information, consult with the CommScope DCCS Technical
Support (see "DCCS Global Technical Support” on page 123).
Use the following procedure to install the AC power wiring:
Use the information in "Determine the Circuit Breaker or Fuse for the PRU”
on page 75 to ensure that the correct circuit breaker or fuse required for
this installation is installed in the circuit breaker panel.
Locate the AC power cable that is provided separately with the PRU.
Route the power cable between the AC power port, located on the
underside of the PRU and the nearest AC power junction box as shown in
the graphic to the right. It may be necessary to install a new junction box if
an existing junction box is not available.
Secure the cable between the AC power port and the AC power junction box
per local practice. Leave sufficient slack in the cable to allow it to be easily
connected and disconnected from the AC power port.

Remove the dust cap from the AC power port located on the bottom of the PRU as shown below.
While trying to connect the AC power cable to the PRU AC power port, it is possible for the line terminal on
the cable connector to contact the ground pin on the power port. If the AC cable is energized, this will result
in a direct short to ground for the AC power. To avoid possible personal injury and equipment damage, always
turn the AC power off before connecting the AC power cable to the AC power port.
12
Connect the power cable connector to the AC power port; use the alignment key to ensure that the cable
correctly aligns with the connector. If the cable is not aligned correctly with the connector, connector pins
may be damaged.

Option 2: Connect the DC Power Wiring
All electrical work must comply with local codes and requirements. A locally licensed electrical contractor is
best qualified to perform this work. For additional information, consult with the CommScope Technical
Support for Wireless Products team (see "DCCS Global Technical Support” on page 123).
Use the information in "Determine the Circuit Breaker or Fuse for the PRU” on page 75 to ensure that the
correct circuit breaker or fuse required for this installation is installed in the DC Power Source Distribution
Panel.
Obtain a DC power cable that meets the following requirements:
•
The DC power cable can be 8 AWG or 6 AWG, 3- or 4-conductor power cable rated for outdoor use.
•
The wire colors must be green, red, and black.
•
The cable diameter must be .71 to .98 inches.
•
If a 4-conductor power cable is used, the extra conductor can be snipped off before installation.
•
If using 6 AWG wire, the installer must provide and use #10 stud size, 6 AWG ring terminals.
Remove the cable-gland plug from the bottom of the PRU chassis:

In a typical -48 Vdc plant, the highest potential is the 0 (ground or return) lead; you therefore:
– connect the 0 (ground or return) lead to the positive (+) connector (red wire)
– connect the -48 Vdc lead to the negative (-) connector (black wire)
– connect the third wire, if provided, to the Earth Ground terminal.
•
In a +48 Vdc plant, the highest potential is the +48 lead; you therefore:
– connect the +48 lead to the positive (+) connector (red wire)
– connect the 0 potential (ground or return) to the negative (-) connector (black wire)
– connect the third wire, if provided, to the Earth Ground terminal.
Use a Phillips screwdriver to torque the ring terminals to 18 in-lbs.
Use a 42 MM wrench to torque the large nut outside the cable gland to 44 in-lbs.
